Mechanics

This chapter sheds light on physics and its role in our day-to-day life. It discusses the major contributions and discoveries by some physicists. We also learn about the types of forces in nature and the link between physics and technology.

This chapter introduces us to units and measurements that are used in international systems. It explains the measurements of length, mass and time. It also briefly discusses the accuracy, precision, errors and dimensions of some physical quantities.

This chapter describes the motion of an object in a straight line. It explains the terms such as position, path length and displacement of an object. We also learn about speed, velocity and acceleration, kinematic equations and relative velocity.

This chapter discusses the concept of scalars and vectors along with vector addition, subtraction, multiplication and resolution. It will also throw light on motion in a plane, relative velocity in 2D and projectile motion.

This chapter sheds light on the laws of motion and their applications in real-life. It also covers the concept of conservation of momentum, the equilibrium of a particle in a circular motion and solving problems related to mechanics.

This chapter discusses the concepts of work, energy and power along with the different forms of energy. It also describes the work-energy theorem, the potential energy of a spring, conservation of mechanical energy and collisions.

This chapter discusses the system of particles and rotational motion. Here, we will learn about the centre of mass, linear and angular momentum, torque, the moment of inertia, etc. It also explains the kinematics and dynamics of rotational motion.

This chapter explores the concepts of gravitation and Kepler's laws regarding the motion of planets. It briefly discusses the acceleration due to the gravity of the earth and its surfaces.
