If by "gravity neutral" you mean "not affected by gravity" the answer is none. Gravity is an attribute of curved space-time and thus everything in space-time is affected. Even massless photons curve in the presence of massive bodies.

What you're describing is called the "Three-body problem" in Physics. Since Newton

wrote his law of gravity, the problem has been studied by every big name in Physics

and Math, including Newton himself. Now, in 2013, it's still far from being completely

understood, and there's no general solution, so you shouldn't feel so bad.

A simple pendulum is an idealized system. It's requirements like the bob should be a heavy particle, suspension string should be massless, perfectly inextensible etc. cannot be achieved perfectly. On the other hand a compound pendulum is a rigid body of any shape capable of vibrating about a horizontal axis passing through it(not through the centre of gravity), so it does not have such ideal conditions. Hence it can give more accurate result.

( I think this is the answer, may be there are other advantages also)

yes, anything with a lower atomic number would be lighter, for example, helium is lighter than air, which is why balloons float when filled with helium... the lighter substance rises above the heavier....

I have been there several times. Gravity is all screwed up. Balls roll up hill, people change heights, compasses spin out of control and you can stand perfectly comfortable feet together sideways at a 30 degree angle. At first I though it was a forced perspective optical illusion. But you can feel the force on your body and explain the compass. What sold me that there is really something here, the cat. Kitty is not up trickery. But I stood a the bottom of the hill/zone and watched the cat walk up the path, whoop kitty is completely leaned over walking normal. Okay research, the most commonly believed is that there is a huge magnetic iron outcrop just under the surface that was left over from the creation of earth. Or a iron meteorite as Einstein theorized. anyways LIGHT BENDS in the zone. And it's really not that hard to believe that in this incredible magnetic Field gravity does not go straight down. I did a test by dropping a ball. Straight down? Off the side at an angle, Yes. See with your own eyes, feel the force, Then explain.

Whatever goes up and remains within the influence of earths gravity must come down, or circle the earth as a satellite.

Gravitational forces bend the fabric of space and time. Clocks relate the local measurement, so all clocks, digital or otherwise, are affected.

it will float. The water bonds to itself and if one droplet runs into another, there is a good chance that they will combine and move together

I just learned about this in chem11. I'll give the definition off my sheet.

Specific gravity is a dimensionless unit defined as the ratio of density of a material to the density of water at a given temperature (usually at 4oC).

Note that this expression is obsolete today; use the density.

Volume is the amount of space taken up by a substance like a container. It always does not to be an container it also can be a car or a bag .e.c.t.

The amount of 3-dimensional space occupied by an object.

One could be falling. Another could be not exploring space like we would like to.

That's all I can think of, right now.

Here's more: If there were no gravity anything not fastened down on Earth would fly off into space. Similarly your meal would fly from your plate (screwed down) to the ceiling. Waterfalls, even if they could exist, would rise, not fall. So they would have to be called "water-risers". If you jumped that would be the end of you. No gravity would mean no weight so you could carry more in your rucksack - but don't put it on the ground or you'll lose it.

Advantages of gravity: Everything has a weight due to the Earth's pull. That keeps everything down - your apples on the trees, your bike on its tyres, waterfalls would fall, and so would rain. Golfers wouldn't lose so many balls. And I'm sure that you can think of many more now.

No, but certain properties of gravity can simulated, using a magnet.

When you hit the white ball, the kinetic energy created from moving the cue, is transferred to the white ball on contact. This causes the ball to move, and depending on how fast you move the cue, will cause the white ball to move at different velocities.

Yes; if density is lower with same weight it will have bigger volume, hence more air resistance when catapulted and hence less distance traveled

If you are referring to the fundamental forces of nature; there are four, being:

-Electromagnetism; this is the force responsible for all things involving magnets and electricity.

-Gravity; this is the force that causes objects with mass (more correctly energy) to attract each other. It causes things to fall down and is probably the force most people are most familiar with.

The last two forces are not generally known because their influences usually are only felt in the world of small things such as atoms, and their influences are only rarely seen in the every day world.

-Weak nuclear force; this force governs certain interactions of sub-atomic particles and in particular it is responsible for radioactive decay.

-Strong nuclear force; this force works on only a few types of particles; particles which have a color charge. It is, for example, responsible for binding the protons and neutrons together inside an atomic nucleus. Without this force the nucleus would be pushed apart because the protons repel each other electromagnetically.

-- Borrow a bathroom scale.

-- Place scale on a hard, flat, level surface.

-- Place the unknown object on the scale.

-- Read scale display.

-- Record in notebook.

-- Return to lab with notebook.

-- The quantity noted represents the magnitude of the mutual gravitational force between

the earth and the object under study.

-- Send scale to the Smithsonian.

-- Eat the object under study.

-- Add graphs, charts, formulas, and descriptions of method of procedure.

-- Publish.

Mass, not density, and the closeness of objects, affects an object's gravitational pull. Density is not dependent on an object's size, but mass is. The more massive an object, and/or the closer an object is to another, the greater its gravitational pull.

On Earth, 1 kilogram of mass weighs 9.807 newtons (2.205 pounds).

By comparison, on the surface of Venus, the same 1 kilogram of mass

weighs 8.858 newtons (1.991 pounds).

A hefty adult who weighs 200 pounds on earth would weigh 180.65 pounds

on Venus.

Assuming no air resistance, the speed of a ball increases by the same amount it decreased when going up due to gravity. This means the ball gains the same speed returning to its original point as it lost when it was thrown upwards.

Well, if you increase the pressure of the atmosphere, isothermally, around water high enough, then you will overcome the 'vapour pressure' of the water, or the pressure of the water's surface back on the atmosphere to put is very, very simply. SOOOO, if you increase gravity, then you increase atmospheric pressure, which will condense any water vapour in the air. You can decrease gravity to see that the vapour pressure of the newly condensed liquid water will overcome the atmospheric pressure and vaporize. Keep in mind this works in standard conditions, not at extreme temperatures and pressures.
