Question

Define the term 'work'. Write the formula for the work done on a body when a force acts on the body in the direction of its displacement. Give the meaning of each symbol which occurs in the formula.

Answer 1

In relation to physics, if a body is displaced by a force in the direction of force, the work is said to be done. In simple words, work is something you do when you use a force to displace any object in the direction of the force.

The mathematical formula to calculate the work done is given by the product of displacement produced in a body and the force acting on it in the direction of the displacement. i.e. $W=F\times s$

(Where 'W' is the work done, 's' is the displacement and 'F' is the force in the direction of displacement of the body)
