dynamics

Mechanics \Me*chan"ics\, n. [Cf. F. m['e]canique.] That science, or branch of applied mathematics, which treats of the action of forces on bodies.

Note: That part of mechanics which considers the action of forces in producing rest or equilibrium is called statics; that which relates to such action in producing motion is called dynamics. The term mechanics includes the action of forces on all bodies, whether solid, liquid, or gaseous. It is sometimes, however, and formerly was often, used distinctively of solid bodies only: The mechanics of liquid bodies is called also hydrostatics, or hydrodynamics, according as the laws of rest or of motion are considered. The mechanics of gaseous bodies is called also pneumatics. The mechanics of fluids in motion, with special reference to the methods of obtaining from them useful results, constitutes hydraulics.

Animal mechanics (Physiol.), that portion of physiology which has for its object the investigation of the laws of equilibrium and motion in the animal body. The most important mechanical principle is that of the lever, the bones forming the arms of the levers, the contractile muscles the power, the joints the fulcra or points of support, while the weight of the body or of the individual limbs constitutes the weight or resistance.

Applied mechanics, the principles of abstract mechanics applied to human art; also, the practical application of the laws of matter and motion to the construction of machines and structures of all kinds.

orbital mechanics, the principles governing the motion of bodies in orbit around other bodies under gravitational influence, such as artificial Earth satellites.

Dynamics

Dynamics (from Greek δυναμικός dynamikos "powerful", from δύναμις dynamis " power") may refer to:

Dynamics (mechanics)

Dynamics is a branch of applied mathematics (specifically classical mechanics) concerned with the study of forces and torques and their effect on motion, as opposed to kinematics, which studies the motion of objects without reference to its causes. Isaac Newton defined the fundamental physical laws which govern dynamics in physics, especially his second law of motion.

Dynamics (music)

In music, dynamics are instructions in musical notation to the performer about hearing the loudness of a note or phrase. More generally, dynamics may also include other aspects of the execution of a given piece.

Dynamics (album)

Dynamics is the second studio album by American synthpop duo Holy Ghost!. It was released on September 3, 2013 by DFA Records. The album was preceded by the single "Dumb Disco Ideas" on May 14, 2013. The album's cover features the image "Strong in Love" by American painter and sculptor Robert Longo.

Usage examples of "dynamics".

They are like the colossal strides of approaching Fate, and this awfulness is twice raised to a higher power, first by a searching, syncopated phrase in the violins which hovers loweringly over them, and next by a succession of afrighted minor scales ascending crescendo and descending piano, the change in dynamics beginning abruptly as the crest of each terrifying wave is reached.

Extensive research by the Behavioral Science Unit at the FBI academy and in-depth interviews with incarcerated felons who have committed such crimes have provided a vast body of knowledge of common elements, that link crime scene dynamics to specific criminal personality patterns.

There would be a multitude of disputes, often intentionally misinterpreted, to resolve territorial and jurisdictional differences that were already caught up in and molded by the dynamics of orbiting planets, and their satellites and connecting space-ways.
