Consider an object moving with a uniform velocity u in a straight line. Let it be given a uniform acceleration ‘a’ at time t = 0 when its initial velocity is u. As a result of the acceleration, its velocity increases to v (final velocity) in time t and s is the distance covered by the object in time t.
A motion along a circular path is called as a circular motion. When a body (or object) moves along a circular path, then its direction of motion (or direction of speed) keeps changing continuously. As the velocity changes (due to continuous change in direction) So, the motion along a circular path is said to be accelerated.
Where a body moves in a circular path with uniform speed (constant speed), its motion is called uniform circular motion.
A circular path can be considered to be made up of an indefinite number of tiny sides, and a body moving along such a circular path changes its direction of motion continuously.
