Question

The definition Rectilinear Motion , circular motion, periodic motion

Answer 1

any object that can be in a straight line is called linear motion .any object that can be moved in circular path is circular motion .

Answer 2

Answer:

circular motion

It is not to be confused with radial velocity or rotational speed. In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
