Answer 2

Answer:

(a) An object with a constant acceleration but with zero velocity. Change in velocity is known as acceleration.  Hence, we can say that an object moves with acceleration and constant speed in a uniform circular motion.

(b) An object moving with acceleration but uniform speed. Considering the uniform circular motion of a body, the direction of motion of the body is always along the tangent. Here, speed is constant.

(c) An object moving in a certain direction with acceleration in the perpendicular direction.
