walking

mohamed

336 views

walking is a simple action that many of us engage in everyday, yet i bet only few understand that the action is a blend of numerous laws of physics put into motion. when we walk, we push the ground backwards, and the ground pushes us forward in accordance with newton's 3rd law (for every force there is an equal and opposite force), in fact we walk only due to presence of frictional force, we do work against friction to walk. such friction allows us to apply the forces to the ground in order to advance ourselves in walking.
