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

@marten.aap2.0 is what you originally said

2019-12-21 16:24:07 UTC  

Ok but I was talking to drewski

2019-12-21 16:24:10 UTC  

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 .

2019-12-21 16:24:11 UTC  

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

2019-12-21 16:24:15 UTC  

Sorry about that

2019-12-21 16:24:38 UTC  

But I wasn’t wrong, Chad?

2019-12-21 16:25:04 UTC  

marten

2019-12-21 16:25:12 UTC  

I’m so confused

2019-12-21 16:25:18 UTC  

Oh okay

2019-12-21 16:25:24 UTC  

Now I understand, the gear dude

2019-12-21 16:25:38 UTC  

Sorry, I’m slow sometimes

2019-12-21 16:25:54 UTC  

marten tried to correct someone but made a mistake, then went and changed wht he said

2019-12-21 16:26:21 UTC  

I'm still not sure why the magnitude of the velocity would not constantly increase. if i use the cannonball thought experiment.

2019-12-21 16:26:47 UTC  

mistakes are no problem but when changing what yo said after being replied to is no ok

2019-12-21 16:26:59 UTC  

assume no atmosphere, the cannonballs velocity (magnitude) would constantly increase until it hits the ground

2019-12-21 16:27:47 UTC  

need to think about it more

2019-12-21 16:27:50 UTC  

But where is the ground?

2019-12-21 16:27:58 UTC  

it essentially keeps missing it

2019-12-21 16:28:02 UTC  

That is the caveat

2019-12-21 16:28:07 UTC  

but it's velocity is still increasing

2019-12-21 16:28:10 UTC  

so it should not stop

2019-12-21 16:28:13 UTC  

No

2019-12-21 16:28:14 UTC  

there is nothing to stop it

2019-12-21 16:28:27 UTC  

imagine the boundary condition

2019-12-21 16:28:34 UTC  

where you almost get all the way around

2019-12-21 16:28:39 UTC  

Because the acceleration never adds tangentially

2019-12-21 16:28:46 UTC  

it's velocity is constantly increasing

2019-12-21 16:28:55 UTC  

It adds perpendicular ly

2019-12-21 16:29:18 UTC  

but when does it change?

2019-12-21 16:29:26 UTC  

again imagine the limit

2019-12-21 16:29:32 UTC  

For velocity to increase, it would need to add tangentially

2019-12-21 16:29:45 UTC  

It only adds perpendicularily

2019-12-21 16:29:50 UTC  

Since it is a loop

2019-12-21 16:30:07 UTC  

but it's in constant freefall. that's why astronots supposedly float

2019-12-21 16:30:25 UTC  

The acceleration downwards at one point is equal and opposite to that later

2019-12-21 16:30:31 UTC  

doesn't matter. it's in freefall

2019-12-21 16:30:34 UTC  

Net change cancels

2019-12-21 16:31:00 UTC  

hmm

2019-12-21 16:31:04 UTC  

need to think about it

2019-12-21 16:31:24 UTC  

Wait do you get it now?
