Chapter 5: Work, Energy and Power

The interconnection of work, power and energy are examined in detail in this chapter. The idea of the work done by forces that are constant and variable is presented, and then kinetic and potential energy. The chapter focuses on the work-energy and the law of conservation of energy. Elastic and inelastic collisions are also studied as well as calculations of power in various situations.

Also check,

Chapter 6: System of Particles and Rotational Motion

This chapter is an extension of the analysis of motion to particle systems. It brings about the centre of mass and motion of the centre of mass. Rotational motion, torque and angular momentum are also taught to students. The chapter discusses the concept of moment of inertia and how to compute it in various bodies, rolling motion and conservation of angular momentum, which is very important in understanding the dynamics of rotation.

Also check,

Chapter 7: Gravitation

The gravitation is concerned with the law of gravity by Newton and the motion of bodies influenced by the force of gravity. Students are made aware of the concepts of acceleration due to gravity, its dependence on the height and depth, and other concepts like mass and weight. The laws of planetary motion have been presented by Kepler and they have been applied in a practical manner such as satellite motion, escape velocity and orbital velocity which makes the chapter very practical and interesting.

Chapter 8: Mechanical Properties of Solids

This chapter describes the behavior of solid materials to external forces. It presents concepts such as stress, strain, Hooke law, and modulus of elasticity. The various forms of the elastic moduli, including, Young, shear and bulk moduli are elucidated using examples. Another important thing that is discussed in the chapter is the Poisson ratio and the elastic potential energy in a stretched body, which is important to understand the strength of materials.

Also Check,

Chapter 9: Mechanical Properties of Fluids

Fluids do not behave like solids and this chapter concentrates on their behavior. Students learn about pressure in the fluids and Pascal law and buoyancy explained by the principle given by Archimedes. The concept of viscosity and fluid resistance is presented with examples such as movement through liquids. The chapter also describes the concept of surface tension and the theorems of Bernoulli that are used in aerodynamics, blood flow, and engineering.

Also Check,

Chapter 10: Thermal Properties of Matter

This chapter points out the behavior of substances in the presence of heating. It describes heat, temperature, calorimetry, specific heat capacity and change of state. The thermal expansion of solids, liquids, and gases is discussed with real life examples. The idea of thermal conductivity and the law of cooling developed by Newton are also introduced, which would set the students further along the line of thermodynamics.

Also Read,

Chapter 11: Thermodynamics

One of the most significant physics chapters is thermodynamics. It makes the definition of temperature through the zeroth law, internal energy and heat transfer through the first law, and entropy and direction of heat flow through the second law. The chapter also discusses the heat engines, refrigerators, and efficiency, which could be applied to both household and industrial processes.

Also Check,

Chapter 12: Kinetic Theory

This is a chapter that describes the molecular theory of gases. It covers the assumptions of the kinetic theory, derivation of the pressure by gases and the mean free path concept. The kinetic theory forms the basis of gas laws, and the root mean square (RMS) speed, degrees of freedom and equipartition of energy are presented, so that the microscopic behaviour of matter is easily understood.

Also Check,

Chapter 13: Oscillations

Simple harmonic motion (SHM) is a periodic motion, and that is what is the main topic of this chapter. Students get to know about equations of SHM, its graphical form and its energy conversion. The concept of resonance is also presented (along with Damped and forced oscillations in JEE and NEET) which can explain much of natural and artificial systems including musical instruments and bridges.

Also read,

Chapter 14: Waves

The last chapter is the introduction of the wave motion, including longitudinal and transverse. It describes the velocity of the waves in various media, superposition principle, and how standing waves are formed. Theories such as air column resonance, beats, and the Doppler effect are also discussed that provide a complete picture of the phenomena of waves in the natural and technological world.
