gravity

Was reading about the chicken warerer,and thought about another question that I have.How does gravity work? Of course I know it pulls towards the center of the earth,but it pulls everything ,not just metal like a magnet.We are spining around at something like one thousand miles an hour,yet we don,t go flying off into space,so how does science explain it.(guess I missed that day in science class) Yes Iknow It,s magic....And it,s done by our creator,How about a good simple answer if there is one.

Ask some of out Australian friends. They walk around upside down all of the time. I wonder how they keep water in their wells. I also guess that instead of picking things up they have to push them down!

Every little pice of matter pulls toward every other piece of matter. Since the earth is many pieces, it pulls harder.

Certainly makes you tired at the end of the day.There has been a drought for 10 years so the wells are empty,all the water seems to be dropping off which may explain why it was found on Mars.

Put 2 fruit loops in a bowl of milk and place them about 1/4 inch apart. They will slowly atract to each other. They actually get faster the closer they are to each other. Once they touch each other different forces come into play.

The reason the Law of Gravity is called a "law" (as opposed to a "theory") is that it can only be observed, not proven. Now there are plenty of theories around (such as those developed by Einstein) that seek to explain the relationship between the various forces of nature, but they don't really explain "why" gravity occurs. Gravity is pretty much a given.

Now Newton's Law of Gravity simply says that matter is attracted to other matter, and the force of the attraction becomes stronger the closer two objects are or the more massive the objects are. (Actually it's stated in mathematical terms, but that's basically what it says.)

You know that is a good question. But it is like you said, you know. I would guess that it is like that and if you fight it, well I dont know. One thing I do know that if you look at it in the way that most people do it, well you know. As I said that is a very very good question that is you know off the charts. If you can ask another question that maybe you can answer after, you know. Have to take a break and you know think about, you know.

Gravity is a distortion of space time.

Wouldn't it be safer to use 2 Cheerios, rather than Fruit Loops ? LOL

That"s surface tension/capillary action and very very little gravity.

The best I can come up with is things like gravity & light can be described, but not defined. Like, the effects of gravity are known, so we can land on the moon. But how you define exactly what gravity is, is a different ball game.
They're still working on a Unified Field Theory aren't they? I'm subject to correction here, bigtime. Mark SW Wis.

Listen up, buster! Gravity is not just a good idea. It's the law! ;8^)

If it's any comfort, you're not alone.

They've done a lot with physics since Newton. And a lot of it in this century. (I was fortunate enough to sit in on a lecture by a fellow who worked with Rutherford in the old Cavendish labs in England, back in the 1920s when they were trying to prove the existence of the neutron which, at the time, was still just a theoryitcal particle.)

So we've come a long way in a short time. We can build machines that can split atoms. We've learned enough that the astrophysicists and cosmologists are trying to figure out where the dark matter and the dark energy are, we've identified several layers of ever-smaller sub-atomic particles and the strong and weak nuclear forces that make them behave as they do. But, despite a lot of work on the subject, there has been almost no progress on the very basic nature of gravity, something that was identified and quantified centuries ago. It's a force. But is it a wave? If so, low or high frequency? Why can't we detect it . . . The current direction is still part of physicists' quest to to have a unified theory of electromagnetism (think of a generator --see, we made this about tractors, didn't we!) and the strong and weak nuclear forces. Gravity is the one confounding their efforts.

Here on earth, try to think of it in the sme way as the force of air pressure that we don't sense. There's something like 15 pounds of air over every square inch of your head, but you don't feel it pushing down on you. At the equator, yes, you're spinning around through space at something like 1,000 mph, but that's on a radius of something like 3500-4000 miles. But it's the gravitational attraction that keeps your feet on the ground.

Just to tie those together, I used to wonder (a question not unlike yours) why, if the earth was spinning at 1000 mph, we didn't have 1000 mph winds on the surface. That has to do with the fact that that 15 pounds of air also has a mass that is attracted by gravity, so that it can be relatively stable. Air is, of course fluid, so it responds more readily to other forces and is subject to more variance. We call the variances weather. thankfully, we are made of sturdier stuff, so that a low pressure doesn't set our gall bladder spinning one direction while our liver spins the other.

The force of gravity can be calculated as a function of mass and distance. Basically it is the product of the two masses, multiplied again by a derived figure called the gravitational constant, all divived by the square of the distance between the centers of gravity of the objects, meaning that gravity weakens more quickly with distance than it does with the size of the objects.

