A force is a push or a pull. A forcecan give energy to an object causing the object to start moving, stop moving, or change its motion. Forces occur in pairs and can be either balanced orunbalanced. Balanced forces do not cause a change in motion. They are equal in size and opposite in direction.
Whereas in Unbalanced force these aren't equal..
