Does science show that the gravitational constant is the same on different planets?

According to Newton's law of universal gravitation, we can understand it very clearly. The gravitational force of an object is proportional to its mass, and inversely proportional to the square of the distance between them. From this we can know that the more massive the object, the stronger the gravitational pull will be, and vice versa.

So, is the gravitational constant of a planet with a higher mass greater than a planet with a lower mass? It didn't, and as to why it did, we'll explain below. <>

Gravitational force: As the name suggests, it is the gravitational force that we often talk about in life, and his full name is: gravitational interaction force.

We think gravity is important because among the four forces, gravity was the first to be discovered and studied by human beings, and it is mainly displayed in the macroscopic aspect and the microscopic aspect is very little, almost nothing. Gravitational force is present all the time around us, and it is also called long-range force.

The most intuitive expression is the celestial bodies and planets in the sky that we rely on, and it just so happens that the movement of celestial bodies seems to be very mysterious, in the more popular words nowadays, it is a very tall thing, so we usually think that it is very important. <>

In fact, the fundamental explanation of gravitational force is a disturbance behavior of matter in space-time, which has a very clear explanation in Einstein's general theory of relativity, although the range of space-time disturbance will be far and wide, but when each matter is a gravitational source alone, his effect distance is not infinite, and there is a certain distance limit.

In fact, there is a difference between gravity and gravitational constant, and the constant of gravitational force is defined in the physics community as g:g is a fixed value. <>

The capital letter "g" is a coefficient prescribed by the scientist Newton, it has been given the meaning of "constant" in definition, in Newtonian mechanics, there is only this coefficient to represent the gravitational constant, even if the external world changes dramatically has nothing to do with him, so the gravitational constant is the same on any two planets.

The gravitational constant is the same on different planets and is represented in Newtonian mechanics, and there is only one and only one word number for the gravitational constant.

The gravitational constant is the same, but the weight on each planet is different, so the gravitational force is not the same. All conform to the law of gravity.

Same. The magnitude of this gravitational constant is g-valued.

The gravitational constant of each planet is different, because the volume of each planet is different, so its gravitational constant will change.

No, the gravitational constant is mainly related to the mass, radius, and rotation speed of the planet.

The gravitational force is directly proportional to the mass of the two objects and inversely proportional to the square of the distance between the two centroids. But this only applies if the two objects are out of a state of separation. For objects on the surface of the planet, the magnitude of gravity and density still have a certain relationship, because the denser celestial body, with the same mass, the volume of the dense is small, the distance between the object on the surface of the planet and the center of mass of the planet is close, and the gravitational force is larger, while the density of the planet is larger, the distance from the surface object to the center of mass of the planet is larger, and the gravitational force is smaller.

The surface gravity on a neutron star is very large, not because it is particularly massive, and in fact the star loses most of its mass in the process of forming a neutron star, but because it is so dense that the distance from its surface to its center of mass is much smaller than that of a planet of the same mass, and the gravitational force is inversely proportional to the square of the distance.

As for the relationship between mass and density, it cannot be said that the larger the planet, the greater the density, for example, Saturn is much larger than terrestrial planets such as Earth, but its density is smaller than that of water. Because its surface is gaseous. The surface of stars is also gaseous, so although they are huge, they are not very dense.

According to the formula, it is true that the higher the mass and density, the greater the gravitational force.

v=3/4πr^3

Planet volume = 3 4*pi*planet radius 3

m v Planet density = Planet mass Planet volume.

g=(g*m)/r^2

Gravitational acceleration = (g*mass of the planet) The radius of the planet 2 g is the gravitational constant.

>g=3/4*g*ρ*r

Gravitational acceleration = 3 4 * g * density * pi * radius.

g = (16 9 * (g 3) * (2) * (2) * m) f (citation) = gm = (16 9 * (g 3) * (2) * (2) * m) m (m represents the mass of the object).

Note: Gravity = autocentripetal force of the object + gravity of the object (the self-centripetal force is smaller, so in many cases it can be approximated as gravity = gravity).

