The International Physics Olympiad (IPhO) is one of the world’s best-known competitions for secondary-school physics students. Families searching for IPhO 2027 dates, 2026 results, eligibility, syllabus, experimental physics, past papers and national selection need to start with the correct organiser. The official international IPhO uses national teams, while School Connect’s independent SCO Physics Olympiad offers class-wise learning and an examination for Grades 8–12. This guide explains both routes separately and includes official global resources, a preparation plan, real-world physics projects and 20 original worked questions.
IPhO latest news: 2026 results and 2027 host
Checked 26 October 2026. The 56th International Physics Olympiad took place in Bucaramanga, Colombia, in July 2026. See the official IPhO 2026 host website for the concluding news and announcements. At IPhO 2026, all five members of India’s official physics team earned gold medals, as confirmed by the Government of India’s 12 July 2026 announcement. Since official IPhO prizes are awarded to individuals, readers should use the organiser’s final medal records rather than treat one news headline as an official country league table.
Next edition: IPhO 2027 is the 57th edition. Saudi Arabia was awarded hosting rights by the IPhO International Board during the July 2026 event in Colombia, according to the Saudi Press Agency’s dated hosting announcement. It is expected in July 2027; specific event days, city and delegation instructions should be checked with the organising committee when final bulletins are issued. An older future-host schedule should not be used instead of a later confirmed board decision.
2027 city and dates: two national organisers differ. Germany’s official Physics Olympiad programme currently lists 4–12 July 2027 in Riyadh, Saudi Arabia for the international competition. However, Kuwait’s national qualifying organisation still says the host city is to be announced and gives only July 2027. The German dates and city are a valuable national-programme planning listing, not a separately verified final Saudi host bulletin; delegations should await the Saudi organising committee’s authoritative invitation and logistics. The Saudi government announcement confirms the country, not the city or exact days.
What students should watch for next
- Official IPhO 2027: German national organiser lists 4–12 July in Riyadh; Kuwait’s national portal still calls the host city unannounced. Wait for the host’s own final bulletin before treating the listing as definitive.
- National selection deadlines: Kuwait’s 5–25 October 2026 application window has ended; Germany’s second round is listed for 10 November 2026; India’s NSEP is scheduled for 22 November 2026.
- National selection: country-specific enrolment, qualifying results, laboratory training and final team announcements.
- Official IPhO 2026 papers: the Colombia host now has an official questions page with separate theoretical and experimental exam/answer-sheet sections. Check actual file downloads there; individual PDF availability and complete worked solutions were not independently verified in this check. The IPhO Secretariat archive remains the official historical resource.
- SCO Physics 2026–27: new class-wise practice resources and dates in the SCO live cycle calendar.
Official International Physics Olympiad versus School Connect SCO IPhO
Official IPhO: national teams and laboratory experiments
The official International Physics Olympiad Secretariat states that the competition began in Warsaw, Poland, in 1967. It is a high-level physics competition for selected secondary-school students. The official statutes normally permit up to five contestants and two team leaders per country. Contestants must meet the secondary-school conditions and must not be older than 20 years on 30 June of the competition year.
The official competition has two separate examination days. One is a five-hour theory examination with three theoretical problems. The other is a five-hour experimental examination with one or two laboratory problems. The tests are not a general online multiple-choice examination. Students ordinarily reach this event through selection by their country’s responsible physics Olympiad body.
SCO Physics Olympiad: independent class-wise learning and examination
School Connect’s SCO International Physics Olympiad (SCO IPhO) is a separate, independently organised physics competition for Grades 8–12, with multiple-choice exam preparation. Students can learn physics using free chapter-wise learning materials, linked educational videos and practice questions on the School Connect platform. SCO participation is not an entry or selection route to the official IPhO national teams.
The shared short name “IPhO” should not cause confusion. Follow the international Secretariat for official IPhO history, rules, papers and national-team events; follow SCO’s own exam page for School Connect’s grade eligibility, syllabus and booking. In particular, SCO MCQ practice is different from the official IPhO five-hour theory and five-hour practical challenges.
