उत्तर
A force is necessary to change the speed as well as the direction of motion of an object.
Explanation:
- A net force on an object causes acceleration, which means the speed or direction of motion changes.
- If no net force acts, the object keeps its current velocity (it stays at rest or moves in a straight line at constant speed).
