SUMMARY
The work-kinetic energy theorem states that the work done on an object is equal to the change in its mechanical energy, represented by the equation W = ΔK + ΔU. In the scenario of raising a ball vertically at a constant speed, no net work is done on the ball, as its kinetic energy remains constant. However, the potential energy increases due to the elevation gain, indicating that the total energy is not conserved in this context. This highlights the limitations of the work-kinetic energy theorem, which is applicable only under specific conditions.
