Question

what happens to an object when it experiences an unbalanced force?
○ it remains at rest
○ it vibrates in place
○ it changes motion or direction
○ it stays in uniform motion

Explanation:

According to Newton's second law of motion, an unbalanced force acting on an object causes a net force, which results in a change in the object's motion (including speed or direction). An object remains at rest or in uniform motion only when forces are balanced (Newton's first law). Vibrating in place is not the general effect of an unbalanced force on an object's overall motion. So the correct option is the one stating it changes motion or direction.

Answer:

C. It changes motion or direction
