Answer: Uniform velocity, variable acceleration
Notes: Uniform circular motion occurs when a body moves in a circular path with constant velocity. The acceleration of a body experiencing uniform circular motion is always directed toward the center of the circle (centripetal acceleration) or ac = v r 2 . where v is the body’s velocity, and r is the radius of the circle. This acceleration is constant in magnitude but changes in direction, Therefore, it is variable at every point of the circular path that is tangential to the radius.
