How Do Rockets Work?

A rocket is basically a vehicle that uses Newton’s Third Law to send things into space. Rockets are filled with fuel and when that fuel is lighted on fire, it produces lots of smoke and hot gas. That is actually what sends a rocket into space. According to Newton’s Third Law, “For every action, there is an equal and opposite reaction.” That means that when something moves, there is also an opposite reaction of that motion. While the hot gas and smoke are pushing against the ground and the air, the rocket is pushed up. That is how rockets work!
