In physics, mechanical energy describes the sum of the potential and kinetic energies present in the components of a mechanical system . Mechanical energy is energy associated with the movement of an object or its position, the ability to perform mechanical work [1] [2] ; it is the energy of movement and the interaction that accompanies it.

Conservation of mechanical energy
The law of conservation of mechanical energy states that in an isolated system, where only conservative forces act, the total mechanical energy is conserved [3] .
Difference from other types of energy
Classification of energy according to various "types" often corresponds to the boundaries of research areas in the natural sciences.
- Chemical energy is a type of potential energy stored in chemical bonds . Studied in chemistry .
- Nuclear energy - energy stored in the interactions of particles in an atomic nucleus . Studied in nuclear physics .
- Electromagnetic energy - in the form of electric charges, magnetic fields and photons . Studied in the theory of electromagnetism .
- Various forms of energy in quantum mechanics , for example, the energy levels of electrons in an atom.
