Answer:
Mechanical energy is the energy of potential and kinetic energy i.e sum of potential and kinetic energy.
Step-by-step explanation:
Mechanical energy is the energy posses by an object which enable it to work due to it's potion or movement.
Mechanical energy can be inform of potential energy( energy stored or due to object position) or kinetic energy( object in motion).
Mechanical energy is the sum of potential energy and kinetic energy. This energy is associated with object's position or motion.
