Linear Speed Formula In Circular Motion

When a body is in a circular motion, it has two different kinds of speeds.

1. Angular speed 
2. Linear speed 

Linear speed and angular speed together constitute the speed of a body in a circular motion. Linear speed in a circular motion pushes the body to move forward whereas angular speed is caused due to the centripetal force which constrains the body to continue its motion in a circular path. The centripetal force generates an inward pull and hence manages to restrict the motion to a circular path. The linear speed is responsible for propelling the body. Without the presence of the linear speed, the circular motion will cease. Without the presence of the angular speed, the circular motion would be disrupted and the motion will continue in a tangential direction. Hence, both the components are equally important for restricting the body to a circular path.
