For an object moving in uniform circular motion, which of the following must be true? The object must be travelling at a constant velocity. The object must travel with a constant acceleration. The object must travel with a constant velocity and a constant speed. The object must be travelling at a constant speed.

An object moves in a circular path at a constant speed. Which of the following is true? A. The car’s acceleration is zero because it has a constant speed B. The car’s acceleration is not zero and causes the car to slow down C. The car’s acceleration is not zero and causes the car to speed up D. The car’s acceleration is not zero and causes the change in the direction of the car’s velocity E. None from the above

Assertion (A) The speed of a body in uniform circular motion is constant.Reason (R) In uniform circular motion, the acceleration of the body is constant.Both (A) and (R) are true and (R) is the correct explanation of (A).Both (A) and (R) are true but (R) is not the correct explanation of (A).(A) is true but (R) is false.(A) is false but (R) is true.
