Work results when a force acts upon an object to cause a displacement (or a motion) or, in some instances, to hinder a motion. 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…
