The kinetic energy of the package increases, indicating that the net work done on the system is positive. (See Example 1.) By using Newton’s second law, and doing some algebra, we can reach an interesting conclusion. Substituting Fnet = ma from Newton’s second law gives Wnet = mad....
Physics - Work and Energy - When acting (applying force), there is a displacement of the point of application in the direction of the force, is known as work.
