This is why things get hot when they are rubbed together. Work done against frictional forces acting on an object cause a rise in temperature of the object. Kinetic energy, gravitational potential energy. Gravitational potential energy work done. It can also be stated as the change in kinetic energy or change in potential energy. W = Work Done (Joules, J or newton-metres, Nm) 2000 J of work would have to be done to bring it back to the ground. The work done by the rocket engine is the force or thrust times the upward distance or displacement at some given point or time in its flight. The equation for work done is one that you need to be able to recall and apply: There are different types of work, this one is mechanical work done and we have met electrical work done earlier on in the course. In essence, it is a measure of an energy transferred to or from an object which allows it to be moved. Work done is defined as the amount of force needed to move an object a certain distance.
