What is the difference between uniform circular motion and non uniform circular motion? Give examples.

Sr. NoU.C.MNon-U.C.M
1.Circular motion with constant angular speed is known as uniform circular motionCircular motion with variable angular speed is called as non-uniform circular motion
2.For U.C.M, α = 0For non-U.C.M, α≠ 0
3.In U.C.M, work done by tangential force is zeroIn non-U.C.M, work done by tangential force is not zero.
4.Example: Motion of the earth around the sunExample: Motion of a body on vertical circle.

State four examples where centripetal force is experienced by the body.
