Question

When the displacement $\left(S\right)$ is in the direction of the force $\left(F\right)$, work done is equal to ______.

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. Work done is calculated by the formula $\mathrm{force}\times \mathrm{displacement}$ or $FS$, where $F$ is the force applied and $S$ is the displacement.

Hence, When the displacement $\left(S\right)$ is in the direction of the force $\left(F\right)$, work done is equal to $\mathrm{force}\times \mathrm{displacement}$ or $FS$
