two major forms of energy • energy of motion; the energy an object has as a result of the amount of mass and its speed: • Kinetic Energy = ½ mv2 • energy of position; the energy an object has as a result of its location: • Potential Energy = various forms and formulas • PEgravity = weight x height = mgh = magravityh • Others include ‘elastic’ PE as in springs and chemical energy
Heat? Thermal Energy is the energy due to the temperature of an object; this is actually Kinetic Energy. Hotter objects are made up of particles that are moving more quickly than colder objects. Heat is the energy that flows from hot objects to cold objects
