Now let's use the conservation of energy to solve for the speed v at the bottom of the incline. At the top of the incline, the body is at rest, and its energy is all potential and equal to Mgh.

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.)

The direction of the rolling frictional force is always opposite the direction of motion of the axis of the wheel.
