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)

The amount of work done per unit of time?
Work done per unit of time is defined as power. In the metric system, this unit is a watt. In the standard system, it is horsepower.
What is the SI unit for work function?
Work done is a measure of expended energy, so the SI unit for work done is the same as for energy - the Joule.
What is power and what is the unit for power?
Power is the rate of use of energy in time. The unit of Energy is joule and the unit of Power is joule/second or Watt.
Potential difference si unit?
VOLT.... the measurement used is work done per unit charge, the symbol is a V same as for a volt.
What is a potential difference and what SI unit is used to measure it?
it is a quantity defined as work done per unit charge.it has same unit as voltage which is volt represented by 'V'.
What is a unit of work and what does it mean?
Joule is a unit of work and energy equals the work to be done
What is the amount of work done per unit time?
Work done per unit time is called power because power is work done divided by time in sec. So per unit time is seconds.
What is The rate at which work is done or the amount of work done in a unit of time is called?
" power "
How much force is done with the work being 10 and distance being 3?
Work is force times displacement (distance). Thus, about 3 work is being done. The unit depends on the unit of the work and distance. If the work unit is Joules, and the distance unit is meters, then the force unit would be Newtons.
Differentiate batween the work done on the body and work done by the body?
note: Work done is = force applied to a body * time taken by the body When we apply a force on to an object such that the object displaced in the direction of force, then some unit of work is done on the body. When a body sets another body into motion by applying a force, in unit time, that body is considered as it had done a unit of work
What is work done per unit time?
Work per unit time is power. It can be thought of as rate of doing work.
What is the unit that measures one joule of work done in one second called?
Watt is the unit that measures one joule of work done in one second.
Why does work done have to be calculated in meters?
It doesn't. (Any unit of force) times (any unit of distance) is a unit of work, and so is any other unit of energy. (By the way . . . 'meters' is not a unit of work.)
Why is the unit of the amount of work done the same as the unit for energy?
Think of "work" as the transfer of certain types of energy.
What is work done per unit of time?
power
