aleex- he worked as a mathematician
2 Newton-meters
Newton derived Keplars findings from Newton's Theory of Gravity. Thus, newton 'explained' the basis for Keplars findings and extended them.

rate at which work is done
The work done by a machine.
You have done 1 joule of work. Work -FxD= 1Nx1m=1Nm= 1 joule.
Defined as the work done when applying a force of 1 Newton over a distance of 1 Meter.
'Newton' is a form of measurment, named after Sir Isaac Newton.
I found the answer from http://en.wikipedia.org/wiki/Mechanical_work, which says the SI unit for work done is J (joule) or sometime Nm (newton metre)
500 Joule.
