energy stores + systems

• energy can be transferred between objects through work done or heat transfer
• energy stores are thermal, kinetic , gravitational potential, elastic potential, chemical, magnetic, electrostatic and nuclear
• when a system changes, energy is transferred into or away from the system.
• energy can be transfered by heat
• energy can be transferred by work done such as forces on an object
• thermal energy is heat energy
• kinetic energy is the energy of a moving object,
• gravitational potential energy is stored when an object is above ground
• elastic potential energy is the energy stored in a stretched spring or elastic object
• chemical energy is the energy stored in the bonds of molecules in a substance
• magnetic energy is the energy stored in the magnetic field lines of a magnet
• electrostatic energy is the energy stored in the electrostatic potential difference between two points in a field
