In physics, circular motion is a movement of an object along the circumference of a circle or rotationalong 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. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the movement of the center of mass of a body.
Examples of circular motion include: an artificial satellite orbiting the Earth at a constant height, a fan's blades rotating around a hub, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gearturning inside a mechanism.
Since the object's velocity vector is constantly changing direction, the moving object is undergoing acceleration by a centripetal force in the direction of the center of rotation. Without this acceleration, the object would move in a straight line, according to Newton's laws of motion.

Hello friend!!
Rajdeep here...
When a body moves in a circular path with constant speed but variable velocity, it is said to be in Uniform Circular Motion.
While executing circular motion, a Centripetal force acts on the body, directed towards the centre. An equal force, called the Centrifugal force (imaginary force) acts in the direction opposite to that of centripetal force, so that the body remain balanced.
An uniform circular motion is an accelerated motion with a variable velocity, as direction of motion continuously changes.
Also, a body will execute circular motion if it is pivoted at a point and is made to rotate by applying some external forces. In this case, the body rotates because it experiences a torque.
