Question

When do we say that work is done?

Answer 1

1. Work is said to be done when a force is applied to a body, such that the force causes displacement in the body.
2. We can calculate work by multiplying the force by the displacement of the object.
3. $$\begin{gathered} Workdone=Force\times Displacement\times \cos ofanglebetweenthem \\ W=FS\cos \theta \end{gathered}$$
