Answer:
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.
[tex]W=Fd\ cos\ \theta[/tex]
[tex]\theta[/tex] is the angle between F and d
When the force and displacement are in same direction then [tex]\theta=0[/tex]. It gives W = F. d
When the force and displacement are perpendicular to each other, [tex]\theta=90[/tex]. It gives W = 0
Similarly, When force and displacement are in opposite direction, [tex]\theta=180[/tex]. It gives W = - F. d
So, the correct option is (D) '' W =Fd ''
