The term "radiation" refers to hot materials inside the Earth rising towards Earth's surface, cooling, and sinking back down.

As the temperature decreases, the atoms lose energy. The atoms begin to move slower. They are held together by attractive forces, but are still able to slide past each other.

Three objects having the same mass begin at the same height, and all move down the same vertical distance H. One falls straight down, one slides down a frictionless inclined plane, and one swings on the end of of a string.
