In this chapter, the Circular or Angular motion of a body is described. The motions are in the form of Angular Displacement, Angular Velocity, Angular Acceleration. What is the relation b\/w Angular and Linear Velocities is also described. The force needed to move a body in a circular path is the Centripetal Force. Moment of\u00a0 Inertia, Angular Momentum, Artificial Satellite, Real and Apparent Weight, and Orbital Velocity also works on the principle of Circular motion. It also includes Artificial Gravity, Geostationary Orbits, and Communication Satellite. Newton and Einstein gave different views about Gravitation. So, this is the information about this chapter.
