Question

Q.3 Define uniform circular motion. State two
characteristics of circular motion.​

Answer 1

Explanation:

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.

It is a periodic motion with definite period and frequency. Speed of particle remains constant but velocity changes continuously. It is an accelerated motion. Work done in one period of U.C.M is zero.

Answer 2

Answer:

When an object moves in a circular track/path with uniform speed, it's motion is called uniform circular motion.

Two Characteristics of circular motion are :-

1)  An object undergoing circular motion should experience an inward acceleration.

2) For an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration.
