And equations set up to fit a globe model.

So why do things fall in a near vacuum?

Of course the equations are going to fucking work, because they've been designed to fit a globe!

Buoyancy.

So the same object should fall at the same rate in a vacuum, right?

@🎃Oakheart🎃 still thete?

There*

Yes

@Amthyric ive discussed this with you already

stop asking the same thing over and over

claiming no one has answered you

Make a 100 meter tall portable vacuum chamber and test it in multiple places around the world

Then we will consider the info

How satellites go into orbit

this is how we were taught satellites work in one of my first physics courses

basically imagine shooting a canonball farther and farther until at some point it doesn't hit land but basically keeps missing Earth

so it's basically in constant freefall

if that were true, shouldn't its velocity be constantly increasing?

esp with almost no friction since it's outside of the atmosphere

just occurred to me the other day....

No because the center of gravity is changing.

It's velocity DOES constantly increase. But it's relative speed remains the same because it's constantly changing velocity is always at right angles to the center of mass it's orbiting.

It’s velocity does not constantly increase, I’m confused on what you’re trying to say, drewski

An orbiting object has a constantly changing velocity.

Because it's constantly changing directions

partially correct
the (angular) speed stays the same, but the direction changes

velocity is a vector, speed is a scalar

speed stays the same

velocity changes

Yes but velocity doesn’t increase, it just changes

V is speed in a direction. V can change without speed changing.

thats what i said

partially correct
the (angular) velocity stays the same, but the direction changes
To: partially correct
the (angular) speed stays the same, but the direction changes

@marten.aap2.0 is what you originally said

Ok but I was talking to drewski

I might have worded my original statement poorly. The velocity is constantly *changing* not constantly increasing. It can continue to accelerate while maintaining the same speed .

you cant correct someone then change what you said after being corrected

Sorry about that

But I wasn’t wrong, Chad?

marten

I’m so confused