Yes, "The Wandering Earth" released a few days ago, the earth was originally flying normally, and then came next to Jupiter (it seems to be Jupiter, I forgot a little), and then it was captured by Jupiter's gravity, causing the earth to be almost destroyed, so gravity has a lot to do with mass and density.

The greater the mass, the greater the gravitational force. The gravitational force between two objects, which is directly proportional to the product of the mass of the object, is inversely proportional to the square of the distance of the object. This is Newton's law of universal gravitation.

Yes. 1.Mass is directly proportional to gravity; 2.The higher the density, the smaller the distance. The square of the distance is inversely proportional to the gravitational force.

It is right that the greater the mass, the greater the gravitational force. It can also be said that the higher the density, the greater the gravitational pull. Why is it OK?

For example, when 100 bulbs are gathered together, the intensity of brightness goes up, but the range of brightness is smaller. If the 100 bulbs are spread out properly, the brightness range goes up, but the brightness intensity decreases. Then the higher the density, the greater the gravitational pull on the surface of the planet, but the gravitational radius will become smaller, which is also in line with the conservation of energy.

Another example is a 10-kilometer cloud, its gravitational force is at least 10 kilometers, if the 10-kilometer cloud is concentrated into a ping-pong ball, the gravitational force on the surface of the ping-pong ball is larger, but the gravitational range of the ping-pong ball cannot govern 10 kilometers.

If the planet simply becomes more massive, the gravitational pull will increase.

If the density of the planet increases, its gravitational pull does not become stronger, and the density of the planet becomes higher and it collapses inward.

If the density and mass increase, the gravitational pull will definitely increase.

In the case of equal distances, yes.

The higher the mass and density, the greater the gravitational pull.

The magnitude of the gravitational force is determined by the gravitational force:

This is for sure, this must be the bigger its strong field.

The higher the density, the greater the natural mass!

And the greater the mass, the greater the magnetic field!

The greater the magnetic field, the greater the gravitational pull!

"Is it only planets that have gravity? ”

No. Everything that has mass creates a gravitational pull on another thing that has mass.

All objects with a mass above a certain level have? ”

It doesn't need to go any further, as long as there is mass, there will be gravity, it's just a difference in size.

Is it because of the mass of building a ship as large as Earth, or a technological artifact like the Death Star, that they also have a gravitational pull? ”

Be. How much energy do you need to drive? ”

The key is how fast you want to drive it and whether you need to get rid of the gravitational constraints of some other massive object. For example, when there is no other object bound by gravity, you only want it to move from rest (i.e., the speed is only a little bit), and it is enough for the person to push it; But if you want it to reach the speed of the Earth's revolution around the Sun (30 kilometers per second), it would require joules (i.e. (1 2) (6 * 10 24) (3 * 10 4) 2), which is about the same amount of electricity generated by the Three Gorges Dam in 5 quadrillion (5 * 10 15) years! (See.)

As long as there is mass, there will be a gravitational force between objects, which is Newton's law.

The gravitational force that du is talking about, but if the mass is not large enough, this force is very small, it will not be felt at all, and most of the time it cannot be measured. Since the mass between the planets is large enough and the distance is suitable, this gravitational pull is obvious.

Build a large enough mass artifact and the gravitational pull will be noticeable as well. If you want to drive, you can calculate the minimum speed required to fly out of gravity according to the law of gravitation, and select the appropriate energy and drive according to the minimum speed.

The essence of gravity between stars is the rotation of the stars themselves, and when the rotation of the stars itself stops, the gravitational force will naturally disappear. The gravitational force between the planets is actually an ultra-long-distance distance force, and this kind of distance force cannot explain its origin and essence, so gravity is called a "mysterious force".

Newton once proposed the law of gravitation, Newton believed that all objects have gravity, but the size of this gravitational force is large or small, usually our human body may not feel this gravitational force, but it actually exists but is too small, so small that we can't detect it. Later, Einstein redefined it on the basis of Newton's gravitational force, which believed that gravity is a change in the elasticity of objects and masses in space, which may be bending or other changes in form. Although Einstein's definition is not perfect and confusing, scientists have been trying to find out what Einstein was trying to express.

