Kinetic art

Power Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational the energy due to vibrational motionrotational the energy due to rotational motionand translational the energy due to motion from one location to another. To keep matters simple, we will focus upon translational kinetic energy.

Most projectile weapons use the compression or expansion of gases as their motive force. Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions.

Light-gas guns use a combination of these mechanisms. Railguns utilize electromagnetic fields to provide a constant acceleration along the entire length of the device, greatly increasing the muzzle velocity.

Some projectiles provide propulsion during flight by means of a rocket engine or jet engine. In military terminology, a rocket is unguided, while a missile is guided.


Note the two meanings of "rocket" weapon and engine: An explosion, whether or not by a weapon, causes the debris to act as multiple high velocity projectiles. An explosive weapon, or device may also be designed to produce many high velocity projectiles by the break-up of its casing, these are correctly termed fragments.

Delivery projectiles[ edit ] Many projectiles, e. Aside from explosive payload, a projectile can be designed to cause special damage, e. See pitchingbowling. Kinetic energy penetratorTerminal ballistics — Hypervelocityand Exoatmospheric Kill Vehicle A projectile that does not contain an explosive charge or any other kind of payload is termed a kinetic projectile, kinetic energy weapon, kinetic energy warhead, kinetic warhead or kinetic penetrator.

Typical kinetic energy weapons are blunt projectiles such as rocks and round shotspointed ones such as arrowsand somewhat pointed ones such as bullets. Among projectiles that do not contain explosives are those launched from railgunscoilgunsand mass driversas well as kinetic energy penetrators.

All of these weapons work by attaining a high muzzle velocityor initial velocity, generally up to hypervelocityand collide with their targets, converting their kinetic energy into destructive shock waves and heat.

Other types of kinetic weapons are accelerated over time by a rocket engine, or by gravity. In either case, it is the kinetic energy of the projectile that destroys its target.

Some kinetic weapons for targeting objects in spaceflight are anti-satellite weapons and anti-ballistic missiles. Since in order to reach an object in orbit it is necessary to attain an extremely high velocity, their released kinetic energy alone is enough to destroy their target; explosives are not necessary.

This saves costly weight and there is no detonation to be precisely timed. This method, however, requires direct contact with the target, which requires a more accurate trajectory.


Some hit-to-kill warheads are additionally equipped with an explosive directional warhead to enhance the kill probability e. Israeli Arrow missile or U.

A kinetic projectile can also be dropped from aircraft. This is applied by replacing the explosives of a regular bomb with a non-explosive material e.

It is also applied for training the act of dropping a bomb with explosives. A Prompt Global Strike may use a kinetic weapon. A kinetic bombardment may involve a projectile dropped from Earth orbit. A hypothetical kinetic weapon that travels at a significant fraction of the speed of light, usually found in science fiction, is termed a relativistic kill vehicle RKV.

Some projectiles stay connected by a cable to the launch equipment after launching it:Bits and Pieces - Magnificent Jupiter Two-Way Giant 22 Inch Diameter Wind Spinner - Multicolor Kinetic Garden Windspinner - Decorative Lawn Ornament Wind Mill - Unique Outdoor Lawn and Garden Décor.

Kinetic art or Kinetic sculpture is a movement in sculpture, considered to have started from the period. Each kinetic sculpture, clock, and machine aims to meticulously blend art with engineering. Carefully crafted woodworking plans are available for purchase and download.

In visual art, the term kinetic art, derived from the Greek word kinesis, refers to works that incorporate real or apparent explores how things look when they move, so in its widest definition, kinetic art embraces a huge number of different art forms, as well as media types and styles.
