Question

$1joule$of work is said to be done when:

Answer 1

1. $1joule\left(J\right)$is the SI unit of work.
2. This is a derived unit.
3. The formula for work $\left(W\right)$is given by

$Work=Force\times Displacment$

4. Substitute $1N$for force and $1m$ for displacement into the above equation.

$$\begin{gathered} Work=1N\times 1m \\ =1J \end{gathered}$$

5. Therefore, $1joule$of work is said to be done when a force of $1Newton$moves an object through a distance of$1meter$ in the direction of the force.
