So I'm down in West Vancouver, British Columbia, which is where I grew up.

And at the local beach there is this 2.5 ton granite sphere that was made to have a tolerance of to hundreds of a millimetre.

程度の副詞

This is amazing granite sphere, and it's floated on a thin layer of water, and it just presents an amazing opportunity to study inertia.

And that's why I'm down here to have a chat with the with some of the people going by about why the globe spins and in fact, why the Earth spins.

I think the gravity for keep us down on the ground, right?

How does that cause the earth to spin again?

It's gravity and he guesses, looking gravity.

So why is that some sort of force that's you think there's a force down there pushing it?

Yeah, I'm gonna go because the up thrust from the water is probably angled in such a way that it's because it's a spherical shape.

What is a centrifugal force that keeps it?

Isn't Air Force that keeps going in their force?

Working around within, within, within the S cores.

They're not something that drives and dictates, said centrifugal force.

Every action equal and opposite reaction force in inertia maintains this.

But inertia, which is great idea is not a force.

It's just the tendency of all objects with mass to maintain their state emotion.

Okay, so if they're stationary, they want to stay stationary.

Moving said under your authorized objects wanted, want to keep you basically whatever motion they have, they like to continue in that state.

Yes, the Earth does that without any forces.
