If the acceleration is zero, there is no change in velocity over time. Therefore, the final velocity (v) would be equal to the initial velocity (u), and the object would continue to move at a constant velocity.

If the acceleration of an object is zero, its velocity remains constant. According to Newton’s first law of motion, an object at rest stays at rest, and an object in motion continues at a constant velocity unless acted upon by a net external force. When acceleration is zero, there is no net force acting on the object, so it maintains its current state of motion. If the object is at rest, it remains at rest; if it is in motion, it continues moving at a constant speed in a straight line. In summary, zero acceleration implies a lack of change in velocity.
