	Using our understanding of Internal Energy, we can minimize Energy dissipation, create better longer lasting batteries, create machines that require less power that can store more energy. Applying our understanding of Internal Energy is our best chance at creating something close to perpetual motion, and maximizing energy output of our systems.

	Internal Energy, ~~as referred to in Intro Physics~~, is energy within a system. When determining the specifics of internal energy it is best to refer to the real system of the interaction, rather than the point-particle system. The system may consist of internal interactions, such as spring interactions and thermal energy transfer. Internal Energy is any energy in the system other than movement of the center of mass.		Internal Energy, simply put, is energy within a system. When determining the specifics of internal energy it is best to refer to the real system of the interaction, rather than the point-particle system. The system may consist of internal interactions, such as spring interactions and thermal energy transfer. Internal Energy is any energy in the system other than movement of the center of mass.
