Kinetics, or particle kinetics as it is particularly considered here, deals with the causes of motion. It includes studies of types and cases of force, concepts of force including Newton's laws of motion, momentum, and mass. |
|
Common examples include constant forces, simple harmonic motion, and circular motion. Particular forces such as free fall and projectile motion, effects of electrical and magnetic forces, forces of thermal change, and surface forces such as frictional and viscous forces are also sometimes included.
Force is the subject of Newton's three laws of motion.
Momentum is the product of mass and velocity, and is an important quantity in kinetics. Another quantity, impulse, is defined as change in momentum.
Mass is usually described using a simple scalar variable. The mass of a particle is considered to be concentrated at the point of its location. The product of mass and position is only significant when multiple particles are being considered.

History This subject was not well understood in prehistory, antiquity or classical and medieval times. It has been better developed in modern times, through the 16th century, 17th century, 18th century, 19th century, and 20th century. Its future is obscure |

Sociology including social structure and change, communities, and peoples may also be useful. Institutions including families, education, economics, government, and religion are indirectly connected. Culture may be useful.Behavioral culture including customs, occupations, recreation and entertainment and cultural events can also be considered. Conceptual culture including language, graphic arts, literature, mathematics, applied science, and philosophy is useful. Material culture may be useful. |
|
|
Anthropology including particular groups, human geography, human ecology, physical anthropology, demography, and social foundations is minimally useful. |
|
Personal studiesBiography can be examined. |
|
|
Psychology including social psychology, personality, mental disorders, developmental psychology, behavior patterns, mind, and behavioral elements has to do with observations in kinetics. The human body including form and appearance, life cycle, disease, body functions, and body systems is somewhat connected. |

|
Other Science Biology including biohistory, ecology, systematics, organism biology, cell biology, and molecular biology may also suggest applications. Earth science including geohistory, physical geography, atmospheric science, hydrospheric science,and geology also suggests applications. Astronomy including cosmology, galactic astronomy, stellar astronomy, and local astronomy also suggests applications. Chemistry including chemical systems, changes and reactions, and substances is often the source of interesting problems in mechanical kinetics. |

|
The structure of matter, quantum physics, relativity, electromagnetism, and thermodynamics principally demonstrate applications. It is applied to the study of gravitation, nonrigid mechanics, and rigid body mechanics including dymamic systems, static systems, rotational dynamics, and rigid body description and motion. Kinetics is applied to the study of particle systems including simplified mechanical systems, particle interaction, and system properties, and to energetics including power, energy, and work. It depends heavily on kinematics and types and cases of motion, acceleration, velocity, and position. It uses particle description a little bit. |
