(1)Kinetic energyFrom Wikipedia, the free encyclopedia

The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path. When they start rising, the kinetic energy begins to be converted to gravitational potential energy. The sum of kinetic and potential energy in the system remains constant, ignoring losses to friction.The kinetic energy of an object is the energy which it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.

The speed, and thus the kinetic energy of a single object is frame-dependent (relative): it can take any non-negative value, by choosing a suitable inertial frame of reference. For example, a bullet passing an observer has kinetic energy in the reference frame of this observer, but the same bullet is stationary, and so has zero kinetic energy, from the point of view of an observer moving with the same velocity as the bullet.[2] By contrast, the total kinetic energy of a system of objects cannot be reduced to zero by a suitable choice of the inertial reference frame, unless all the objects have the same velocity. In any other case the total kinetic energy has a non-zero minimum, as no inertial reference frame can be chosen in which all the objects are stationary. This minimum kinetic energy contributes to the system's invariant mass, which is independent of the reference frame.

In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is mv2/2. In relativistic mechanics, this is only a good approximation when v is much less than the speed of light.


(2)Kinetic Awareness From Wikipedia, the free encyclopedia

Kinetic Awareness is a system of bodywork originated by the American choreographer Elaine Summers in the second half of the 20th century, starting in the 1950s.[1][2][3]

The practice is developed through close individual observation of proprioceptive and kinesthetic processes. This practice of heightening self-awareness is also compared to more objective information about anatomy. The resulting awareness is used towards the goal of Kinetic Awareness: to develop one's full individual potential for healthy movement.

Because of its use of hollow rubber balls to achieve deep muscle-relaxation, Kinetic Awareness is also referred to as "The Ball Work".


(3)Kinetic art From Wikipedia, the free encyclopedia

Kinetic art is art that contains moving parts or depends on motion for its effect.[1] The moving parts are generally powered by wind, a motor or the observer. Kinetic art encompasses a wide variety of overlapping techniques and styles. >kinetic art fair



(4)Kinesiology From Wikipedia, the free encyclopedia

This article is about the scientific study of human movement. For the alternative medicine diagnostic and healing technique, see Applied kinesiology.

Kinesiology, also known as human kinetics, is the science of human movement. Please see exercise physiology for the broader subject of physiology related to exercise, a less common use for the term.

In most countries, kinesiology refers to a field of scientific study. In Canada, Kinesiology has been designated a regulated health profession [1] The word comes from the Greek words kinesis (movement) and kinein (to move).

The science of kinesiology addresses the physiological, mechanical, and psychological mechanisms associated with human and animal movement. Applications of kinesiology in human health include the rehabilitation professions, such as physical and occupational therapy, as well as applications in the sport and exercise industries..[2] Individuals who have earned degrees in kinesiology can work in research, the fitness industry, some clinical settings, and in industrial environments.[3] Studies of human and animal motion include measures from motion tracking systems, electrophysiology of muscle and brain activity, various methods for monitoring physiological function, and other behavioral and cognitive research techniques .[4][5]

Kinesiology as described above should not be confused with applied kinesiology, a controversial[6][7][8] chiropractic diagnostic method.[9]