As a result, while the mass of your body might not change (that is, the amount of matter that makes it up), you will weigh less atop Mount Everst than you will on the beach at Waikiki, only because you are further from the center of the earth. Your feet will be in contact with the same planet, but you are further from it's center of gravity. Go figger.

Gravity is the attraction between rubber and steel that always attracts the small part you drop to the most remote area between the tread bars... Gene

I have to think it's one of God's miracles mankind will never explain. It takes everything working together to make life possible, but some say just a big bang organized this. And- it's interesting to me to think, if you could drill a large hole through to China, that if you fell in, near the center of the earth you'd come to a stop with nothing but space still ahead. Of course it would be beastly hot, like molten lava temp.

Joe Newman explained gravity and a unified field theory in his book published in 1984. You can order it from his site.

Duh, gravity--kinda like a magnet.--The world is a positive pole.And you the negative. it works this way the more you eat, the more magnitizim you have to hold to the earths surface without falling off. you can prove this by taking two men of different weights ,like a 300 pounder' and a 120 pounder and put them in a wind tunnel and keep increasing the speed until they get blown away so the bigger magnet you are the better.If gravity alone was keeping us all stuck to the earth we would all weigh the same,because it is an equal force.
[ Not being smart, just having fun]

Oh, let's face facts: we don't have the faintest--not the faintest--idea. And all this ritualized mumbo-jumbo about "dark matter", "dark energy", "strong forces", "weak forces", ad nauseum are just efforts to sound all-knowing by people who are deathly afraid of saying "Gee..I dunno..."
We'll eventually figure it out, if we don't blow ourselves up first; I just get tired of the mindset that thinks anything is better than saying "We just don't know" (yet).

Didn't your mother ever tell you not to play with your food? LOL

A LAW ! Is there any chance it may be repealed? Congress needs something to do.

There is no gravity, the Earth sucks.

"GRAVITY IS THE HUNTER" according to my wife as she climbs on her exercycle....
For me its what pays the bills around here...
OCG

The answer may be coming soon. The worlds largest particle accellerator (17 miles long)will fire up in Switzerland this week with the goal of finding math predicted sub particles and ? See this week Ecomomist magazine.

Ken in Texas - No such thing as gravity. It's all atmospheric pressure. bob f.

If you are underneath a vehicle and take a part loose, and aren't ready to catch it when the last bolt comes out, it will hit you in the face and hurt real bad.

That is why I have two front teeth capped.

What a waste! Joe Newman explained it in his book back in 1984.

Gravity is one of the fundamental forces of nature, like electromagnetism and the nuclear forces that bind matter together. Basically, all matter is attracted to all other matter. The strength of the attraction is a function of the mass (in your case, the earth and your body) and distance.

For example, astronauts on the moon weigh less than they do on earth because the moon has less mass and therefore less gravitational attraction. Note the difference between weight and mass - mass is a measure of the amount of matter in an object, weight is a measure of the gravitational attraction.

We have a pretty good understanding of the effects of gravity, including the relativistic effects on time and space. However, physicists are still working on understanding how it works at the sub-atomic level. Physicists are working on what's called a "grand unification theory" that unifies the four known, forces of nature; the weak nuclear force, the strong nuclear force, electromagnetism, and gravity.

By the way, Joe Newman is basically a nut case. If you look carefully at his "energy machine", it never produces more energy than what is put into it. Notice he never shows a measure of energy in vs energy out, only "demonstrations" that really don't demonstrate anything new. There's a reason he's never been able to get a patent; it simply doesn't work.

Just like global warming, gets stronger every year.

And then, when you move the tractor out of the way to get it, it rolls into the floor drain before you can grab it. Or if you didn't think about looking under the tire, it just stays there so you can see it there after you put the new one on that you got by driving 20 miles one way.

"There's something like 15 pounds of air over every square inch of your head, but you don't feel it pushing down on you."

Are you sure that the 15 pound of pressure pushing down on my head isn't due to the 15 pounds of vacuum inside? hehe.

Gravity not getting stronger, I'm getting fatter.

The most important thing about gravity is that mankind is not capable of comprehending or bettering it because the one great God had it in His master plan for His universe and we just need to accept it!

gravity works like this it does not hurt to fall ,it's the sudden stop that gets you each time
