Kinematics describes the motion of points, bodies, and systems of bodies but the masses of those points, bodies and system of bodies and the forces that help to the motion are not considered in it. In this chapter, we will learn to practice on motion in one dimension without calculus and with calculus and graph i.e., uniform velocity, uniform and non-uniform acceleration, distance and average speed, preview of differential and integral calculus and graphs of various parameters of motion. We will also practice on motion in two dimension and relative motion in which we will practice on components of vectors, basics of projectile motion, various parameters of projectile, equation of trajectory, problems involving one and two-dimensional motion and motion in moving medium.

Newton’s Laws of Motion are the laws which describe the relationship between a body and the forces which are acting upon that body, and the motion of body in response to those forces. In this chapter we will learn to practice on drawing forces, friction and circular motion i.e., various forces, free body diagram, static and kinematic friction, calculation of radial and tangential force and circular motion problems with and without friction. We will also practice on application of newton’s laws i.e., simple applications of 2nd law, trick to find relation between accelerations and advanced problems of newton’s laws.

The change in the kinetic energy of an object or body is the work done on that object/body and the rate of doing this work is called power. In this chapter, we will learn to practice on calculation of work i.e., work and its sign and work done by constant and variable force. We will also practice on work, energy theorem and power i.e., conservative force and conservation of mechanical energy.

Center of mass is the mass-weighted center of the object. The event in which two bodies tend to occupy same position at the same time is called collision. In this chapter we will practice on center of mass and principle of momentum conservation i.e., locating center of mass, velocity, and acceleration of center of mass, conservation of linear momentum, conservation of momentum and mechanical energy. We will also practice on impulse and collision.

When a body rotates, all the particles of the body perform circular motion. The axis of rotation is the line on which the centers of circles lie and it is perpendicular to the plane of circles. In this chapter we will learn to practice on moment of inertia, statics i.e., moment of inertia of point mass, moment of inertia for continuous bodies, parallel and perpendicular axis theorem, torque about point and equilibrium. We will also practice on fixed axis dynamics and combined motion i.e., kinetic and work energy theorem, angular acceleration, angular momentum of point, body and conservation laws, constraint and rolling toppling, rolling dynamics, angular momentum and conservation and kinetic energy in combined motion.
