Zrak se giblje v eno smer, balon pa v nasprotno. Rakete delujejo na podoben na\u010din. Izpu\u0161ni plini, ki z visoko hitrostjo izhajajo iz \u0161obe motorja, potiskajo raketo naprej.<\/p>\n<\/div>\n<p>Ve\u010dina sodobnih nosilnih raket, kot je evropska Ariane 5, je zelo zapletena in ob vzletu tehta ve\u010d sto ton. Ve\u010dino te te\u017ee predstavlja gorivo, na primer teko\u010di vodik in teko\u010di kisik.<\/p>\n<p>Rakete potrebujejo ogromno goriva, da premagajo zemeljsko gravitacijo. \u0160ele ko dose\u017eejo hitrost 28 000 km\/h, so dovolj hitre, da vstopijo v orbito.<\/p>\n<p>Ve\u010dina raket je sestavljena iz dveh ali treh stopenj. Ko stopnja porabi vse gorivo, se lo\u010di od preostalega dela rakete, da se znebijo odve\u010dne te\u017ee. Nato pade nazaj (ponavadi v ocean in dale\u010d stran od naseljenih obmo\u010dij) ali zgori v atmosferi.<\/p>\n<p>Velike nosilne rakete pogosto dobijo dodatni zagon z raketami, pritrjenimi na prvo stopnjo. Te lahko uporabljajo trdno ali teko\u010de gorivo. Tudi te se obi\u010dajno zavr\u017eejo.<\/p>","protected":false},"excerpt":{"rendered":"<p>Have you noticed what happens if you let the air out of a balloon?
