Answer:
mechanical energy
Explanation:
the definition of mechanical energy is the sum of an objects kinetic and potential energy
The energy that is the sum of the kinetic and potential energy is mechanical energy. Thus, option A is correct.
The energy can be defined as the ability of an object to do work. The energy is conserved and can be converted from one form to another. The kinetic energy is the energy possessed by the working body, while the potential energy is the energy possesses by the body at rest.
The sum of the kinetic and potential energy gives the cumulative mechanical energy possessed by the body. Thus, option A is correct.
