Seems unreal. Unless he is pushing with over ~100lbs of force.

There is something on the wall behind for the last part of the video, I suspect some sort of rog.

There is nothing on the wall, you can see as she climbs in. This principal is not new either, used to have a ride in Sydney that spun and your stuck to the walls.

Kind of hard to find, but polyester has a coefficient of static friction of about 0.8. So if he's using his full body weight, he can do this to anyone that: has proper clothing, is well balanced, and he weighs at least 25% more than. Probably should be closer to 40% to account for not using full weight, bad wall contact, etc.

This is the problem with bringing religion into schools, now they're nailing kids to walls.

Plot twist - the wall’s a giant mimic and he’s giving it his annual sacrifice for better fortunes and good crops.

Well either you are right, or literally every website I can find is. Hmm.

10 months ago | Likes 2 Dislikes 0

Almost literally every website is wrong on lift so it's nothing new in physics. Entry level information is based on ease of understanding and practicality, not on the truth. I elaborated here: /gallery/VCzAlXf/comment/2421499503/1

It's very much a thing in physics. Friction Force = Coefficient of Friction * Normal Force

10 months ago | Likes 5 Dislikes 0

That's not a force. If you know any physics, you'd know that.

Saying friction is a force is as fallacious as saying centrifugal force is a force.

10 months ago | Likes 1 Dislikes 9

Explain why.

10 months ago | Likes 4 Dislikes 0

(1/3) Friction is the combined result of real forces and effects, much like centrifugal "force". Some are happening at the molecular level, such as electromagnetic forces; some are happening on a more macro level, like adhesion or "roughness" of surfaces e.g. sandpaper (this part is in academic dispute).

Introductory physics textbooks refer to it as a force in the same way they almost unanimously misdefine lift;

10 months ago | Likes 1 Dislikes 1

(2/3) it's not a well understood subject that only gets MORE complicated the deeper you go, each step making the initial understanding more false.

For the layman, Feynman touches on this VERY briefly https://www.feynmanlectures.caltech.edu/I_12.html#Ch12-S2 but nobody wants to delve into the nature of friction to a layman bc it's complicated even for physicists so we go with simple empirical concepts like "coefficient of friction" which is just the end result, not the actual forces happening.

You throw your backpack down the hallway, and it slows down and stops - that's acceleration caused by a force.
You tilt the desk a little yet it doesn't slide down, that's a force being cancelled by another.
What's probably confusing you is that it doesn't set things in motion on its own - it's reactive. And TBF it's a combined effect from several microscopic forces.

Nearly everything that pops up after a Google search of "what is friction" starts with "Friction is a force."

10 months ago | Likes 8 Dislikes 0

Take an actual physics class (or if you can't/don't wanna, listen to someone who has like here) instead of relying on Google dumbing down concepts for you.

Grammatically, "frictional force" is more appropriate, but saying "friction isn't a force is dead wrong"
