Question

drifference between

uniform and non uniform circular motion​

Answer 1

Answer:

For a body in uniform motion, the net external force is always equal to zero. An example of uniform motion is a body sliding on a frictionless surface with a constant velocity. NON-UNIFORM MOTION - DEFINITION A body is said to have non-uniform motion if its velocity changes with time.

Answer 2

Answer:

U.C.M and Non-U.C.M

1. Circular motion with constant angular speed is known as uniform circular motion. Circular motion with variable angular speed is called as non-uniform circular motion

2. For U.C.M, α = 0 For non-U.C.M, α≠ 0

3. In U.C.M, work done by tangential force is zero In non-U.C.M, work done by tangential force is not zero.

4. Example: Motion of the earth around the sun Example: Motion of a body on vertical circle.
