Question

The expression for work done, when the displacement is in the direction of the force is:

• A. $F\times S$
• B. $0$
• C. $-\frac{F}{S}$
• D. $\frac{F\times S}{2}$

Answer 1

The correct option is A $F\times S$

In this case, the force and the displacement acts along the same direction. So, work done is positive. Therefore, the expression for work done is given as $Workdone=Force\left(F\right)\times Displacement\left(S\right)$.
