Which of the following best describes balanced forces?
Forces that cause an object to accelerate
Forces that are equal in magnitude and opposite in direction
Forces that act in the same direction
Forces that have no effect on an object's moton
What happens to an object when balanced forces act on it?
It accelerates
It changes direction
It remains at rest
It vibrates
Unbalanced forces result in:
No change in motion
Constant velocity
A net force and acceleration
Equal and opposite force
