Question

what is the si unit of work

Answer 1

Hi Vansh,

The magnitude of work done is given by the product of force (F) and displacement (S).

Work = Force × Displacement

To obtain the unit of work, we substitute the SI units of force, i.e. N, and distance, i.e. m, in the equation of work.

W = N × m

= Nm

Hence, the unit of work is Nm. In the honour of physicist James P. Joule, the SI unit of work is written as Joule (J).

Hence, 1 J = 1 Nm

1 Joule is defined as the amount of work done by a unit force such that it displaces an object by a distance of 1 m.

Hope you got the answer to your question,

Cheers!!
