1 Adding heat energy increases the motion of molecules. 2  Removing heat energy, or cooling, decreases the motion of molecules. 3  If heat is added to a solid, the molecules can move fast enough to change from a solid to a liquid.
In this project, you will be studying kinetic friction (also called sliding friction). When two objects are moving relative to one another, kinetic friction converts some of the kinetic energy of that motion into heat. You can feel the heat of kinetic friction if you rub your hands together. The same thing happens when two objects are sliding past one another-for example, when you push a box across the floor. Part of the energy of your pushing moves the box, and part of the energy is lost to kinetic friction.
