The temperature of the water will then increase. Energy is transferred by heating to the water’s thermal energy store. Heating a material transfers the energy to its thermal energy stores and the temperature increases.Įnergy is transferred to the thermal energy store of the kettle. Radiation: when energy is transferred as electromagnetic waves or as moving subatomic particles.Heating: when energy is transferred from a hotter object to a colder object.Electrically: when a charge is moved through a potential difference.Mechanically: when work is done by a force.The energy stored in the nucleus of an atom.Įnergy can be transferred in the following ways: The energy stored when repelling poles have been pushed closer together or when attracting poles have been pulled further apart. The energy stored when repelling charges have been pushed closer together or when attracting charges have been pulled further apart. The energy store of an object lifted in a gravitational field. The energy stored when an object has been stretched or compressed. All objects have a store of thermal energy. The total kinetic and potential energy of the particles in an object. When an object is stretched or squashed, energy is transferred to its elastic potential energy store.Įlastic potential energy = ½ × spring constant × (extension)² Energy Stores and Systems Energy Stores When an object falls, energy is transferred from the gravitational potential energy store to the kinetic energy store. Gravitational potential energy = mass × gravitational field strength × height When an object is lifted in a gravitational field it has a store of gravitational potential energy.
