Physics

The object moving in a circular path at a constant speed is in uniform circular motion.

An object is said to be in uniform circular motion when it moves in a circular path at a constant speed. Although the speed is constant, the direction of the velocity vector is constantly changing. The object is constantly accelerating towards the center of the circle due to centripetal acceleration.

Option A, Uniform linear motion

In uniform linear motion, an object moves in a straight line with a constant speed. The direction of the object's velocity remains the same throughout the motion.
