Work is said to be done when a constant force applied on a body displaces it to a certain length. Mathematically, WORK DONE = Force × displacement (If we consider the displacement in the same direction of the force)
Force at an angleEdit
When we apply some force on a body at certain angle then the work is given by:- W.D. = Fscosθ
F is force applied s is displacement θ is the angle with the direction of displacement
Energy is the capability to do work.
