True or false? Balanced forces cause a change in motion. T/F How do you know this?
Help me, it's due soon!

Balanced forces do not change the motion of an object, Because the forces are the same size and acting in opposite directions.

Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced.
