Energy conservation with nonconservative forces: When an object is solely under the influence of conservative forces, the sum of its kinetic and potential energies does not change.

Question

Quizplus · Accepted Answer

The conservation of energy principle states that the total energy of an isolated system remains constant. When an object is solely subjected to conservative forces, such as gravitational and elastic, the energy is conserved as the sum of kinetic and potential energies remains constant. However, when nonconservative forces, such as friction or air resistance, are involved, some of the energy is converted into other forms of energy like heat or sound, leading to a decrease in the object's total mechanical energy.
