identify the 9 types of energy
electrical,light,sound,kinetic,nuclear,thermal,gravitational potential,elastic potential,chemical
1 of 5
conservation of energy
energy can be transferred usefully from one form to another, stored or dissipated- but it can never be created or destroyed
2 of 5
what do you need to know about useful energy
energy is only useful when it can be converted from one form to another
3 of 5
how do you calculate efficiency
useful energy out/ total energy in
4 of 5
what do you need to know about 100% efficency
no device is 100% efficient the wasted energy is usually spread out as heat