Official IPhO eligibility, exam format and marking
- Who participates? Normally secondary-school students selected by their country’s national body; national citizenship, residency and stage eligibility are separately determined by that body.
- Age rule: no older than 20 on 30 June of the competition year, under current IPhO statutes.
- Team size: up to five student contestants and two accompanying team leaders in a normal delegation.
- Theory: five hours for three problems requiring creative modelling, clear reasoning and mathematical explanation.
- Experimental: five hours for one or two tasks involving apparatus, measurements, data analysis and uncertainty.
- Marking: written and practical solutions are evaluated under event procedures. Official medals, honourable mentions and award rules follow the IPhO statutes—not SCO’s independent awards system.
International Physics Olympiad syllabus: what should students study?
The authoritative source is the official IPhO syllabus and statutes. Unlike a single school’s physics textbook, IPhO problems combine several concepts, reward careful physical reasoning and may provide unfamiliar information in the question itself. Study the areas below in a connected way, including how to justify assumptions and check limiting cases.
1. Mechanics, motion and mathematical modelling
- Position, velocity, acceleration, vectors, relative motion and Newton’s laws.
- Energy, work, potential energy, conservation of momentum and collisions.
- Circular motion, gravitation, torque, rotation and equilibrium.
- Oscillations, coupled systems and the role of simplifying approximations.
2. Electromagnetism and circuits
- Electric charge, fields, potential, capacitance and conductors.
- Direct-current circuits, electrical measurements, resistance and Kirchhoff’s laws.
- Magnetism, forces on charges and currents, electromagnetic induction.
- Interpreting circuit and field data with suitable sign conventions and units.
3. Thermodynamics and properties of matter
- Temperature, thermal equilibrium, heat transfer and expansion.
- Ideal gases, energy, pressure, the first law and thermodynamic processes.
- Fluids, pressure, buoyancy and properties of matter.
- Estimations, dimensional analysis and checks that results obey physical constraints.
4. Waves, optics and relevant modern physics
- Simple harmonic motion and travelling waves, sound and interference.
- Reflection, refraction, diffraction and optical instruments.
- Waves and photons, atomic physics and the modern physics ideas described in the syllabus.
- Connecting several areas rather than memorising isolated equations.
5. Experimental physics and uncertainty
- Use instruments safely, identify variables and make repeatable measurements.
- Estimate resolution, random uncertainty and possible systematic bias.
- Construct meaningful graphs, determine slope and intercept and interpret physical units.
- Communicate measurements and conclusions while explaining limitations.
IPhO past papers and solutions: official, free sources
A reliable international practice route is the International Physics Olympiad Secretariat documentation and past-problems archive, which contains historical theoretical and experimental papers and solutions. Students should choose a year they can reasonably approach, attempt the problem before viewing the official solution, and study the problem-solving method rather than copying a final formula.
For the latest edition, the IPhO 2026 official questions page now labels experimental and theoretical examination and answer-sheet sections, although complete downloadable PDFs and worked solutions could not be independently confirmed from the accessible page; its organising committee site is the first place to check for newly published event materials, followed by the Secretariat archive when its listing is updated. For earlier examples, the official history and papers section includes links to 2022 (Switzerland), 2023 (Japan) and 2024 (Iran), as well as decades of older material. Download files directly from the authorised archive rather than uncertain third-party answer banks.
How to learn effectively from a real IPhO paper
- Read the problem without opening the solution, and identify the unknown quantity and physical assumptions.
- Draw a diagram, list known values with SI units, and decide which conservation laws or physical principles may apply.
- Try a simplified model or limiting case before starting long algebra.
- Write an explanation for each equation and compare the result with an estimate.
- Read the official solution to identify a better method, then revisit the problem a few days later.
How to qualify for the international IPhO: national selection worldwide
There is no single public international student-registration form for the official IPhO. The national team is chosen through each country or territory’s authorised programme. The following official country examples show why selection routes differ.
