This resistance is a force of friction. Friction opposes relative motion between systems in contact but also allows us to move, a concept that becomes obvious if you try to walk on ice. Friction is a common yet complex force, and its behavior still not completely understood. Still, it is possible to understand the circumstances in which it behaves.

(Ignore the masses of the rope and the pulley and any friction in the pulley.) The mass of box A is 5.0 kg and the mass of box B is 2.0 kg. The force acting to move the system is the weight of box B, and the force resisting the movement is the force of friction between the table and box A.

According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force.

This interaction of the atomic layers causes the object's kinetic energy to be converted to heat bit by bit, so both the object and the floor become hotter as the object slows down. (We'll learn about kinetic energy in Chapter 26.)
