How would you calculate an object’s mechanical energy? . a.. add its kinetic and potential energies.. b.. multiply its kinetic and potential energies.. c.. subtract its kinetic energy from its potential energy.. d.. subtract its potential energy from its kinetic energy..

The correct answer among the choices listed is option A. To calculate an object's mechanical energy, you have to add its kinetic and potential energies. Mechanical energy of an object can be the result of its motion and its stored energy therefore the total energy should be the sum of both type of energies.