India: NSEP → INPhO → selection camp → international team
India’s Homi Bhabha Centre for Science Education (HBCSE) 2026–27 Physics Olympiad programme leads toward the 2027 IPhO through a five-stage pathway, beginning with the National Standard Examination in Physics (NSEP) run by IAPT and followed by Indian National Physics Olympiad (INPhO), training and selection stages. For 2026–27, NSEP is scheduled for 22 November 2026, 08:30–10:30 IST, and INPhO for 31 January 2027, 09:00–12:00 IST. The Stage I student-enrolment deadline was 14 September 2026. Check the official brochure and updated announcements rather than using another organiser’s form.
United States: F=ma → USAPhO → physics team
The American Association of Physics Teachers (AAPT) U.S. Physics Team programme uses the F=ma mechanics examination and U.S. Physics Olympiad (USAPhO), followed by selection and training. The older AAPT 2026 registration notice says that 2027 F=ma registration was expected to open in mid-October 2026, but the live 2027 opening date, closing date and registration form were not independently confirmed on 26 October 2026. Do not use a 2026 registration form or assume the 2027 application is open. Students should use the current AAPT rules for eligibility, exam access and approved proctoring rather than assuming every international school can register.
Australia: national science exams → summer school → team
The Australian Science Innovations (ASI) programme begins with national Australian Science Olympiad exams, then a summer school and final international team selection. Physics is one of the participating science subjects. Details of the next national exam and eligible year levels belong on the official ASI page.
Kuwait and other countries: the national organising body decides
The Sabah Al-Ahmad Center for Giftedness and Creativity’s Kuwait selection information specifies 5–25 October 2026 for eligible Kuwaiti Grades 9–11 applicants. That published registration deadline has passed as of 26 October 2026; its national online qualifying examination is expected in November, with the day still to be announced. Do not mistake an old “register now” button for an extended deadline. Germany’s official national Physics Olympiad calendar lists a second selection round on 10 November 2026; its first-round enrolment closed in September. Other countries may use their physics society, education ministry, Olympiad trust or a specialist national selection committee. Start with the officially authorised organisation and check the relevant eligibility, application and exam schedule. A national selection programme does not become a universal international registration portal.
SCO Physics Olympiad: Grade 8 to Grade 12 subject guide
Students wanting age-specific School Connect physics learning can begin with the official SCO Physics Olympiad hub, then select the current class syllabus. SCO provides free chapter-wise resources, linked learning videos and practice questions and distinct registration for its own programme.

Twenty original Physics Olympiad practice questions with explanations
These are new, original multiple-choice teaching exercises arranged for School Connect-style Grades 8–12. They help build foundations, but they are not official IPhO past problems. The international national-team contest is much more advanced and includes lengthy written and laboratory tasks. Use the class-specific questions first, then move toward authentic official past IPhO problems as your skills develop.
Grade 8 — original practice
Question 1. A force of 24 N is spread over an area of 6 m². What is the pressure?
A. 4 Pa B. 6 Pa C. 30 Pa D. 144 Pa
Answer: A. 4 Pa. Pressure = force ÷ area = 24 N ÷ 6 m² = 4 pascals.
Question 2. Why cannot sound travel from the Moon to Earth through empty space?
A. Sound always travels only downwards B. Sound needs a material medium C. Sound moves faster than light D. Sound has no frequency
Answer: B. Sound needs a material medium. Sound requires matter (such as air, water or solids) to transfer mechanical vibrations.
Question 3. A light ray strikes a plane mirror at 35° to the normal. What is the reflection angle?
A. 55° B. 70° C. 35° D. 25°
Answer: C. 35°. The law of reflection says the angle of reflection equals the angle of incidence, measured from the normal.
Question 4. Why do rough shoe soles help on a dry walking surface?
A. They remove gravity B. They create an electric field C. They eliminate all movement D. They generally improve grip through friction
Answer: D. They generally improve grip through friction. Appropriate friction helps shoes resist slipping, though wet or icy surfaces may behave differently.
Grade 9 — original practice
Question 5. A runner moves 150 m in 30 s at constant speed. What is the speed?
A. 5 m/s B. 4 m/s C. 30 m/s D. 180 m/s
Answer: A. 5 m/s. Average speed = distance ÷ time = 150 ÷ 30 = 5 metres per second.
