Rocket

A rocket (Italian rocchetta‚ "little fuse") is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space.

In fact, rockets work more efficiently in space than in an atmosphere. Multi-stage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, and/or gravity.

Rockets for military and recreational uses date back to at least 13th century China. Significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology for the Space Age, including setting foot on the moon. Rockets are now used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight, and space exploration.

Rocket League

Rocket League is a physics-based vehicle soccer video game developed and published by Psyonix, released for Microsoft Windows and PlayStation 4 on July 7, 2015, with versions for OS X, Linux, and Xbox One also in development. It is a sequel to 2008's Supersonic Acrobatic Rocket-Powered Battle-Cars, and features single-player and multiplayer modes which can be played both locally and online, including cross-platform play between the PlayStation 4 and Microsoft Windows versions.

Gameplay

Rocket League's gameplay is largely the same as that of its predecessor Supersonic Acrobatic Rocket-Powered Battle-Cars. Players control a rocket-powered car and use it to hit a ball that is much larger than the cars towards the other team's goal area to score points, in a way that resembles a soccer game, with elements reminiscent of a demolition derby. Players' cars have the ability to jump to hit the ball while in mid-air. The players can also pick up a speed boost by passing their cars over marked spaces on the field, enabling them to quickly cross the field, use the added momentum to hit the ball, or ram into another player's car to destroy it; in the latter case, the destroyed car respawns moments later. A player may also utilize boost when in the air to propel themselves forward in flight, allowing players to hit the ball in the air.
