Please type your __subject__ in the **School Subject** box. Any other words, __including obscure abbreviations__, are likely to delay responses from a teacher who knows that subject well.

The work done is force x distance

The power used is the rate of doing work, i.e. work/time

Note that the word for the unit of force, newton, has a lower case 'n' whereas the symbol has a capital 'N'.

power=work/time=force*distance/time
