This physics video tutorial explains how to solve contact force problems between blocks with kinetic friction and without friction when the system is under constant acceleration by an applied force and when the masses are moving with constant velocity / speed. In some cases, the coefficient of kinetic friction may be provided. This video contains plenty of examples, practice problems and the equations / formulas needed to solve the contact force of block 1 on block 2 and the force exerted on block 3 by block 2 and vice versa. This video focuses a lot on newton's third law of motion which states that for every action force, there is an equal an opposite reaction force. This video also uses newton's second law of motion which equates to the formula net force equals mass times net acceleration.
