Temperature is used as a measurement of the degree of hotness or coldness of an object, and the term heat is used to refer to thermal energy being transferred from a hotter system to a cooler one. The ball continues losing potential energy and gaining kinetic energy until it reaches the bottom of the hill.In a frictionless universe, the ball would continue rolling forever upon reaching the bottom, since it would have only kinetic energy. Thermal energy transfers occur in three ways: through conduction, convection, and radiation. The ball has 18 J of mechanical energy when it leaves her hand.
