Uniform circular motioncan be described as themotionof an object in acircleat a constant speed. As an object moves in acircle, it is constantly changing its direction. At all instances, the object is moving tangent to thecircle.

Uniform circular motion defines the motion of an object traveling at a constant speed around a fixed center point or axis. The object travels around a curved path and maintains a constant radial distance from the center point at any given time. Realistically speaking, a perfect circle does not exist, but it is useful to study the case of a perfect circle in order to understand how an object might move around an ellipse and to approximate the motion of an object that is almost circular in nature. Some examples of this type of motion are the orbit of a planet, a car going around a circular track or a conical pendulum.

The motion of the particle along the circumference of the circle , with constant angular velocity is known as uniform circular motion.

The motion of a body in a circle with a constant speed is known as uniform circular motion
