Unbalanced forces occur when two or more forces acting on an object do not cancel each other out, causing the object to move.

Front

What is an example of unbalanced forces?

A soccer ball being kicked is an example of unbalanced forces; the force of the kick is greater than the friction from the ground.

Back

The object will not move.

Front
