How/Why does Heat create kinetic energy in molecules of an object?
If a boulder fells off a cliffit would lose all its potential energy when it lost its height, and it would losee all its kinetic energy when it hit the ground and stopped moving. If energy is always conserved and can never be created or destroyed, where d
