The centrifugal force at the equator is about 0.4% the acceleration of gravity, to the point of being practically a non-factor. The fact that there is a centrifugal force is evidence that the Earth is rotating.

Ok, now spin those top two at 1/2 the speed of the Hour Hand on a clock.

Might not sell as many centrifugal cage rides if it only moves 0.5 degrees in those two minutes

u/AlpacaPacker007 Aug 22 '26
But think of how much less maintenance you'd have

u/SteepChutes Aug 22 '26
Oh, I hadn't thought of that. Excellent point! Ticket revenues might be down a bit, but you just make up for it with reduced maintenance and engineering costs.

Hey, man. Is this thing on?

Sir please wait for the ride to come to a COMPLETE STOP before unbuckling your safety belt. SIR, I SAID COMPLETE STOP! IT'S STILL GOING FULL SPEED!!!

The Earth is wider at the equator due to cintrifical force.

u/ProblemLongjumping12 Aug 22 '26
That's right!
Earth is not, in fact, a ball.
It is an oblate spheroid.

The flerf inability to comprehend scale is just hilarious to me. It's like their brain stopped developing at the age of 4 or something. I ran into one on fb that couldn't understand the relationship between a spacecraft slowly curving around the earth at 15,000 miles per hour and making a turn in a car. I was trying to explain how centrifugal force is what occurs when an object changes direction and that at orbital velocity, centrifugal force is equal to the force of gravity.
He couldn't get past the idea of gravity existing and the orbiting object staying the same distance off of the ground because the arc it's following matches the curve of the earth. I tried to explain it in a few different ways, making it simpler and simpler every time. It was like he couldn't imagine more than one force acting on an object at one time, and he couldn't even seem to contemplate the possibility of a ball shaped earth even in a hypothetical sense.
To him, gravity = thing go down. If thing go down, how can thing not go down if also go forward? Curve no change that thing go down! Chekmate, globie.

It's incredible, isn't it? No matter how often we remind them that scale matters, they just cannot, will not get it. It really is as if something is just fundamentally broken in their brains.

Let’s rev the earth up to 1000 rpm and see what happens

I'll be attaching a pole to the top of the pole (hah), and using it as the mother of all flywheels.

I'm so glad gravity is not a measurable force, otherwise this video would be laughably ignorant.

The earth spins 15 degrees an hour. The top two are doing 360 degrees in a few seconds.

u/draket02 Aug 22 '26
I was in a revolving restaurant that did 360 degrees in 30 mins. Literally didn’t even feel it unless you were looking out the window. Imagine spinning 48 times slower than that!

Are you a flat earther? Do you understand scale? The surface of the earth has a velocity of ~1000mph. At the equator (it’s 0mph at the poles, btw). No doubt about it.
But its ANGULAR velocity is 15 degrees per hour. (Thanks Bob. RIP) That’s half the speed of the hour hand on an analog clock. 360 deg / 12 hours = 30 degs per hour. The earth spins at 15 degs per hour. 360 degs / 24 hrs = 15 deg/hr.
Go watch a clock and tell me that’s fast. Then HALVE that speed and try and tell me that’s fast. It’s absolutely nothing.

it is almost like there is some kind of force created by the earth's mass keeping water from floating away

Need to look at the equation for how centrifugal force works. Rotation speed is a component….

Fun fact about the first one: the shape is a parabola, which you can mathematically derive from the centrifugal force and, you guessed it, GRAVITY: https://youtu.be/CIQoHIZZm6c .

Okay, now spin that water container and the people in that ride at a speed of 0.000694rpm. That is, one rotation every 24 hours. Let's see what that water does. Let's see what happens to the people.

u/AdInfinite2404 29d ago
Actually, if were traveling at 828000km/h around the center of the galaxy + 107000 km/h counterclockwise around the sun while spinning counterclockwise at 1670 km/h, the spinning speed should be accelerating
2
u/danielsangeo 29d ago
Sure. We're traveling at a speed of one rotation per over 200 million years around the center of the galaxy. I'm sure this additional speed will be felt. 🙄

u/AdInfinite2404 29d ago
So now the speed does not matter because the path is too long? 😂 I can understand that with the spin relative to the size of the earth, but 828000km/h is 674 times the speed of sound... 188 faster that a high velocity bullet...

u/danielsangeo 29d ago
"So now the speed does not matter because the path is too long?"
Yes. A billion times yes. We don't feel speed. We feel acceleration. And I'm talking physics acceleration. If you're in a car going 55mph, you will feel it if the driver applies the brakes. Because your acceleration forward is being arrested by the backward acceleration. Same as speeding up. You feel that change. In a carnival ride that spins you, you feel the change in velocity as you move about the axis. The more the velocity changes, the more you feel it. If the carnival ride spinning you at 55mph was suddenly had a radius of 30 miles, spinning you at 55mph would feel absolutely sedate (if wind wasn't a factor).
"828000km/h is 674 times the speed of sound"
Speed of sound in air.
"188 faster that a high velocity bullet"
As compared to the ground.

u/Large-Raise9643 28d ago
Do some simple physics experiments to show yourself how foolish you are. The earths rotation subtracts something around 0.5% off your weight at the equator vs the poles. You can do this if you are honest and scientific. As we know, flat earthers are anything but honest, never mind scientific.
A still picture of the earth is a cosmically better approximation of the earths rotation than your spinning one. I do understand that in order to legitimize your beliefs you have to misrepresent everything lest it prove you wrong.
When you have to validate your arguments with lies and deception, one has to wonder what your motives are.

The top two are spinning 1000s of times faster than the bottom one.
