Give the formula for calculating work done. What is the $SI$ unit of work?

(N/A) The formula for calculating work done is $W = F \times S \times \cos(\theta)$,where $W$ is work,$F$ is the magnitude of the force applied,$S$ is the displacement,and $\theta$ is the angle between the force and displacement vectors. In the simplest case where force is applied in the direction of displacement,the formula is $W = F \times S$.
The $SI$ unit of work is the joule $(J)$,where $1 \ J = 1 \ N \cdot m$.
