Document Summary

Think of it as something than an object or set of objects possess. Work result of force acting through a distance. ) the flow of energy caused by a temperature difference. Heat & work are ways that objects that objects or sets of objects exchange energy. Kinetic energy energy associated with the motion of an object. Thermal energy energy associated with the temperature of an object. A type of of kinetic energy b/c it arises from the motions of atoms or molecules within a substance. Potential energy energy associated with position or composition of object. Chemical energy energy associated with the relative positions of electrons & nuclei in atoms & molecules - a form of potential energy. Some chemical compounds (methane in natural gas) are like a compressed spring - they contain potential energy & a chemical rxn can release the potential energy. Law of conservation of energy states energy can be neither created nor destroyed.
