Equations Flashcards
Kinetic energy store
Kinetic energy store = 0.5 X mass X voltage2
Gravitational potential energy store
Gravitational potential energy store= mass X Gravitational field strength X Height
1 Power
Power = energy transferred Divided by time
2 Power
Power=Work done divided by time
Efficiency
Efficiency=Useful energy output
