In physics, mechanical
work is the amount of energy transferred by a force acting through a distance. Like energy, it is a scalar
quantity, with SI units of joules. The term work was first coined in the 1830s by the French mathematician
Gaspard-Gustave Coriolis.
- Wikipedia In physics, energy, from energos, "active, working" is a scalar physical quantity that
describes the amount of work that can be performed by a force, an attribute of objects and systems that is subject
to a conservation law. Eight different forms of energy exist to explain all known natural phenomena. These forms
include (but are not limited to) kinetic, potential, thermal, gravitational, sound, light, elastic, and
electromagnetic energy. The forms of energy are often named after a related force.

In physics and thermodynamics, heat is the process of energy transfer from one body or system to another
due to a difference in temperature. In thermodynamics, the quantity TdS is used as a representative measure of the
(inexact) heat differential δQ, which is the absolute temperature of an object multiplied by the differential
quantity of a system's entropy measured at the boundary of the object. -
