Detailed Solution

The above statement is True.
Yes, “the rate at which the speed and direction of a moving object vary over time” is called acceleration. Even “if the speed is constant, motion in a circle accelerates because the direction is always shifting”. While velocity is the rate of change of displacement with time, acceleration is the rate of change of velocity with time. Because both terms are time-dependent, time is used twice in the context of acceleration.
