Chapter 1 – Physical World
The physical world is referred to as the complexity in nature and solving its own complexities will give us new insights into this physical world. It is referred to as the analysis of nature conducted in order to understand how the world around us performs.
Chapter 2 – Units and Measurements
Units and measurement which is given in class 11 physics textbook offer basic knowledge about how the quantities are measured and the types of units that are used with them.
Chapter 3 – Motion In A Straight Line
If an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. Motion in a straight line is nothing but linear motion. As the name suggests, it’s in a particular straight line, thus it can be said that it uses only one dimension.
Chapter 4 – Motion In A Plane
Motion in a plane is the motion in 2 dimensions, for instance, projectile motion, circular motion and so on. The reference to analyze a 2 Dimensional motion, will be the origin with two coordinate axes i.e X and Y.
Chapter 5 – Laws Of Motion
The property of an object by virtue of which it cannot change its state of uniform motion along a straight line or rest on its own is called as inertia. It is the measure of the mass of a body. There are 3 types of inertia.
- Inertia of rest
- Inertia of motion
- Inertia of direction
Chapter 6 – Work, Energy, and Power
Work is the measurement of energy transfer that takes place when an object is displaced by an external force applied in the direction of the displacement.
The rate of doing work is called power.
The capacity for doing work is called Energy. It may exist in kinetic, potential, thermal, chemical, electrical, nuclear, or various other forms. The SI unit of energy is the same as that of work.
Chapter 7 – System of Particles and Rotational Motion
Rotation is what you achieve when you constrain a body and fix it along with a straight line. This means that the body can only turn around the line, which is defined as rotational motion. A ceiling fan, a potter’s wheel, a vehicle’s wheel are all examples of rotational motion.
Chapter 8 – Gravitation
When we talk about gravitation or gravity it is a naturally occurring phenomenon or a force which exists among all material objects in the universe.
Chapter 9 – Mechanical Properties of Solids
All materials have an elastic limit beyond which, if continuous stress is applied, they will start losing their ability to exhibit perfect elastic behaviour and start deforming. In contrast, plasticity is the non-reversible deformation of solid materials on the application of forces.
Chapter 10 – Mechanical Properties of Fluids
Fluids are the substances which move or flow in a certain direction when an external force is applied to them. Fluids can be either gases or liquids. However, when we study fluids and their mechanical properties, we come across two topics namely hydrodynamics and hydrostatics.
Chapter 11 – Thermal Properties of Matter
By definition, matter or material is anything that has mass and occupies space. Everything we see around us is matter. For example, a water bottle is made up of plastic or any metal, both of which are examples of matter.
The matter has properties or characteristics, by which they can be identified. The major properties of materials can be categorized under:
- Mechanical properties of materials
- Chemical properties of materials
- Physical properties of materials
- Dimensional properties of materials
- Classification Of Material Property
Chapter 12 – Thermodynamics
Thermodynamics is concerned with the relationship between other forms of energy and heat. It explains how thermal energy is converted from other forms of energy. The energy coming from heat is termed Thermal energy. When the tiny particles within an object move, they generate heat, more heat is generated, when these particles move at a faster pace.
Chapter 13 – Kinetic Theory
The kinetic theory of gases explains the behavior of molecules, which should further explain the behavior of an ideal gas. Ideal Gas equation consists of the pressure (P), volume (V), and temperature (T) of gases at low temperature and the equation is: PV = nRT
Where n = number of moles in the gas R = gas constant having value 8.314JK−1mol−1
Chapter 14 – Oscillations
Oscillation is a measure of some repetitive variation, as a function of time. It can be measured with respect to a state of equilibrium. The most common and simplest example for oscillation is the motion of a simple pendulum.
Chapter 15 – Waves
We can witness four types of waves. They are:
- Mechanical Waves- which can exist in material media and follows Newton’s laws.
- Transverse waves are referred to those whose particles oscillate in a perpendicular motion of the direction of propagation of the wave
- Longitudinal waves are referred to those whose particles oscillate along the way of the propagation of the wave
- When the waves move from one point of the medium to another is called progressive wave
