AI overview

A rocket is an elongated vehicle powered by a rocket engine that expels exhaust at high speed to create thrust, allowing it to fly even in the vacuum of space where there is no air. Rockets matter because they carry all their own fuel and don't need oxygen from the air to operate, making them uniquely capable of reaching space and beyond, unlike jet engines that depend on atmospheric air.

火箭或稱噴射推進器，是一種利用排出物質以製造反作用力（即發動機）推進的飛行器。速度很快，可以用來運載人造衛星、宇宙飛船等；也可以裝上彈頭和制導系統等製成導彈。因火箭機構最早用於發射箭矢上，因此在中文稱為火箭。另外古代将箭頭附上可燃物質並點火的箭矢也叫火箭，但不在本篇的討論範圍內。
