Friction is the resistant force that produces heat when 2 object are rubbed together. Velocity is a fancy word for speed. Momentum is another word for speed. Movement is the motion forward, backward or in any direction. it is affected by weight, because the heavier an object is, the more of an affect that gravity has on said object.
