GENERAL KNOWLEDGE

Detailed explanation-1: -Mechanical energy (kinetic energy or potential energy) is the energy of either an object in motion or the energy that is stored in objects by their position. Mechanical energy is also a driver of renewable energy. Many forms of renewable energy rely on mechanical energy to adequately produce power or convert energy.

Detailed explanation-2: -Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force.

Detailed explanation-3: -Mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. For example, a moving vehicle possesses mechanical energy in the form of kinetic energy, a compressed spring possesses mechanical energy in the form of potential energy.

Detailed explanation-4: -Thus, the conservation of mechanical energy is valid only when the external and non-conservative forces on the system are zero.

Detailed explanation-5: -Mechanical energy is the total amount of kinetic energy and potential energy of an object that is used to do a specific work. Mechanical energy can also be defined as the energy of an element due to its position or motion or both.
