Answer:
When an object moves in a circular track/path with uniform speed,it's motion is called uniform circular motion. example-if the athlete moves with a velocity of constant magnitude along the circular path,the only change in his velocity is due to the change in the direction of the motion.
Explanation:
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.
Example - an artificial satellite orbiting the Earth at a constant height,
Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction . At all instances, the object is moving tangent to the circle.
Example - Revolution of earth around the sun..
