Which is the correct formula used to calculate work? a w = ld b w = fh c w = lh d w = fd

d work = force times distance ... if force is constant

Work, W =Fd

Explanation:

Work is said to be done when a force is applied on an object in order to create some displacement. The mathematical expression for work done is given as:

W = F. d

Where

F is the applied force

d is the displacement

Work done also depend on the angle between the force and the displacement i. e.

is the angle between F and d

When the force and displacement are in same direction then . It gives W = F. d

When the force and displacement are perpendicular to each other, . It gives W = 0

Similarly, When force and displacement are in opposite direction, . It gives W = - F. d

So, the correct option is (D) '' W =Fd ''
