Simple analogy: you are driving down a city street, 25 miles per hour, and your spouse shouts "Turn here!". So you make a sharp right angle turn, squealing on two wheels, and everything gets flung to the side.
Later you are zipping down the freeway, 75 mph, and take an offramp to another freeway, also a right angle turn. But nothing gets flung about, you barely feel any centrifugal force in spite of 3x greater speed! The reason? Much larger turning radius.

[Wolfie]

Math is the Achilles heel of every Flat Earther I have encountered.

[WillRennar]

"I should feel more turn from something that takes 24 hours to go around once than I do on something that takes 3 seconds to go around once!" ~How Barry's arguments came off to me.

[sineout]

Also worth noting is that when you do the maths to figure out how fast it has to turn to fully counteract gravity, it works out to a rotation period of about 90 minutes and linear speed of about 28, 000 kmh (17, 500 mph).
Sound familiar? It should; that's low-earth orbit speed and that's no coincidence. Flerfers who bring up centrifugal force throwing things off as an argument think they're woke and they're pointing out something that's a killer for the globe. On the contrary: it's been known, understood, calculated, measured and confirmed for a very long time. Intelligent people have been using it to put stuff in orbit for nearly 65 years.

Everytime I hear someone going on about the earth spinning at "1000 mph" I want to ask them to find me a grinder that runs at 250mph. Or a lathe that runs at 150mph.

The use of lbs in the mass category saddens me

[BBG]

When you said is everyone with me so far all I could think of was the stupid look on the faces of all those flat earthers as they actually attempt to grasp the math. Another great video GS.

[treadingtheboards]

Maybe ask Barry how much tangential force he would feel if the wall of death only rotated once every 24 hours.
Great explanation, for me, it was easily understood.

[Sparky-vjdq]

Excellent! Flat Earthers: People who are over-impressed by large numbers which don't matter and under-impressed by small numbers which do matter.

[thephantomeagle]

Is it wrong that I just started laughing really hard at that warning?

[abdobelbida]

And this is why we don't use mph to measure SPIN, get it barry?

[paulbarratt]

Flat Earther: It's not fair to use maths. You can't feel maths so it doesn't count.
Science: But all science needs maths.
Flat Earther: OK. I used maths and it says you're wrong.
Science: *Lists every error made in flat earth "maths" and teaches flat earther how to do it properly.*
Flat Earther: It's too complicated. It has to be easy or it's not right. *sulks*

I’m sure I’m not alone in absolutely loving this series G.
You’ve really been doing an outstanding job with this. I really liked this one in particular. Please keep it going.

[Martial-Mat]

I didn't know, but now I do. That was fantastically useful and extremely interesting. Thank you.

[mrandrat]

Me: How fast is the engine idling?
Flerf: 1000 mph....

[AllanFolm]

Also, the frame of reference for humans are relative to the surface of Earth, so the greater picture isn't something we can relate to easity.

[acefox]

Nice video Jerry! These concise nuggets are just what’s needed for the flerfers who ask the same questions over and over.

Also loved the rotoscope animation filter at the beginning. Very cool!

[janrdoh]

Yeah! I saw Barry leaving the room right when GS said "let's do the math".

[icansciencethat]

I'd like to add that you cannot feel gravity while you're in freefall... think of weightlessness on the space station. The Earth is in freefall around the Sun, so no matter what acceleration that is (very tiny), it feels neutral because we're in freefall.

Edit: Cool filter!

In Perth Australia, as a kid I'd go to the Royal Show every year and have a few rides on the "Western Roundup". I don't believe I would have gotten on it if it was called the Wall of Death!!
Awesome video (as always!)
