So this way that the unit have to be Nm. However, once I researched on Google, a lot of of human being were saying the the unit is J.

You are watching: What is the unit for work

The unit you have to use for occupational done and energy is the joule (J) i m sorry is indeed the same as the newton metre (N m).

There is one more physical amount which is the product the force and also distance and that is torque or moment of a force.The unit you must use for torque is the newton metre (Nm) and also not the joule.

Naming the units of work done and also torque in different ways helps to emphasis the truth that work done and torque describe two different physical quantities although the definitions of both quantities have actually the product that force and distance in them.

\$ extwork done= vec m force ,cdot, vec m displacement \$ and also \$vec m torque= vec m force , imes, vec m displacement \$

J (joule) is a obtained unit for power (or occupational done) called after the physicist James Joule. Since \$W = F.d\$, we have 1 J=1 Nm. We can additionally express in state of basic SI units, yielding us

1 J = 1 kg m\$^2\$s\$^-2\$.

J (joule) is the SI unit that \$work\$ which is same to N m. It"s a acquired unit of work and the name is favored in honor of James Joule who is pretty renowned for his work-related in Thermodynamics.
