Dixon, What is that science Law of when you spin something and something breaks off of that thing you spin, the detached thing spins in the same direction.

You kow like when you put a kid on a merry go round and spin it so fast the kid goes flying of he keeps the smae spin as the merry go round was spinning, unitl he hits a tree or car or something.

I can't remeber the name of that law.

 

[Dixon Carter Lee]

Entropy? Inertia? The Third Law of Calliope Torture? I don't know.

 

[Mustang Sally]

Sounds like the Gravitron, the one ride at the fair with the ability to make me feel sick.

 

[Angelique]

Todd, if you're trying to figure out how to play Spin the Bottle, you're going about it the wrong way, darlin'.

 

[Vlad]

Centrifugal force

I think you're describing the law of centrifugal force, Todd--

Vlad

 

[Purple Haze]

What causes the kid to fly off is called centrifugal force.

As far as the kid spinning, I've never seen it,

but then I don't get out much.

 

[Todd]

Does the 'Conservation of Angular momentum Law' sound right?

[Purple Haze]

It sounds like a movement, do you need to visit the lavatory?

centripigal force with inertia

I can't spell...that is it though, I just asked my professor after he caught me on my laptop at school on lit...hehe...

ARe you at school LAVA? cool

Is what I said a law or rule of physics? Can you ask perrty please?

 

[Todd]

I think it dictates that in a frictionless environment when an object breaks off of anothe spinning object it will spin in the same direction.

Does this sound Right Dixon?

 

[Dixon Carter Lee]

No it doesn't. Then again, I'm still resisting the whole notion of desribing quarks in "flavors".

 

[Whispersecret]

No offense to Dix, but what makes you think he knows this shit, Todd? It sounds like you already have your answer. I'm no physics major, but I think if a kid was on a really fast merry-go-round and it suddenly stopped, he'd go flying off it in a straight line.

 

[Todd]

I thought quarks tasted like chicken.

but on the original though i was trying to form, is there a law or rule similar to what I am describing?

 

[Dixon Carter Lee]

Todd is the master of the closed system models -- and I'm sure he's describing a force that is best observed in a frictionless environment (in which case the kid WOULD continue to spin).

Thats with the object stoppign that he would go in a straight line, what i am thinking if the merry go round continues to spin and the kids flies off.

there is a difference. The one where the merry go round stops the kid godes ina straight line but i have seen the merry og round continue spinning and the kids maintains the spin until he hits the ground, a tree or a slide as i saw at the time. This is the one I am trying to figure out

I am understanding of this question! It is always just doing the spinning and the spinning over and the over again and the again. I have been myself the Gnufi on this spinning merry go round! You are making the referencing comparing this spinning merry going round to the way life is always being. Yahs?

I am being the very afraid too because it is this being the type of the law you are telling the Gnufi about in the other thread where you will have to make us stop breathing if we are breaking this law?

 

[OUTSIDER]

Tangent's (sp)......?

Is space frictionless?

No need to be afraid with this law no one will stop you from breathing if you break it.

So is space frictionless, or would it have been at the point when all matter was the size of a pinpoint?

Oh boy, Physics! I may be boring as hell but I know my physics.

First off, lose the concept of centrifugal force unless you want the physics geeks to laugh at you. There really is no such thing. What does exist is inertia, the tendency of any body in motion to continue with that motion until acted upon by another force. This is the phenomenon that causes a kid on a merry-go-round to project off in a straight line tangential to the curve of the merry-go-round when they let go. Centripetal Force is the force equal to the inertia that actually pulls the kid toward the center of the merry-go-round. When your centripetal force equals inertia, you stay put at a fixed radius from the center.

Now, what Todd is talking about is conservation of momentum. Momentum is the product of mass and velocity for any moving object. Conservation of Momentum is the law that kicks in for Elastic Collisions (Billiards Players have an intuitive sense of this). Basically, in an elastic collision, the product of mass and velocity (without getting insane, recognize that product is on a vector sense of dot products taking into account direction) for all objects in a system have to be equivalent before and afterward. Of course, this is entirely theoretical since the Second Law of Thermodynamics forces some energy to be lost to friction/entropy so Conservation of Momentum is a theoretical law.

Conservation of Angular Momentum is just a subset of the Law of Conservation of Momentum. Angular Momentum is just regular ol' momentum created by an object whose velocity consists of spinning about a centerpoint. Not just any centerpoint, but the centerpoint of the object itself. Like a basketball spinning on Meadowlark Lemon's finger. The kid on the merry-go-round isn't spinning in this sense since he is actually just rotating about the center of the ride. From a physics standpoint, the kid is nothing more than a fixed amount of mass going for a ride at a distance from the center of the merry-go-round to his center of gravity. A good example of this in action is a spinning figure skater as they bring their body in tight, they spin faster, when they spread their arms out, they slow down.

I know this is more than anyone cares to know but there were about four questions asked and half again as many suggestions.

And Fuhrermore

Space ain't frictionless. Nothing is. If you have any matter at all, friction (or some other form of energy waste) will occur in any process. Space is close to being a vacuum but not quite. If you check on some of the NASA stuff, you will find that the energy consumed to move ships around in space, once you are free of Earth's atmosphere is incredibly small, but not nonexistent. Spaceships don't coast.

Hence, the notion of what happens in a black hole or other highly dense site is that of course friction happens. Gravity pulls any object (including light) intensely towards the center of mass of the black hole eventually bringing it to a complete cessation of motion. At least, theoretically since we can only indirectly observe black holes' effects on other stuff (remember, light doesn't even escape).

As a side note, physics geeks like to laugh at the sound effects in sci-fi movies when stuff happens in space. Sound is propagated from waves bouncing off of environmental molecules and other objects. Like the old Alien promo, "In Space, No One Can Hear You Scream"
