Do you agree with this - " If you die in the same hospital you were born in, then your average velocity will be 0"?

[Eryxx]

I agree.

I disagree.

Other.

[ShortCircuit]

Indirectly, yes. Your displacement is zero, and since average velocity is total displacement over total time, zero over anything is zero. I was actually thinking the exact same thing when I was being taught 1D Kinematics last unit.

Although, I don't actually believe it's possible to achieve "zero" displacement, because it would require your feet (or whatever is the subject of the problem) to be in the EXACT spot they were initially, down to infinitesimally small units of measurement.

Hilarious

Lmao dude 😂😂😂😂

[Anonymous]

I dunnno

[Eryxx]

Lol too predictable

[Opinion Owner]

Nooo

[Eryxx]

Yeah

[Devourtheuniverse]

it depends.

Average velocity relative to the center of Earth? Maybe. You could argue that differences are negligible.

Average velocity relative to the sun? No, not necessarily. In fact, it's much harder for this to be true. Obvious things like day of the year and time of the day have to match up. Then there's the fact that the Earth doesn't have a completely fixed orbit around the sun and that though the differences in orbit are negligible on an astronomical scale, the unaccounted for displacement would probably yield a net velocity which would be impressive for a human.

With respect to the galaxy? Not a chance unless you live for 230 million years ( to the precise value of a period around the galaxy).

And all of this is just common sense and slight arithmetic. I'm sure special relativity would make things a whole lot more difficult.

But I'm going to say no. Your net velocity won't be zero.

[Devourtheuniverse]

Oh also there is the chance that they die at the exact same place they were born, but they're not stationary or moving in the opposite direction they were moving as a baby being born (maybe they popped out). So maybe the initial and final velocity do not cancel and thus a net velocity other than zero is produced relative to the center of the earth.

I like to imagine someone jumping to save another from a projectile and somehow dying in exactly the same pose and position they were born in but with a much greater velocity.

What do you think @Eryxx?

[Devourtheuniverse]

sorry if that wasn't very clear lol.

[Eryxx]

Well in your case, if the person dies moving with a velocity, but doesn't stop moving after dying, I guess his velocity will not be averaged out to zero.

But I'm a bit confused about the latter situation, what do you want to conclude?

[Devourtheuniverse]

Oh no! I'm dumb. That doesn't change anything! Net velocity is net displacement over time, even once instantaneous velocity is accounted for. My argument doesn't hold up at all. And more rigorous mathematical arguments (I. e. integral and vector calculus) make my fallacy all the more obvious.

*mega facepalm* I should've stopped while I was ahead lol

[Eryxx]

Integrals and calculus? Damn man.. that's my favourite part along with physics.

Well considering DISPLACEMENT per unit time is velocity, it can be zero w. r. t but the chances are infinitesimally less.

[Global_Highway_Man]

Whether I'm right or wrong, I dont care. That was a bloody brilliant questions😀

[Eryxx]

Thank you.

[MrKinktastic]

Hopefully a bit of time passed which is a sort of space to be traversed so no I wouldn't say 0.

[Eryxx]

Tends to zero?

[MrKinktastic]

Nah, they did stuff they just went full circle

[Eryxx]

You're talking about speed.

[MrKinktastic]

I dont think you have a very good grasp of physics my friend :p velocity and speed both describe the rate at which an object is moving. In this case they did move, they just came back. Also they moved forward through time.

[MrKinktastic]

Also the world and even space itself is moving, there's no such thing as still in an expanding universe

[Eryxx]

Never consider speed to be velocity. Displacement is not distance man. And while solving the problems, we don't take into consideration the movement of earth in space duh.

[Devourtheuniverse]

I agree this is obviously a displacement question.

I disagree that we must necessarily assume the earth to be our reference frame.

[Eryxx]

@Devourtheuniverse taking the velocity w. r. t things around space will never make it zero. But still let's be on Earth for now.

[Devourtheuniverse]

But I want to devour the universe...

[Eryxx]

Interesting.

[up_64]

Your net forces will equal zero since tou have undone the distance.

[up_64]

But your energy will still have been spent.

[Eryxx]

I agree.

[Guanfei]

Unless you die at the exact same spot of your birth, it's wrong.

[Eryxx]

I agree.

[Muhammad1999]

nope unless you die inside your mom when you get old.

[NovissimumVirorum]

Impossible for me, the hospital I was born in is now expensive condos

[up_64]

Get of gag and start working😂

[avalonbob]

Is this one of those String Theory questions?

[Eryxx]

You may take it as you like

[avalonbob]

O. K. I've given this a lot of consideration, and I can come up with 11 Dimensions, but concede that there may be as many as 17.

[Xylem1992]

hilarious and original. hats off to you sir

I thank you.
