A force is said to do positive work if when applied it has a component in the direction of the displacement of the point of application. Formal Definition of Work Definition of Work. If a force acting on some object moves it by some distance in the same direction in which the force is acting then that is called work.

Our parents work hard to give us a good life. We tend to use the word work to convey our efforts. Work-energy concepts are based on Newtons laws and do not involve any new physical principles.
