Motion of System of Particles and Rigid Body

This topic describes the centre of mass of a system and its significance. It also contains the derived mathematical expression to prove centre of mass along with the example of rod and lamina.

This topic explains how to derive the three equations of rotational motion. It includes the use of angular displacement, angular velocity and angular acceleration for derivation. We will also study the application of equations for solving questions.

This topic explains the moment of inertia by considering rotation about a fixed axis. It also explains the radius of gyration with the help of equations and diagrams.

This topic covers the theorems of parallel and perpendicular axes along with their proofs. It derives the formula to calculate the moment of inertia of a body moving about a parallel axis or an axis perpendicular to its plane.

In this topic, we will acquaint ourselves with the physical quantities that are defined as vector products of two vectors. It also briefs on the concept of torque.

In this topic, we will discuss the concept of angular momentum with the aid of various examples. It highlights the law of conservation of momentum, along with its proof. We will also discuss examples of an ice skater and the ballet dancer here.

In this topic, we will learn how to express the work done in terms of torque and angular displacement. It highlights the formula of energy and power for rotational motion. We will also come across their definition for the same.

This topic is all about the comparison of rotational and linear motion. It highlights the difference in terms such as displacement, velocity, acceleration, force and many more. We will also study the difference in formulas of each term here.
