Quizplus · Accepted Answer

The total energy of an object in motion, especially in contexts like pendulums or objects in gravitational fields, remains constant if we ignore air resistance and friction. This is because the total energy is the sum of kinetic energy and potential energy, which convert into each other without loss in an ideal system.
