Introduction
-
The formula of work
-
-
F = Force applied, units newton (N)
d = Displacement, units meter (M)
W = works, units Joule (J)
One joule equals the amount of work that is done when 1N of force moves an object over a displacement of 1m

-
Classification of work
-
-
No work/Zero work: When the force is acting on the object is perpendicular to the direction of displacement
