What is the main difference between balanced and unbalanced forces?

• Balanced forces cause an object to move, while unbalanced forces cause an object to stay at rest.

• Balanced forces cause an object to accelerate, while unbalanced forces cause an object to remain at rest or move at a constant velocity.

• Balanced forces are always equal in magnitude and opposite in direction, while unbalanced forces are not.

• Balanced forces are always greater than unbalanced forces.
