Work done on three different masses

In this movie, you see three masses all with identical forces acting on them. The force on each object remains active until it reaches the end of the distance shown. Even though the smaller masses accelerate more than the larger masses, the same amount of work is done on each object. As a result of the same amount of work being done on each, the kinetic energy (KE) of each object is the same. (remember that...
