When an object moves in a circle with uniform speed, its speed remains constant, but the velocity changes when the object moves in a different direction. According to the first law of motion, a force is needed to change the state of the body. As with circular motion, the direction of the body's velocity changes, Also zero acceleration is not possible.Because centripetal acceleration will be there which is toward the centre.
