Question

Quizplus · Accepted Answer

The total mechanical energy of a system is the sum of the kinetic energy and potential energy at any point. This means that as an object moves through space, its total mechanical energy remains constant as long as no external forces act on it. The kinetic energy is the energy of motion, while the potential energy is the energy associated with an object's position or configuration. By summing these energies together, we can calculate the total mechanical energy of the system.
