This physics video tutorial explains how to calculate the contact force between blocks using free body diagrams. It discusses how to determine the amount of force exerted by a block on another block using Newton's Third Law of Motion which states that for every action force, there is an equal but opposite reaction force. This video contains two practice problems of calculating the contact force between two blocks with and without kinetic friction.
