Today I want to take a moment to talk about the force generated by two opposing objects, which in turn, can and does result in what we call “movement”.
Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
Now, in such regard the thing to remember is this. The force that causes the ball to push back in both situations is resistance. So, the question then would be to ask what is causing the “resistance” to occur between the girl and the ball. The obvious answer here is the atmosphere. As the ball is leaving the girl’s hands, the ball is pressing against the particles of air that surround both it and the girl in the room. The more particles that exist in a given space, the denser that atmosphere is surrounding the two objects… thus, the stronger the resistance. If we removed the atmosphere, the ball would experience zero resistance. As a result the ball would not “push back”, generating friction on the girl’s feet.
Secondly, I want to raise the question of positioning. Consider this; you take away the atmospheric pressure, removing and push back the ball might exert. But also, lift the girl’s roller skates off of the floor as well. At that point you have two objects pushing against one another with zero force exerted between them while simultaneously removing the platform by which the first object might have traveled in an opposing direction. Therefore, what allows the girl to travel in regard to Newton’s third law is atmospheric pressure and a platform of travel.
Make sense? This is what brings me to the title of this blog post. Two days ago in February 15th, the Progress MS-08 docked with the international space station for it’ resupply of the station.
My question is this; what is Progress MS-08 pushing against? And, what is the Progress MS-08’s platform of travel?
You see, there is this thing called “the vacuum of space“.
A vacuum is space devoid of matter. The word stems from the Latin adjective vacuus for “vacant” or “void“. An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure or devoid of pressure entirely.
Now, what people like SpaceX and NASA will suggest is that rockets operate in the vacuum of space by propelling gases in one direction to create an opposite and equal force on the craft. There is no need for air (atmosphere) for those gases to push against thanks to Newton’s third law of motion. You can read that article here explaining how Newton’s third law apparently work’s in the vacuum of space.
I’m sorry, but how absurd can we honestly get? The thing that causes Newton’s third law to work is the atmospheric resistance. without said resistance, no external force would be experienced. It is honestly that simple.
Let’s ask Neil.
Oh, wait… we are forgetting one thing; atmospheric resistance. There is, after all, an atmosphere inside the international space station. At least I would hope. Wouldn’t be able to breath otherwise, right?
I rest my case. Space is fake. But hey, don’t take my word for it. I clearly am… after all, just an ignorant Christian that still believes in silly things like creation, talking snakes, and an earth yielding plant-life that existed 3 days before the sun and moon were even on the scene.
Clearly, this pre-production and post-production footage of the ISS doesn’t speak for itself either.
Anyway, rant over.
