SUMMARY
The discussion clarifies that when a force of 100N is applied to a box experiencing an equal frictional force of 100N, the net force is zero, resulting in no change in kinetic or gravitational potential energy. This scenario illustrates that while work is defined as the change in energy, no work is done on the box as it maintains constant velocity. The energy expended in overcoming friction is converted into heat rather than contributing to the box's motion. Understanding this principle is crucial for grasping the concept of work in physics.
