Force And Motion Unit Test: Quiz!

Force is a push or pull working on an object or energy as an element of physical action or movement. This motion happens when two entities are in contact. The association of force and motion can be mathematically expressed. This quiz requires that you know what the force of attraction between two objects is and what force resists the movement of one surface against another. This quiz will help you understand the relationship between force and motion.
