Power is the possession of controlling influence. In physics, power is the rate at which work is performed or energy is converted.
Internal energy is defined as the energy associated with the random, disordered motion of molecules................. External Energy is defined as the energy associated with placing the atoms in the control volume (flow work), at the boundary (boundary work) or across the system boundary (shaft work)

work = force x distance time = distance : time power = work : time force = ?
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."

Work is transferred energy that results when a force is applied to a body causing it to be displaced along the line of force.
Power is the possession of controlling influence. In physics, power is the rate at which work is performed or energy is converted.
Work is the transfer of energy. It is performed when a force causes an object to be displaced causing the object to be moved in the direction of the force. Work = force x distance.
Power is the rate of performing work on an object. Mathematically, power = work divided by time =force x distance divided by time.
In physics, velocity is defined as the rate of change of position
In physics, Power is the amount of work done in a given amount of time. (Note: Work, in the scientific sense, is the amount of force multiplied by vertical distance traveled.)
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.
The term "work", as used in physics, is a transfer of mechanical energy - defined (in the simplest case) as the product of a force times a distance over which the force acts.
The word 'work' in physics is defined as the transfer of energy from one material body to another. It is a body's displacement in space caused by an external force resulting in motion. If a force is applied but there is no displacement or motion, then no work is done. Also work is not done if a force is applied perpendicular to the body's displacement. Work is expressed in units such as joules or foot-pounds.
