The object will accelerate in the same direction as the unbalanced force. This statement best describes an unbalanced force acting on a moving object.
Option A
Explanation:
Force is only responsible for the motion of any object. Forces can be of two types, balanced force and unbalanced force. Balanced force will not contribute to the motion of any object. It will be useful to keep the object at rest. But unbalanced force is responsible for motion of any object.
An unbalanced force can make an object at rest to move from its static position and it can also accelerate the already moving object. If an unbalanced force acts on an already moving object, then this force may change in velocity i.e., speed along with direction of motion.
But the acceleration will be in the same direction as the unbalanced force. So the best statement which describes the unbalanced force acting on a moving object is that the object will accelerate in the same direction as the unbalanced force.
