Question

1. what can you infer from the statement, velocity of an object is zero? a. object is in linear motion with constant velocity. b. object is moving at a constant speed. c. object is either at rest or it returns to the initial point. d. object is moving in a straight line without changing its direction.

Explanation:

Velocity is a vector quantity with both magnitude (speed) and direction. When velocity is zero, the object has no motion (at rest) or has come back to its starting - point where the net displacement is zero resulting in zero velocity. Options a, b, and d imply motion which is inconsistent with zero velocity.

Answer:

C. Object is either at rest or it returns to the initial point.
