In Chapter 7, the work–kinetic energy theorem, W = ∆K, was introduced. This equation states that work done on a system appears as a change in kinetic energy. This is a special- case equation, valid if there are no changes in any other type of energy such as potential or internal. Give some examples in which work is done on a system, but the change in energy of the system is not that of kinetic energy.
