(b) Moon, the natural satellite of earth, moves in uniform circular motion round
the earth.
(c) Cyclist moving on a circular track with a constant speed exhibits uniform
circular motion

Uniform circular motion Uniform linear motion

1. When a body moves in circular path with 1.An object is said to move in uniform linear
uniform speed , it's motion is called uniform motion , if it travels in straight line and covers
circular motion. equal distance in equal time interval.

2. Motion is said to be accelerated. 2 .Motion is unaccelerated.

3. SPEED is constant but direction of motion 3.. SPEED is constant and constant velocity.
