Three variables are of importance in this definition - force, displacement, and the extent to which the force causes or hinders the displacement. Each of these three variables finds their way into the equation for work.

 

That equation is:

Work = Force × Displacement

W = F × d

Since the standard metric unit of force is the Newton and.... View More