Question 6. What is the net force on a 2 kg object accelerating at 3 m/s²?
A. 1.5 N B. 6 N C. 5 N D. 9 N
Answer: B. 6 N. Newton’s second law: F = ma = 2 × 3 = 6 N.
Question 7. What is the kinetic energy of a 2 kg object moving at 4 m/s?
A. 8 J B. 12 J C. 16 J D. 32 J
Answer: C. 16 J. Kinetic energy = 1/2 mv² = 1/2 × 2 × 4² = 16 joules.
Question 8. In ideal free fall near Earth’s surface, with air resistance ignored, what happens to acceleration?
A. It depends on mass only B. It is always zero C. It continuously doubles D. It is approximately constant downward
Answer: D. It is approximately constant downward. Gravity gives approximately constant acceleration g near Earth’s surface when air drag is ignored.
Grade 10 — original practice
Question 9. A resistor has 12 V across it and carries 3 A. What is its resistance?
A. 4 Ω B. 9 Ω C. 15 Ω D. 36 Ω
Answer: A. 4 Ω. Ohm’s law gives R = V/I = 12/3 = 4 ohms.
Question 10. Two identical 6 Ω resistors are connected in parallel. What is their total resistance?
A. 12 Ω B. 3 Ω C. 6 Ω D. 36 Ω
Answer: B. 3 Ω. Two equal resistances in parallel have half the resistance of one: 6/2 = 3 Ω.
Question 11. Which statement about the image formed by a plane mirror is correct?
A. It is always magnified B. It is always formed on a screen C. It is virtual and upright D. It is inverted vertically
Answer: C. It is virtual and upright. A plane mirror creates an upright virtual image that appears behind the mirror.
Question 12. An ideal 60 W bulb runs for 2 hours. How much electrical energy does it use?
A. 0.03 kWh B. 0.06 kWh C. 1.2 kWh D. 0.12 kWh
Answer: D. 0.12 kWh. Energy = power × time = 0.060 kW × 2 h = 0.12 kWh.
Grade 11 — original practice
Question 13. A projectile leaves level ground at 20 m/s, 30° above horizontal. Ignoring air drag with g = 10 m/s², how long until it lands at the same height?
A. 2 s B. 1 s C. 4 s D. 10 s
Answer: A. 2 s. Flight time T = 2u sinθ/g = 2 × 20 × 0.5/10 = 2 s.
Question 14. A 2 kg object changes speed from 0 to 4 m/s along one straight line. What is the magnitude of its impulse?
A. 2 N·s B. 8 N·s C. 4 N·s D. 16 N·s
Answer: B. 8 N·s. Impulse = change in momentum = mΔv = 2 × 4 = 8 N·s.
Question 15. At 2 m depth in water, what is the approximate additional hydrostatic pressure? Use ρ = 1000 kg/m³ and g = 10 m/s².
A. 2 kPa B. 10 kPa C. 20 kPa D. 200 kPa
Answer: C. 20 kPa. Δp = ρgh = 1000 × 10 × 2 = 20,000 Pa = 20 kPa.
Question 16. For an ideal gas undergoing an isothermal process, what is the change in internal energy?
A. Always positive B. Always negative C. Equal to work done D. Zero
Answer: D. Zero. The internal energy of an ideal gas depends only on temperature, which is constant in an isothermal process.
Grade 12 — original practice
Question 17. A capacitor stores 20 μC at a potential difference of 5 V. What is its capacitance?
A. 4 μF B. 100 μF C. 25 μF D. 0.25 μF
Answer: A. 4 μF. Capacitance C = Q/V = 20 μC/5 V = 4 μF.
Question 18. What does Kirchhoff’s loop rule say for a closed circuit loop?
A. The current must be zero B. The algebraic sum of potential differences is zero C. Each resistor has the same voltage D. Magnetic field is always zero
Answer: B. The algebraic sum of potential differences is zero. The sum of rises and drops in electrical potential around a closed loop is zero.
Question 19. An ideal transformer has 1000 turns on its primary and 200 on its secondary. If the primary gets 240 V AC, what is secondary voltage?
