KIDS TRIVIA

Detailed explanation-1: -Since there is no air and space, rockets need to take oxygen with them into space. Inside the rocket’s engine, fuel and oxidizers are ignited in the combustion chamber, creating hot, expanding gases. That gas has pressure, and it pushes harder against the top of the rocket than the bottom, making it go up or forward.

Detailed explanation-2: -As opposed to an airplane engine, which operates within the atmosphere and thus can take in air to combine with fuel for its combustion reaction, a rocket needs to be able to operate in the emptiness of space, where there’s no oxygen. Accordingly, rockets have to carry not just fuel, but also their own oxygen supply.

Detailed explanation-3: -The simple answer is that a rocket moves by pushing on the gas that flame out from its engines. Even though it seems impossible for a massive rocket to move by only venting gas, it’s the simple scientific truth, based on Newton’s third law of motion: for every action in nature there is an equal and opposite reaction.
