Objects change their motion due to unbalanced forces.
In the context of physics, when forces acting on an object are balanced, they cancel each other out, and the object will either remain at rest or continue to move at a constant velocity. This is described by Newton's first law of motion, also known as the law of inertia.
On the other hand, when forces are unbalanced, the net force acting on the object results in a change in its state of motion. This can involve starting to move, stopping, changing direction, or changing speed.
In summary:
- Balanced Forces: No change in motion. The object remains at rest or continues to move at a constant speed in a straight line.
- Unbalanced Forces: A change in motion occurs; the object's velocity changes (speed or direction).
So, the correct answer to your question is unbalanced forces.
