Question

1. what will cause an object to change its direction

balanced forces
unbalanced forces

Explanation:

According to Newton's first law of motion, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Balanced forces result in no change in the object's motion (it will either remain at rest or continue moving at a constant velocity in a straight line). Unbalanced forces cause a change in the object's velocity, which can include a change in direction.

Answer:

Unbalanced forces
