Question

how we can convert uniform circular motion into rectilinear motion​

Answer 1

Explanation:

Uniform circular motion refers to a body moving in a circular path without angular acceleration (circular motion is impossible without centripetal acceleration). Angular acceleration is the rate of change of angular velocity, and angular velocity is the rate of change of angular displacement. In short, any angular quantity is the same as its linear quantity, except it describes the angle between the axis of rotation and the position of object, rather than the distance-based quantities.

Analogy between linear and angular motion

As described before, rotational motion can be understood by analogy to linear motion. This section will list the analogs and then explain why the analogy works.

For accelerated linear motion, we had 3 quantities: velocity, acceleration and displacement.
