Guys, the earth is actually flat.

That what is called Joule


Bullet shot with a rifle will have way more potential energy compared to the same bullet discharged without a gun, because gasses actually doing way more "work" inside the barrel by pushing bullet outside due to a difference in pressure in between 2 independent systems.

Tank will take off, but not in the vacuum of space

I'm sure you are familiar with this new toy? Guess what - it has an altitude ceiling - it need something to push against with higher density that of an air.

5 gallon bucket and water hose is the easiest experiment to try at home

Rockets work because of Newton's 3rd law of motion- every action produces an equal and opposite reaction. They shoot fuel out in one direction, and the ship moves in the other. Stand on a skateboard, and throw a bowling ball. It's not the air resistance on the ball that moves you. It's conservation of momentum.

You are disregarding friction....

Hang yourself on the long rope and then do it again with a ball that has the same mass as yourself.

You will move almost exact same distance from equilibrium point.

No, you are wrong again. Same thing would happen. Try it sitting on a swing. In fact, eliminating friction makes the effect more apparent, as would increasing mass. If you did it on a swing, that ball wouldn't drop straight down, it would move in a very calculated way based on it's mass, your mass, and resultant velocity. If the ball was the same mass as you, and you were strong enough to propel yourself to 10mph, the ball would move 10mph in the opposite direction. How do you eplain any motion whatsoever without this law? Air resistance?

Only with gravity (not friction) from a mass dense enough to produce notable pull.
Otherwise it's just a tangled mess of a neck tie in the vacuum of space.

That makes no sense at all. I think you're trying to describe momentum, which is exactly why rockets work in space. It doesn't matter how big or small the mass is, it is still conserved. Fuel is propelled from the spacecraft with the burning of the fuel. It shoots out. It just doesn't disappear when it burns. It still has the same mass. Momentum will be conserved. That's why it's called a law.

We are arguing about the same thing, but in opposition due to different level of education hence indoctrination. I admit that I'm uneducated swine in term of schoolbooks science. It's all works on paper, JT effect is being disregarded for some reason ;) there was that video with a dude, toycar, balloon and a vacuum. Ones I get to my stationary troll machine I'll find that video. Also, there a cool video with a feather and a bowling ball by BBC - in regards to gravity.
