conservation of energy
energy is transferred between energy stores
kinetic- anything moving
chemical-anything release energy by a chemical reaction
thermal- any object
gravitational potential- anything in a gravitational field
elastic potential- anything that is stretched
electrostatic- two charges that attract and repel each other
magnetic- two magnets that attract and repel each other
nuclear- atomic nuclei release energy from this store during nuclear reactions
energy can be transferred between stores in 4 main ways:
mechanically- an object moving due to a force acting upon it
electrically- a charge moving through a potential difference e.g charges moving around a circuit
by heating- enegy transferred from a hotter object to a colder one
by radiation- enrrgy transferred by light or sound waves
Law of conservation of energy
enegy can be stored, transferred between stores, and…
