Answer:
Consider the example of a man pushing a box across a rough floor at a constant velocity as shown in Figure 1. Since the friction force is non-conservative, the work done is not stored as potential energy. All the work done by the friction force results in a transfer of energy into thermal energy of the box-floor system. This thermal energy flows as heat within the box and floor, ultimately raising the temperature of both of these objects.
