WebThermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred … WebEnergy is a key principle in physics, as it allows work to be done. The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency.
