Gravity

Mostly because Saturn has almost 1,000 times as much mass as Mars has.

Their difference in physical size also affects the relative values of gravitational

acceleration at their respective surfaces. But that 1,000 times ratio of masses

is pretty easy to understand.

A quick way out would be to tell you that it does so because Einstein's theory of general relativity says it does and that we can check that it does and that the theory makes correct predictions, however a more deep explanation might be as follows:

It seems to be the case that the laws of physics are the same in every reference frame; this means that you can have your laboratory on the Moon, in deep space, accelerating or even rotating and all your experiments should leave you to deduce the same laws of reality. This is called coordinate invariance.

Now if you want to have this coordinate invariance, gravity MUST bend time. It is a direct consequence although a bit mathematical to show (but it can be done).

I might make it a little more clear by using special relativity instead, which basically is the consequence of coordinate invariance except that it does not allow for accelerations (therefore the general theory of relativity is the more general theory). We shall call this inertial frame invariance (an inertial frame is a frame that does not accelerate, a frame is basically a coordinate system).

Now, one law of physics is the constancy of the speed of light. According to inertial frame invariance one MUST arrive at this law always, regardless of which inertial frame you happen to be located in. But this causes problems, because this would mean that someone shooting a laser on a train must measure c (the speed of light) but someone standing still on the station must also measure c even though the train itself is moving! The only way this can be true is if the train shrinks in the direction of motion and time slows down for the person on the train. These are the time dilatation and length contraction predictions of special relativity. These effects occur because the laws of physics are the same in every inertial frame. It must be true or the speed of light would not be constant for everybody.

In the same way gravity must bend time. In fact you can even show that gravity itself is a consequence of coordinate invariance. If you want coordinate invariance you must have gravity.

The Moon's gravity causes the tides on Earth by exerting a pulling force on the oceans. This gravitational interaction also causes a small effect on Earth's rotation, slowing it down over time. Additionally, the Moon helps stabilize Earth's axial tilt, which contributes to the planet's climate and seasons.

Yes, gravity is a fundamental force that exists throughout the universe, including other galaxies. The strength of gravity depends on the mass of an object, so larger galaxies will have stronger gravitational fields.

Gravity is a force that exists, it is not like someone thought of it and then simply things started to fall down.

It is very likely mankind discovered that things fell down after being thrown up at early stages of their development.

As for any scientific theory of gravity, describing in mathematical terms what it does, this is usually credited to Isaac Newton who published his equation in 1687.

The gravity is less on the moon than on Earth because the Earth has about

80 times as much mass as the Moon has.

The diameter of the Moon also affects it. If the diameter is bigger, that puts you

farther away from the center, and the gravitational force decreases.

The laws of gravity seems to be the same everywhere in the Universe. There have been experiments using distant objects in the Universe to try and measure if it might be different far away (or back in time!), but no effect has been found to date.

In fact, the question seems to tie in with the question whether the laws of physics are the same everywhere in the Universe. This is because one can derive the equations of general relativity assuming the laws are the same everywhere for everyone. This is a bit technical, but basically if you want the laws of physics to be the same for everyone you MUST have gravity in the form Einstein proposed, there is no other way.

Of course other deviations from our laws of physics have been looked for, but again none have been found.

Yes. According to the theory of general relativity, gravity is the result of matter (and more specifically energy) bending space and time.

Concretely this means that time slows down there where gravity is stronger. This implies that time goes quicker for someone in an airplane than for someone on the ground (who is thus deeper in the gravity well of Earth), and this effect has actually been measured. The effect is very tiny because gravity isn't very strong here on Earth so we don't notice it ourselves, but using atomic clocks we can measure it, and it agrees with what Einstein predicted.

In fact the GPS satallites had to have been corrected because their clocks ticked somewhat quicker than those on Earth!

As an extreme example, at the horizon of a black hole the force of gravity is so huge that time stops completely there.

No, gravity is a universal force that acts between all objects with mass, not just on objects on the Earth's surface. The strength of gravity decreases with distance from an object, following the inverse square law. This means that gravity affects objects in space as well as on the Earth's surface.

Gravity is a fundamental force of nature that exists throughout the universe and is constantly acting upon objects with mass. It does not need to be "found" as it is always present. Scientists study, understand, and quantify gravity to explain how objects are attracted to each other and how celestial bodies interact in space.

yes gravity pulls object toward the earth

Here on Earth, the force of gravity does indeed pull objects down toward the Earth. But bear in mind that gravity is a universal force. On the planet Mars, for example, gravity pulls objects toward Mars. All objects in the universe have their own gravitational force, the strength of which depends upon how massive the object is. The sun is much heavier than the Earth, and the gravitational attraction of the sun is enormously greater than that of the Earth.

Gravity is the force responsible for bringing together gas, dust, and stars within galaxies. It acts to pull these materials closer together, leading to the formation of structures like galaxy clusters and superclusters. Gravity also influences the movements of objects within galaxies, such as stars orbiting around a galactic center.

I'm not familiar with a specific "gravity perseus attack." It is possible that you may be referring to an attack in a video game or other fictional media. Could you provide more context or clarify your question further?

Zero gravity, also known as microgravity, occurs when an object is in freefall and experiences an apparent weightlessness. This is commonly observed in space environments such as the International Space Station. While true zero gravity does not exist in a gravitational field, there are environments in which the effects of gravity are minimal enough to create the sensation of weightlessness.

The substance on Earth that experiences the greatest gravitational pull from the moon is the oceans. The moon's gravitational pull causes the tides as it attracts the water on Earth's surface towards it.

Good question. currently we don't, but i would think the easiest way would be to have the space station or ship rotate at a specific speed, and then have the rooms angled so you are kind of standing on the side of the ship and the centrifugal force would push you down like gravity, and you could have it spin just right so the force is the same as gravity on earth

The acceleration of gravity on the surface of Pluto is 0.583 m/s2 .

That's 5.94 percent of its value on Earth.

If you weigh 200 pounds on Earth, you would weigh 11pounds 14.2ounces on Pluto.

The gravitational pull from Jupiter to the sun is stronger than the gravitational pull from Saturn to the sun. This is because Jupiter is more massive than Saturn, so it exerts a greater gravitational force over larger distances.

Gravity discs are used to create a gravitational field that can simulate the effects of gravity on objects within a defined area. They can be used in scientific experiments, educational demonstrations, or for entertainment purposes in virtual reality simulations. Additionally, gravity discs can be used in training simulations for astronauts and pilots to experience different gravitational conditions.

The center of gravity in a rocket should be located slightly forward of the center of pressure to ensure stability during flight. This ensures that the rocket travels in a straight path without tumbling or veering off course. Placing the center of gravity in the correct position helps the rocket maintain control throughout its flight trajectory.

Gravitational Theory is the theory that any two particles of matter attract one another with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Basically the question is wrong or the concept of gravity in your brain is wrong, as gravity exists both at moon and earth, but the value of "g" varies as at earth it is 9.81m/s^2, and at moon it is some what around 1.8m/s^2.
