Joule is the unit of energy and work done is jule/second.

i.e watt is correct answer.

Nikhil said:   8 years ago
Simple answer is that;

Kg for weight.

Metre for distance.

Therefore work is joule.

Anila said:   9 years ago
Force = Newton and Distance = Meter.

Therefore N*m = Joules.

Rak said:   10 years ago
Obviously work is always expressed in 'Joule'.

Hemant said:   1 decade ago
Since work done is always stored as energy or equivalent to energy used work done will have same unit as that of energy which is joule.

Kg for weight, while.. Meter for distance, and. Watts for current measuring. So it should be "joule".

Work Done = Force per unit length

Units of force is: Newton
Units of length is: meter

Newton/meter can be called as JOULE.

Units of Work Done is: N/m = JOULES

Piyush said:   1 decade ago
SI unit of force is newton(N) and s.i. unit of displacement is meter(m).

Work done = Force*Displacement

So, when we take product of both s.i. units we get Nm

Nm = joule(j).

i joule = newton.metre
work done=force * distance
joule is an international unit of work done

Naman said:   1 decade ago
Since work= force*displacement
and, unit of force= newton(n)
unit of displacement(distance)= metere(m)
hence, unit of work= newton(n)*metere(m)
which is joule(j)
