Energetics, or particle energetics as it is particularly considered here, deals with quantities of power, energy, and work.

Power

Power is the rate at which work is done, or the rate of change of energy. P = W/t. This is more useful a concept in rigid body mechanics, and in relationships between mechanics and other branches of physics than it is in simple particle mechanics.

Mechanical Energy

This comes in two forms, potential energy and kinetic energy.

Potential energy may also be present for particular types of motion. For instance, gravitational, electrical and magnetic forces, and spring-like forces are often associated with potential energy.

The change in kinetic energy of a moving body is equal to the work requred to to accelerate it from rest to its velocity. This can be shown to be

E_K = (1/2)*m*v²

Work

Work, in mechanics, is the result of force acting over a distance. In simple terms.

W = F*d. When forces are variable and not directed along the actual path of motion, more complex expressions are required.



History is not closely connected. Prehistory, antiquity, and classical and medieval history are minimally useful. Most of energetics is a product of the modern period, and the future is obscure. Sociology including social structure and change, communities, and peoples will have some connection. Institutions including families, education, economics, government, and religion may be somewhat applicable. Culture including material culture, conceptual culture, and behavioral culture is more directly applicable. Anthropology including particular groups, human geography, human ecology, physical anthropology, demography, and social foundations seem to have very little direct appliation. Personal studies can be connected. Biography can also be connected. Psychology including social psychology, personality, mental disorders, developmental psychology, behavior patterns, mind, and behavioral fundamentals can be connected. Many concepts can be illustrated using the human body, including form and appearance, life cycle, disease, functions, and body systems.
Biology including biohistory, ecology, systematics, organism biology, cell biology, and molecular biology may demonstrate more applications. Earth science including geohistory, physical geography, atmospheric science, hydrospheric science, and geology may also demonstrate applications. Astronomy including cosmology, galactic astronomy, stellar astronomy, and local astronomy demonstrates applications. Chemistry including chemical systems, changes, and subtances has close connections to energetics.	Links to other sites Not yet included.
The structure of matter, quantum physics, and relativity principally demonstrate applications. Electromagnetism including electrostatics, electric current, magnetism, and optics largely illustrate applications. Thermodynamics including nonclassical thermodynamic systems, classical thermodynamic systems, and statistical mechanics is also connected. Gravitation, nonrigid mechanics, and rigid body mechanics principally demonstrate applications. Other aspects of particle mechanics can be considered. Particle systems including simplified mechanical systems, particle systems, and system properties mostly demonstrate applications. Energetics depends heavily on kinetics including types and cases of force, force and Newton's laws, momentum, and mass. It is closely associated with kinematics. Energetics depends indirectly on types and cases of motion, acceleration, and velocity. It has some connection to position. It assumes that particles are being described. particle description.