A. 240 V B. 120 V C. 48 V D. 12 V
Answer: C. 48 V. Vs/Vp = Ns/Np = 200/1000 = 0.2, so Vs = 0.2 × 240 = 48 V.
Question 20. Measured pairs (x,y) are (2,5) and (6,13). What is the slope of the straight line through them?
A. 4 B. 3 C. 8 D. 2
Answer: D. 2. Slope = Δy/Δx = (13−5)/(6−2) = 8/4 = 2.
Two fully worked advanced physics problems
Worked problem: momentum in a perfectly inelastic collision
A 0.50 kg cart moves at 2.0 m/s on a level low-friction track toward a stationary 0.50 kg cart. The carts stick together. Assuming negligible external horizontal impulse, conservation of momentum gives (0.50 × 2.0) + (0.50 × 0) = (0.50 + 0.50) v, so v = 1.0 m/s. The initial kinetic energy is 1.0 J, while the final kinetic energy is 0.50 J. Momentum is conserved, but kinetic energy decreases because the collision is inelastic. This is a mathematical thought experiment, not a direction to stage collisions.
Worked experiment: estimate gravitational acceleration from a pendulum
Using teacher-approved equipment, imagine a simple pendulum of length 1.00 m makes ten small-amplitude oscillations in 20.1 s. The estimated period is T = 20.1/10 = 2.01 s. For a small-angle pendulum, T = 2π√(L/g), so g ≈ 4π²L/T² ≈ 9.77 m/s². Discuss why human stopwatch reaction time, uncertainty in length and releasing at too large an angle can affect this result. Repeat timings and record their spread. Do not swing heavy objects near other people.
A six-week international physics preparation roadmap
- Week 1 — Mechanics foundation: practise vectors, forces, energy, momentum, dimensions and physical estimates.
- Week 2 — Electricity and magnetism: reason through circuit laws, electric fields, capacitance and magnetic-force examples.
- Week 3 — Thermal physics and oscillations: study ideal gases, heat transfer, fluid pressure and simple harmonic motion.
- Week 4 — Optics and waves: solve ray diagrams, wave and interference problems, and check units.
- Week 5 — Experiment and data: use safe school apparatus, repeat readings, fit graphs, estimate uncertainty and write conclusions.
- Week 6 — Past-paper methods: attempt appropriate official IPhO problems untimed, review the authorised solutions, then revisit mistakes. Confirm national-selection requirements separately.
Use this IPhO preparation worksheet today
Choose one mechanics, electricity or experiment problem. Before checking the answer, copy the following simple worksheet into your notebook. It helps you practise the process used in real Olympiad problem-solving, even when your current questions are still grade-level exercises.
- Question: Write the physical quantity you need to find, including its SI unit.
- Known information: List given values such as mass, time, distance, resistance or temperature.
- Diagram: Sketch the forces, circuit, ray path or experimental apparatus.
- Assumptions: State whether you are ignoring friction, air resistance or heat losses and why.
- Principle: Choose a law such as Newton’s second law, conservation of energy or Ohm’s law.
- Calculation: Substitute units, show intermediate steps and avoid premature rounding.
- Reasonableness: Check dimensions, signs, limiting cases and whether the size of the answer makes sense.
- Reflection: Compare with a worked explanation, record one improvement and solve a related problem later.
Worked notebook example: A trolley of mass 0.80 kg accelerates at 2.5 m/s² when external forces have a net horizontal effect. Its net force is F = ma = 0.80 × 2.5 = 2.0 N. Draw an arrow in the acceleration direction, state that the net force points the same way, and verify that kg × m/s² has units of newtons. For an actual school experiment, record measured values and their uncertainty rather than inventing numbers.
How to study experimental physics safely
- Use supervised apparatus: school-approved low-voltage sources, scales, rulers and safe mechanical setups; do not use mains electricity, lasers, hazardous chemicals or unstable loads without professional supervision.
- Measure more than once: repeat timings and record every result, even when one differs from the expected value.
- Use uncertainty: note instrument precision and the likely causes of variation.
