Chapter 1: Physical World
Humans have always been curious about the world around them. The night sky with its bright celestial objects has fascinated humans since time immemorial.
The regular repetitions of the day and night, the annual cycle of seasons, the eclipses, the tides, the volcanoes, and the rainbow have always been a source of wonder. The world has an astonishing variety of materials and a bewildering diversity of life and behavior.
- What is Physics?
- Scope and excitement of physics
- Physics, technology and society
- Fundamental forces in nature
- Nature of physical laws
Chapter 2: Units and Measurements
Measurement of any physical quantity involves comparison with a certain basic, arbitrarily chosen, internationally accepted reference standard called unit. The result of a measurement of a physical quantity is expressed by a number (or numerical measure) accompanied by a unit.
Although the number of physical quantities appears to be very large, we need only a limited number of units for expressing all the physical quantities, since they are inter-related with one another. The units for the fundamental or base quantities are called fundamental or base units.
The units of all other physical quantities can be expressed as combinations of the base units. Such units obtained for the derived quantities are called derived units. A complete set of these units, both the base and derived units, is known as the system of units.

- Significant figures
- Dimensions of physical quantities
- Dimensional formulae and equations
- Applications of Dimensional analysis
Chapter 3: Motion in Straight Line
Motion is common to everything in the universe. It is the change in position of an object with time. In this chapter, you will learn how to describe motion.
For this, we develop the concepts of velocity and acceleration. We shall confine ourselves to the study of motion of objects along a straight line, also known as rectilinear motion.
- Position, path length and displacement
- Average velocity and average speed
- Instantaneous velocity and speed
- Kinematic equations for uniformly accelerated motion
- Relative velocity
Chapter 4: Motion in a Plane
As a simple case of motion in a plane, we shall discuss motion with constant acceleration and treat in detail the projectile motion. Circular motion is a familiar class of motion that has a special significance in daily-life situations. In this chapter, uniform circular motion will be discussed in some detail.
- Scalars and vectors
- Multiplication of vectors by real numbers
- Addition and subtraction of vectors – graphical method
- Resolution of vectors
- Vector addition – analytical method
- Motion in a plane
- Motion in a plane with constant acceleration
- Relative velocity in two dimensions
- Projectile motion
- Uniform circular motion
Chapter 5: Laws of Motion
A force is required to put a stationary body in motion or stop a moving body, and some external agency is needed to provide this force. The external agency may or may not be in contact with the body. This chapter will make you understand Aristotle’s fallacy, The law of inertia, Newton’s Laws of Motion, Conservation of momentum and some common forces in mechanics.
- Aristotle’s fallacy
- The law of inertia
- Newton’s first law of motion
- Second law of motion

- Conservation of momentum
- Equilibrium of a particle
- Common forces in mechanics
- Circular motion
- Solving problems in mechanics
Chapter 6: Work, Energy and Power
The terms ‘work’, ‘energy’ and ‘power’ are frequently used in everyday life. A farmer ploughing the field, a construction worker carrying bricks, a student studying for a competitive examination, an artist painting a beautiful landscape, all are said to be working.
In physics, however, the word ‘Work’ covers a definite and precise meaning. Energy is our capacity to do work. The word ‘power’ is used in everyday life with different shades of meaning. In this chapter, you will learn that there is at best a loose correlation between the physical definitions and the physiological pictures these terms generate in our minds.
- Notions of work and kinetic energy : The work-energy theorem
- Kinetic Energy
- Work done by a variable force
- The work-energy theorem for a variable force
- Concept of potential energy
- The conservation of mechanical energy
- Potential energy of a spring
- Various forms of energy : the law of conservation of energy
Chapter 7: System of Particles and Rotational Motion
Any real body which we encounter in daily life has a finite size. In dealing with the motion of extended bodies (bodies of finite size) often the idealized model of a particle is inadequate.
In this chapter we shall try to go beyond this inadequacy. We shall attempt to build an understanding of the motion of extended bodies. A large class of problems with extended bodies can be solved by considering them to be rigid bodies. In a number of situations involving bodies such as wheels, tops, steel beams, molecules and planets on the other hand, we can ignore that they warp (twist out of shape), bend or vibrate and treat them as rigid.
- Centre of mass
- Motion of centre of mass
- Linear momentum of a system of particles
- Vector product of two vectors
- Angular velocity and its relation with linear velocity
- Torque and angular momentum
- Equilibrium of a rigid body
- Moment of inertia
- Theorems of perpendicular and parallel axes
- Kinetics of rotational motion about a fixed axis
- Dynamics of rotational motion about a fixed axis
- Angular momentum in case of rotations about a fixed axis
- Rolling motion
Chapter 8: Gravitation
Early in our lives, we become aware of the tendency of all material objects to be attracted towards the earth. Anything thrown up falls down towards the earth, going uphill is lot more tiring than going downhill, raindrops from the clouds above fall towards the earth and there are many other such phenomena.
Historically it was the Italian Physicist Galileo who recognised the fact that all bodies, irrespective of their masses, are accelerated towards the earth with a constant acceleration. It is said that he made a public demonstration of this fact. To find the truth, he certainly did experiments with bodies rolling down inclined planes and arrived at a value of the acceleration due to gravity which is close to the more accurate value obtained later.
