Question

define C.M. & U.C.M.​

Answer 1

Explanation:

UCM ( Uniform Circular Motion)

Velocity change in a closed path can take place due to two reasons:

1. Change in rate of distance covered.

2. Change in direction of motion due to the curvature of path.

CM ( circular motion)

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

➟ 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.

➟ Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion.
