Question 2
Write an expression for the work done when a force is acting on an object in the direction of its displacement.

Answer 1

When a force $F$ displaces a body through a distance $S$ in the direction of the applied force, then the work done $W$ on the body is given by the expression:
Work done = $Force\times Displacement$
$\Rightarrow$$W=F\times S$
