Give an example of an unbalanced forces acting on an object

Forces that are equal in size but opposite in direction are called balanced forces. Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force

An unbalanced foreces a group of people playing tug of war
