In what direction does a large mass and small mass object move when affected by unbalanced forces?

An object's motion can be changed by unbalanced forces. Balanced forces do not change the motion of an object.

The motion of an object acted on by a force depends partly on the strength of the push or pull. The stronger the push or pull, the faster the object will move. For example, the father in the picture below is pushing his daughter in a swing. When he uses more force to push, the swing moves higher.
