What relationship exists between motion and the Universal Law of Gravity?
:gocho:

I have some crap narrated by Morgan Freeman on my DVR that I need to watch first. I'll get back to you.
I'll go ahead and throw out my guess though.
Q: What relationship exists between motion and the Universal Law of Gravity?

Gravity has nothing to do with it. Because it's not the size of the boat, it's the motion of the ocean. Hope this helps.

Centrifugal Force :dunno:

what goes up must come down

Depends, what system are you working in?
Under Newton's Law, the simplest case, distance and mass are relevant to gravitation which exerts a force instantaneously at a distance. That is, gravity moves with infinite speed.
Under general relativity the motion of massive body creates a distortion in spacetime that propagates outward from the moving body at the speed of light. It's not quite that easy but that's the general idea.
From there it gets complicated.

conic sections

equal area equal time

Seems to me that, particles are in constant motion, right? Wouldn't gravity affect the particles no matter how small?
-
you are correct saul. gravity affects eveything (but is the weakest by far all of the forces)
-
What effects would the lack of gravity or micro-gravity have on motion? I think of how water reacts in space. Just floats there like a glob of particles, doing whatever it feels like. Do the particles just move around freely, or do they have to have some sort of opposing force to move?
If there was no gravity, would it just simply move forever?
-
the simple (classical) answer:
if the particles were point particles and neutral and at rest and there was no gravity they would remain motionless.
if they were not point particles (but still neutral) they would being to accelerate due to van der waals or higher order electromagnetic forces.
if gravity was there eventually the particles would attract each other (some particles would fly away but most would begin to orbit and form clusters)

do point particles have zero mass?
-
no, but then again do point particles even exist?
tough question to answer

This thread did a quick 180 from the first few replies
-
Does absolute zero gravity exist anywhere in the universe?
-
no (at least in the known visible universe)

this thread sux

If there was a tunnel from one side of the Earth to the other, what would happen when passing through the center? Obviously if you take heat out of the equation.

You would be squashed

Nothing really. Unless you filled that hole with a huge water slide with a pool at both ends. Then, it may be pretty awesome.
-
I'm going with you'll oscillate about the center point of the tunnel going from end to end eternally if we're neglecting air resistance, and other frictional based factors.

Just to be clear, are you suggesting that a tunnel from one side of the earth to the other side, via directly through the earth's core, is impossible to use?

No, I would use it all the time.....for squashing my enemies

It's not about a frictionless environment. It's about gravity. I want to know from the smart people if sd is correct or if nothing would happen.

In that case, Linux is right.

SQUASHED!

I don't trust him. I'm starting to think squashed.

That is just large font and bold text messing with your head. Stay strong.

Why is everyone talking about building tunnels through the Earth's core, anyway?

How do we know Event Horizons really exist? :dunno:

How deep of a hole do we need before squashing starts. I have a shovel and some assholes that would keep me busy for quite a while.

It is a matter of a frictionless environment. If you include the friction and wind resistance however minimal it might be compared to that of the earths gravitational pull, then eventually you will stop oscillating about the center of the earth and will come to rest at the center. Also if we're going to take into account the smaller forces, then we should include that the earth is not a perfect sphere. Therefore, there will be pull from odd angles and not just into and out of the tunnel we create. Eventually, you may crash into the side of the tunnel unless it is a rather large tunnel.

However, i do enjoy the squashed theory.

Tarriffs and import quotas create deadweight losses which eff with efficiency.

No the hell it's not. Quit being a prick. There's a ladder in the tunnel.
-
And I never said it was a hole. You jump into holes. You don't jump into tunnels. You people need to see yourselves to the medium/low thread.

By your definition of a tunnel with a ladder would be more properly defined as a Chute, maybe even a shaft. But not just a tunnel. Perhaps you're the one who should be sent to the dumbass thread.

to briefly get back to the water in space concept - it doesn't just "go where it wants" because surface tension still exists in microgravity so the mass of water will eventually ball up (lowest SAV ratio) and then travel in a straight line in the direction of the last force that was exerted upon it.

Then it's squashing time

It would be a tunnel when you're in the middle of the earth with no definable "up" or "down".
You guys are killing me.

By definition, Chutes and Ladders are two completely diff things. One helps you win, the other is a KITN. You never encounter a chute with a ladder. Pfft.
