This sentence is the description of the mechanical energy.
In this sense, the mechanical energy of a body or a system is that which is obtained from the speed of its movement (kinetic energy) or its specific position (potential energy), in order to produce a mechanical work.
That is to say: The mechanical energy involves both the kinetic energy and the potential energy (which can be elastic or gravitational, for example).
In addition, it should be noted that mechanical energy is<u> conserved in conservative fields and is a scalar magnitude.</u>
Therefore:
<h2>The sum of potential and kinetic energies in the particles of a substance is called <u>Mechanical Energy</u></h2>