- Kepler’s laws
- Universal law of Gravitation
- The gravitational constant
- Acceleration due to gravity of the earth
- Acceleration due to gravity below and above the surface of earth
- Gravitational potential energy
- Escape speed
- Earth satellite
- Energy of an orbiting satellite
- Geostationary and polar satellites
Chapter 9: Mechanical Properties of Solids
A solid has definite shape and size. In order to change (or deform) the shape or size of a body, a force is required. If you stretch a helical spring by gently pulling its ends, the length of the spring increases slightly. When you leave the ends of the spring, it regains its original size and shape.
The property of a body, by virtue of which it tends to regain its original size and shape when the applied force is removed, is known as elasticity and the deformation caused is known as elastic deformation. In this chapter, you will learn about the following:
- Elastic behavior of solids
- Stress and Strain
- Hooke’s Law
- Stress-strain curve
- Elastic moduli
- Applications of elastic behavior of materials
Chapter 10: Mechanical Properties of Fluids
In this chapter, we shall study some common physical properties of liquids and gases. Liquids and gases can flow and are therefore, called fluids. It is this property that distinguishes liquids and gases from solids in a basic way.
Fluids are everywhere around us. Earth has an envelope of air and two-thirds of its surface is covered with water. Water is not only necessary for our existence; every mammalian body constitute mostly of water. All the processes occurring in living beings including plants are mediated by fluids. Thus understanding the behavior and properties of fluids is important.
- Streamline flow
- Bernoulli’s principle
- Surface tension
Chapter 11: Thermal Properties of Matter
We all have common sense notions of heat and temperature. Temperature is a measure of ‘hotness’ of a body. A kettle with boiling water is hotter than a box containing ice. In physics, we need to define the notion of heat, temperature, etc. more carefully.
In this chapter, you will learn what heat is and how it is measured, and study the various processes by which heat flows from one body to another. Along the way, you will find out why blacksmiths heat the iron ring before fitting on the rim of a wooden wheel of a horse cart and why the wind at the beach often reverses direction after the Sun goes down.
You will also learn what happens when water boils or freezes, and its temperature does not change during these processes even though a great deal of heat is flowing into or out of it.
- Temperature and heat
- Measurement of temperature
- Ideal-gas equation and absolute temperature
- Thermal expansion
- Specific heat capacity
- Change of state
- Heat transfer
- Newton’s law of cooling
Chapter 12: Thermodynamics
Thermodynamics is the branch of physics that deals with the concepts of heat and temperature and the inter-conversion of heat and other forms of energy. It is a macroscopic science which deals with bulk systems and does not go into the molecular constitution of matter. Thermodynamic description involves relatively few macroscopic variables of the system, which are suggested by common sense and can be usually measured directly.
- Thermal equilibrium
- Zeroth law of Thermodynamics
- Heat, Internal Energy and Work
- First law of thermodynamics
- Specific heat capacity
- Thermodynamic state variables and equation of state
- Thermodynamic processes
- Heat engines
- Refrigerators and heat pumps
- Second law of thermodynamics
- Reversible and irreversible processes
- Carnot engine
Chapter 13: Kinetic Theory
Kinetic theory explains the behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules. This is possible as the inter-atomic forces, which are short range forces that are important for solids and liquids, can be neglected for gases.
The kinetic theory was developed in the nineteenth century by Maxwell, Boltzmann and others. It gives a molecular interpretation of pressure and temperature of a gas, and is consistent with gas laws and Avogadro’s hypothesis. It correctly explains specific heat capacities of many gases.
- Molecular nature of matter
- Behaviour of gases
- Kinetic theory of an ideal gas
- Law of equipartition of energy
- Specific heat capacity
- Mean free path
Chapter 14: Oscillations
The study of oscillatory motion is basic to physics; its concepts are required for the understanding of many physical phenomena. In musical instruments, like the sitar, the guitar or the violin, we come across vibrating strings that produce pleasing sounds.
The membranes in drums and diaphragms in telephone and speaker systems vibrate to and fro about their mean positions. The vibrations of air molecules make the propagation of sound possible.
- Periodic and oscillatory motions
- Simple harmonic motion
- Simple harmonic motion and uniform circular motion
- Velocity and acceleration in simple harmonic motion
- Force law for simple harmonic motion
- Energy in simple harmonic motion
- Some systems executing simple harmonic motion
- Damped simple harmonic motion
- Forced oscillations and resonance
Chapter 15: Waves
Waves transport energy and the pattern of disturbance has information that propagate from one point to another. All our communications essentially depend on transmission of signals through waves. Speech means production of sound waves in air and hearing amounts to their detection. Often, communication involves different kinds of waves.
For example, sound waves may be first converted into an electric current signal which in turn may generate an electromagnetic wave that may be transmitted by an optical cable or via a satellite. Detection of the original signal will usually involve these steps in reverse order.
- Transverse and longitudinal waves
- Displacement relation in a progressive wave
- The speed of a travelling wave
- The principle of superposition of waves
- Reflection of waves
- Doppler effect