- Graph the variables: decide what should go on each axis and what the slope physically represents.
- Check limits: ensure calculated quantities have meaningful signs, magnitudes and dimensions.

Frequently asked questions about IPhO 2027 and physics Olympiads
What is the International Physics Olympiad (IPhO)?
The official IPhO is an annual international competition for nationally selected secondary-school students, including theoretical and experimental physics examinations. Its international Secretariat publishes the statutes and syllabus.
Where and when will IPhO 2027 be held?
Saudi Arabia was awarded hosting rights for the 57th IPhO in July 2027. Germany’s official national selection programme lists Riyadh, 4–12 July 2027, while Kuwait’s national programme still calls the city unannounced. Treat the German dates as an organiser planning listing until the Saudi host’s final bulletin confirms city, days and delegation instructions.
Where was IPhO 2026 held?
The 56th official International Physics Olympiad was held in Bucaramanga, Colombia in July 2026.
Who won IPhO 2026?
The official IPhO awards individual students, not a single championship trophy for one country. India’s entire five-student delegation earned gold medals; see the official host and national delegations for results.
How old can official IPhO participants be?
The official statutes state that contestants must not exceed age 20 on June 30 of the competition year and must meet the secondary-school and national-team requirements.
Can I register individually for the official IPhO?
Normally no. Students qualify through their country’s official national-selection programme; each participating country normally sends up to five competitors and two team leaders.
How many exams are in the official IPhO?
The official format has a five-hour theory exam with three problems and a five-hour experimental exam with one or two tasks, held on separate days.
What subjects are in the official IPhO syllabus?
Topics include mechanics, electromagnetism, thermodynamics, oscillations and waves, optics, and relevant modern physics and experimental methods. Read the current official syllabus for depth and details.
Where can I find authentic IPhO past papers and solutions?
Use the IPhO Secretariat’s documentation and past-problems archive. The host of each recent edition may release newer examinations before the central archive adds them.
Is School Connect SCO IPhO affiliated with official IPhO?
No. SCO IPhO is an independent School Connect Olympiad programme with separate enrolment, grades and multiple-choice exam format, not the official national-team route.
Which classes are eligible for SCO Physics Olympiad?
The School Connect Physics Olympiad subject page describes Grades 8–12. Students should verify the available class and active cycle during registration.
When is the next SCO IPhO exam?
The current public Winter 2027-labelled calendar shows upcoming November and December 2026 slots, including 6, 14 and 15 November and 4, 12 and 20 December. Check the actual registration form for class-specific availability.
What is NSEP and INPhO in India?
India’s national pathway includes NSEP (the Stage I National Standard Examination in Physics) and INPhO (Stage II), followed by selection and training stages. It is run through IAPT and HBCSE, not School Connect.
What are India’s 2026–27 Physics Olympiad selection dates?
HBCSE publishes NSEP for 22 November 2026, 08:30–10:30 IST, and INPhO for 31 January 2027, 09:00–12:00 IST. The 2026 student-enrolment window has ended; verify the official notices for changes.
How can a USA student qualify for IPhO?
The American Association of Physics Teachers runs the F=ma qualifying examination and USAPhO pathway, followed by team training and selection. Check the 2027 official registration and eligibility rules.
Does every country have the same national selection system?
No. Selection bodies, citizenship rules, exam dates and training programmes differ. Contact the responsible national physics olympiad organisation in your country.
Are the 20 solved questions below actual official IPhO problems?
No. They are original grade-level multiple-choice learning questions. Official IPhO problems are advanced theory and experiments rather than a class-wise MCQ test.
How should I prepare for IPhO experimental physics?
Practise measurement, graph fitting, estimating uncertainty, describing the apparatus and checking physical units. Use school-approved equipment and qualified supervision.
Does a good IPhO score guarantee admission or a scholarship?
No. Universities and scholarship organisations apply their own policies; awards and eligibility should never be treated as automatic admission guarantees.
How do I stay up to date on IPhO news?
Follow the official IPhO Secretariat, the current official host, and your country’s team-selection body. This guide maintains a dated update section linking to those primary sources.
