Detailed explanation-1: -Assertion :Mechanical energy is the sum of macroscopic kinetic and potential energies. Reason: Mechanical energy is that part of total energy which always remain conserved. Reason : Potential energy is always negative and if it is greater than kinetic energy total mechanical energy will be negative.

Detailed explanation-2: -The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy. This sum is simply referred to as the total mechanical energy (abbreviated TME).

Detailed explanation-3: -The total mechanical energy of a system is the sum of the total kinetic energy and total potential energy.

Detailed explanation-4: -mechanical energy, sum of the kinetic energy, or energy of motion, and the potential energy, or energy stored in a system by reason of the position of its parts.

Detailed explanation-5: -The sum of potential and kinetic energies of a body is called its mechanical energy.
