Understanding of Basic Properties of Circular Motion

Circular Motion is an angular motion in which distance of a particle in motion remain constant from a

fixed point, the center of the circular trajectory of the motion.

Basic Properties of Circular Motion of a particle are –

Angular Displacement,

Angular Velocity and

Angular Acceleration which are related in same manner as linear motion displacement, velocity and

acceleration are related.

Angular Velocity is the time derivative of angular displacement and Angular Acceleration is the time

derivative of angular acceleration. Similar to linear motion angular acceleration can also be given as

product of angular velocity and the derivative of angular velocity with respect to angular displacement.

For Uniform Angular Acceleration we can also use the Angular Speed Equations for angular motion in

similar manner to linear speed equations.
