Gravity

Gravity walls are supported by the earth itself in the downward direction. This generally applies to retaining walls. A Cantilever wall is not supported directly by the earth, but it is connected to another structure that is anchored. The cantilever wall, or any other structure containing the term cantilever, suggest that it "hangs out" of another anchoring structure without direct support from underneath.

Gravity is mediated (i.e. comes from) a particle known as a graviton. Now, the force of gravity on earth neither increases or decreases, it does however vary depending upon your geographic position. Despite this, the values of gravity all center around the average of 9.81 meters per second per second (remember that gravity is a downward force causing an acceleration).

well...there are about 3 projects that i know of that can demonstrate the center of gravity but i only know how to do one of them. okay!! now before you start the project this is what you're going to need in order to accomoplish it:

2 tooth picks. it doesnt matter what type but you might want to use the pointy ones are better (you might to bring a few extra because there is a chance one of them may break

2 metal forks they have to be the same size

now that you have the materials lets get started!!->

Step 1. take both of the forks and take the prongs and put them together so that theyre locked in place.

Step 2. take one of the tooth picks and stick in the space made between the two forks. it has to be in the second space for both of the forks. make sure that the toothpick is locked in there. now it doesnt have to be totally perfect just make sure its in there well enough.

Step 3. get the second toothpick and have you or some one else hold it in your/there hand very steady. at least half of the toothpick must be visible while you are holding it in your fist or straight up in the air.

Step 4. when you are holding on to the toothpick in the froks make sure that is what you are holding on to-the toothpick. if you have done step 2 right you should be able to hold the toothpick without it falling out.

Step 5. place the tip of the toothpick that is between the twon forks on top of the other toothpick that you or someone else is holding. if you have done this right than the toohpick holding the forks should be able to stand on the toothpick being held alone.If you have completed the following steps with the correct results[:^!!BRAVO!!^:] GREAT JOB...if not than go to youtube; there is a video of someone performing this exeripment

The center of gravity is the theoretical point where all the body weight is concentrated or the theoretical point about which the body weight is evenly distributed. If a body is of uniform density and has a symmetrical shape the center of gravity is in the geometric center. If the object is not symmetrical and does not have uniform density, it is more difficult to describe the location of its center of gravity.

Gravity can be measured many ways. You can drop an object and observe how it falls and determine the objects acceleration. With that in hand you can then calculate the force required, and measure gravity that way.

You can use a scale, and determine the force acting upon the object placed on it to compress the springs a certain distance, or deflect it a certain distance (depending on the scale's design).

A pendulum can be used to measure gravity. The period of a pendulum is directly influenced by the magnitude of the accelerating force (gravity) you can measure altitude with a sensitive pendulum.

As gravity is a force, any method you would use to determine the force of one object exerting upon another would work to measure gravity.

All substances have volume, but gravity is not a substance; gravity is a force and has no volume.

No, gravity is a fundamental force in nature. It is responsible for the attraction between objects with mass. Pseudo forces, on the other hand, are apparent forces that arise in non-inertial reference frames.

It's a strange and fascinating fact that in asking your question, you've used EXACTLY the same

wording as another person, who posted EXACTLY the same question here on WikiAnswers, did ...

and both of your questions apparently refer to the same drawing or picture or previous description

that neither of you has included with your question. It's almost as if the two of you are either

identical twins separated at birth, or else both trying to get WikiAnswers volunteers to do your

homework or take your test for you. Fascinating!

Anyhow, since you mention "the falling body", we think you're actually asking whether heavier

objects fall with the same or different accelerations compared to lighter ones.

The answer is that as long as you test all of them on the same planet, and they don't run into

too much air, the lightest feather and the heaviest battleship, and everything in between, all

fall with the same exact acceleration.

Zero gravity does not occur at a specific distance from the Earth's surface. The sensation of weightlessness experienced by objects or astronauts in space is due to being in free fall towards Earth while moving forward with enough velocity to stay in orbit. This can happen at various distances from the Earth's surface, depending on the object's speed and trajectory.

The gravity on Saturn is approximately 1.07 times the gravity on Earth, or about 10.4 m/s². This means that a person or object on Saturn would weigh slightly more than on Earth due to the stronger gravitational pull.

The gravitational attraction between two masses depends on the product of their individual masses (direct proportion), and also on the distance between their centers (inverse square proportion).

Yes, the surface of a hill can affect how fast a ball will roll down it. A smoother surface will have less friction, allowing the ball to roll faster, while a rougher surface will create more friction and slow the ball down. Additionally, the incline of the hill will also impact the speed of the ball as steeper hills will cause the ball to accelerate more quickly.

At the center of earth or any other heavenly body.

Helium and hydrogen gases are light enough to escape Earth's gravity, although this process occurs very slowly. On the other hand, heavier gases like oxygen and nitrogen are retained in Earth's atmosphere due to their higher mass.

Gravity determines the weight of an object. This is different from mass which stays constant regardless of gravitational pull. This explains why astronauts become "weightless" in outer space even though there mass is the same.

No. In Newtonian physics, gravity is treated as an instantaneous force, but in General Relativity, gravity propagates at the speed of light in a vacuum. There's some debate on whether it's actually been experimentally shown that the "speed of gravity" is the same as the speed of light in a vacuum or not. However, there is fairly clear experimental evidence that it does have a speed and is not instantaneous. See the Wikipedia article in "Related Links" for a much longer and more detailed discussion.

Gravity is gravity. It doesn't matter what the mass is made of, just how much mass is present. The Law of Universal Gravitation is F = G m1m2 r-2 where F is force, G is the gravitational constant, m1 and m2 are the masses of the two bodies, and r is the distance between the centers of mass of the two bodies.

Mars has about 38% of Earth's gravity, meaning that objects on Mars weigh less than they do on Earth. For example, if you weigh 100 pounds on Earth, you would weigh about 38 pounds on Mars.

A space croissant Or a change in vehicle attitude produced by using lateral thrusters to roll the vehicle like a barrel until it is in the desired position. there is really no up or down in space so you can't really say upside down but that is what you are doing.

For the density of compacted asphalt pavements: 1,75-2,4 g/cm3.

For liquid asphalt: approx. 1 g/cm3.

To not let anything bring you down.

Triton's equatorial surface gravity is 0.779 m/s2, earth's is 9.780327 m/s2

It is called a theory out of convention. Some biologists refer to it as Darwin's Law of Evolution, because it is pretty well established.

In science, a theory is any well substantiated explanation for some aspect of the world. That is why we have Newton's theory of gravity, and Einstein's even better theory of gravity (General Relativity).

Evolution is both a well established fact (it has been observed, and it explains the sequence and arrangement of the fossil record), as well as a scientific theory (descent with modification, or random mutations coupled with natural selection, or that most modern (and extinct) species share common ancestry.

Evolution is a fact, not a theory. How it proceeds are the various theories.

When people use the term 'theory of evolution' they are generally, referring to Darwins theory of how evolution progresses. Which is through natural selection. That is a theory not evolution.

0.92 (times Earth's surface gravity).

Edit :

OK this one is a bit tricky. It is usually given for Saturn's equator. It does

depend on latitude. Also the rotation speed affects the "apparent gravity" because of "centrifugal force", but this doesn't affect the underlying force of course. So you will see some variation in the figures quoted, depending on definition, etc.

I looked at a NASA pages for this and they give two different values. One is the answer above, given by a previous contributor. The other value is:

1.065 x Earth's.

Most sources seem to agree things would weigh a bit more on Saturn, but it's a bit confused.
