Uniform Circular
Motion When an object follows a circular path at a constant speed, the motion of the object is called uniform circular motion. The word uniform refers to the speed which is uniform (constant) throughout the motion. Although the speed does not vary, the particle is accelerating because the velocity changes its direction at every point on the circular track.
The figure shows a particle P which moves along a circular track of radius `r` with a uniform speed `u`.
A particle is revolving at 1200 rpm in a circle of radius 30 cm. Then, its acceleration is

(c) `2370 ms^(-2)`
(d) `5055 ms^(-2)`
