Detailed Solution

The above statement is True.
Since acceleration is the change in velocity per unit of time, we can only conclude that there is no acceleration in the absence of a force. As a result, the velocity stays the same. According to Newton's first law of motion, a moving object with a constant velocity requires no net force to move it. Therefore, the object will continue to move if it is already doing so.
