Physics is the scientific study of the basic structure and behavior of nature in terms of matter, energy, and forces and how they relate within the framework of space and time. All natural entities whether microscopic or macroscopic, animate or inanimate, are treated within the scientific discipline of physics.
The word you're looking for is... Fusion
Based on the etymology of the word, physics can be defined in the following way: "Physics is the episteme of Nature, and Nature (Φύσις) is the phenomenon of spontaneous appearance and evolution." See Georgios Choudalakis' work on this at: http://www.mit.edu/~gchouda/miscellanea/physics/Physics_etymology.pdfBased on the etymology of the word, physics can be defined in the following way: "Physics is the episteme of Nature, and Nature (Φύσις) is the phenomenon of spontaneous appearance and evolution."

fire
Space is the three-dimensional fabric containing all matter, energy, and forces.
The unit of weight in physics is the Newton (N). It is defined as the force exerted on an object due to gravity.
Fusion is the process in which nuclei combine to form more massive nuclei in physics.
The SI derived unit of energy is named after James Prescott Joule, an English physicist andbrewer who lived from 1818 to 1889. Joule studied the nature of heat, and discovered itsrelationship to mechanical work. This led to the theory of conservation of energy, whichled to the development of the first law of thermodynamics.

Force times distance
In physics, work is defined as the transfer of energy that occurs when a force is applied to an object and causes it to move in the direction of the force.
In physics, velocity is defined as the rate of change of position
The unit for work in physics is the joule (J). Work is defined as the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
