Question

an object motion changes
when the forces acting on the object remain balanced

Answer 1

. This means that the object will continue to move at a constant velocity or remain at rest if it was initially stationary. The object will not accelerate or decelerate if the forces acting on it are balanced. To change the motion of the object, an unbalanced force is required to either speed it up, slow it down, or change its direction. Balanced forces result in no change in the object's motion.
