Rocket Engines Explained [IN UNDER 3 MINUTES || AN ILLUSTRATION OF NEWTON'S THIRD LAW]

How do rocket engines work? What makes them work in a vacuum?

In this video, I compare a rocket engine to a balloon, an object we are much more familiar with. As gas escapes one way, a force is applied the other way.

This simple comparison illustrates the basic physics behind Newton's 3rd Law of Motion. Understanding this law is critical to understanding how rocket engines, and many other propulsion systems, work.

Bro, keep this videos coming please. You know how to explain this stuff 😂😅😂

found the channel from the Faraday Cage video, usually I don't comment on videos, but you surely deserve A LOT more recognition, keep it up!

¨As gas escapes one way, a force is applied the other way. ¨
That reaction force is an immaterial force and an immaterial force could be deemed a spiritual force, but I like to say, rockets work on the principle of will power.
We know, that gas escapes ONE WAY and gas is a material made of molecules, but there is no material force going the other way to push the rocket in opposite direction, so it must be an immaterial force pushing it forward.

So balloons push on the atmosphere but rockets don't? Ok 😂

Not trying to attract a bunch of flat earthers. Just trying to understand why it is that the balloon is not pushing off of other air molecules around it. Is the water in the hose not doing the same thing?

Here is my example to help one understand how rockets work.
Let's consider a rocket engine running on earth in atmosphere before we discuss a vacuum.
Let's use a space shuttle main engine as an example.
So, when an SSME is running, here on earth, in sea-level atmosphere (14.5 PSI)
1 - Does the exhaust gas get "accelerated" as it leaves the rocket nozzle?
2 - Does the exhaust gas have "Mass"?
3 - Can "Mass" Be "Accelerated" without a "force"?
(Or is a force required to accelerate mass?)

However, this lecture requires some participation from the class.
Anyone?
