1. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. It is the energy associated with the motion and position of an object.

2. The two kinds of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy of motion, an object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Potential energy is the stored energy in an object due to its position or arrangement.

3. The law of conservation of energy states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another. This means that the total amount of energy in a closed system remains constant.

4. The law of conservation of mechanical energy states that the total mechanical energy in a closed system—i.e., one that does not exchange any matter with the outside and is not acted on by outside forces—is constant if the only forces that do work are conservative forces. In other words, in any given system, the sum of the potential energy and the kinetic energy is a constant, provided that no non-conservative forces (like friction or air resistance) are doing work.
