Internal Energy
In this video Paul Andersen explains how the internal energy of a system can change as the internal structure of the system changes. An object model will not be able to account for the restoring forces and so a system model must be used....

Heat
In this video Paul Andersen explains how heat is the movement of energy from an object with a higher temperature to an object with lower temperature. Heat transfer can occur through conduction, convection, and radiation.
