Physical Energy at Kensington Gardens, London. Physical Energy is a bronze equestrian statue by the English artist George Frederic Watts. Watts was principally a painter, but also worked on sculptures from the 1870s. Physical Energy was first cast in 1902, two years before his death, and was intended to be Watts's memorial to "unknown worth ...
Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
If a system has a definite temperature, then its total energy has three distinguishable components, termed kinetic energy (energy due to the motion of the system as a whole), potential energy (energy resulting from an externally imposed force field), and internal energy. The establishment of the concept of internal energy distinguishes the ...

Energy – in physics, this is an indirectly observed quantity often understood as the ability of a physical system to do work on other physical systems. [ 1 ] [ 2 ] Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert force (a pull or a push) against an object that ...
