conservation of energy
energy cannot be created or destroyed
during an energy transfer some energy is always lost as heat to the surroundings (dissipated)

New cards
example - a battery is powering a circuit
chemical energy store is decreasing
3
New cards
example - a diver is falling through the air
gravitational potential energy store is decreasing
4
New cards
