Energy transfer

The most common forms of energy is c energy, p energy, k energy, e energy and h energy.

Not so common forms of energy are l energy, e r, s and n energy.

Work is done when a .

work = x

The unit of work is the (J).

joules = x

power = /

The unit of power is the (W). 1 W = 1 /. 1 kW = 10^ W. 1 mW = 10^ W.

The principle of conservation of energy states:
cannot be or ; it is always .

efficiency = (/) x
