The physics of propulsion does not require an atmosphere
In short: Many believe rockets need air to push against, but the reality of orbital mechanics is far more elegant. This video explains how propulsion works in a vacuum and why space travel is possible.
The core principle of rocket flight relies on Newton's Third Law of Motion: for every action, there is an equal and opposite reaction. Because a rocket generates thrust by expelling mass at high velocity out of a nozzle, it does not need to push against the surrounding environment.
This mechanism allows spacecraft to accelerate in the vacuum of space where no air molecules exist. The video explores these fundamental physics to clarify how we break the chains of gravity and achieve orbital flight.
