Well ???

Head-scratching stuff! It's all down to inertia and momentum.

"This day-night spin has carried you around under the sun and stars every day of your life. And yet you don’t feel Earth spinning. Why not? It’s because you and everything else – including Earth’s oceans and atmosphere – are spinning along with the Earth at the same constant speed.

If Earth’s spin was suddenly to speed up or slow down, you would definitely feel it. Because it would be a feeling similar to riding along in a fast car, and having someone either speed up or slam on the brakes!"

Then comes the problem of, how do you overcome inertia to produce momentum? I imagine an object such as a car will travel the same as us, with the spin of the earth. To make it move requires momentum.

The issue is the earth is flat not round

I guess that is one of the mysteries we will find the truth about.

What happens when you spin a bucket of water in circles, then stop suddenly?