Later, as the research of scientists became more and more in-depth, some scientists proposed that gravity is a force caused by the rotation of the planet, and when the planet stops rotating, the gravitational force will change. This also shows that the earth is currently rotating on its own, and when the earth's rotation stops, the gravitational force in the earth will disappear, and the gravitational force of objects in the earth will also disappear. But when the Earth starts to rotate again, this gravitational pull will be created again.

When scientists studied the interaction between the universes, they published the law of circular motion. In the law of circumference, they state that when a star is isolated in the universe, it is not disturbed by any factors, and it will keep its rotation without stopping. This law also shows that the rotation of a star does not require gravity or external force, but is an inertial motion.

At present, the rotation of the earth is also like this, it itself is not disturbed by other external factors and carries out a kind of rotation, but at the same time, if the earth is affected by the gravitational force of the sun, so the earth will revolve around the sun.

Gravitational force does not have an essence, because gravity is not matter, force is only acting in the force field, it is the performance of the energy poles relative to each other's cyclic motion and change, using motion to promote change, using change to complete movement, the distance of movement is balanced by the degree of change, the complete combination of its motion function and change mechanism, gravity is the combined force of all things, gravity is equal to gravity, there is no gravitational force between the planets, only a balance force.

The book "The Universe in the Whirlpool" explains the nature of gravity, which is a spiral force in the vortex, a spiral force that can spin atoms into stars.

Chen's Cosmological Model: The phenomenon of gravity is essentially formed by a static density gradient of dark energy (ether) energy density. That's all, and it has nothing to do with the pseudo-concept of space-time warping.

Einstein because the gravitational pull between planets is essentially a distortion of space-time, because the existence of the mass volume of an object changes the latitude of space near him.

The reason for the occurrence of gravitational force (brief description): When the high-energy particles moving in the universe pass through matter (celestial bodies or particles), part of them are intercepted and absorbed to form a weak energy region (Einstein's space-time curvature), which is the gravitational range mv2=e=mv2 (the formula of the law of conservation of energy conversion). For more details, please see the forthcoming gravitational hypothesis, "Elemental Periods and the Causes of Gravitation".

The essence of gravity is the mutual attraction between the materials of the planets, we all know that everything has a gravitational force, but the gravitational force is strong and weak.

The sun's glow and heat are not caused by nuclear fusion, but by gravitational focusing. This is the most convincing Copernican revolution. It was a major discovery that shook the scientific community. This is true of all shining stars. This is an indisputable truth.

Gravitational force is the magnetic field on the earth, and the earth has a magnetic field. If there is some substance inside, then there can be gravity, and people can be sucked into it.

The essence of gravity is the mass effect!

There is a high probability that there is a major misreading of the nature of gravity.

The existing theory of gravity holds that any two objects in nature are attracted to each other (this is human habitual thinking), and the general theory of relativity nonsensically believes that an object will bend the space-time around it, gravity is a manifestation of the curvature of space-time, there is a gravitational field around the object, gravity propagates in the gravitational field through gravitational waves, and there is an omnipresent graviton in the universe.

The existing theory of gravity ignores another very important possibility: the mutual attraction between objects is only a appearance, and its essence is the pressure difference between the outer cosmic space of the object. The new theory of ether believes that there is a huge etheric pressure in the universe (which may be hundreds of billions of times the atmospheric pressure in order of magnitude), and when the etheric pressure is transmitted between the ether particles in the universe through the object, the atomic nucleus in the object blocks the transmission of part of the ether pressure, and the pressure difference will occur, which is the essence of gravity.

We can take stars as an example to think about "is gravity a mutual attraction, or is it a transmission difference of external pressure in the universe?" "A star is a celestial body that gathers due to gravity, and the nuclear reaction at the core of the star is caused by the tremendous pressure, and the closer you get to the center of the star, the greater the pressure.

If gravity is the mutual attraction between objects, then the closer to the center of the star, the attraction at the center of the star is canceled out by the opposite direction of attraction from the surrounding areas, and the attraction at the center of the star is the smallest, even if the gravitational difference from the periphery is transmitted to the center of the star, the pressure at the core of the star is difficult to meet the conditions for nuclear reactions; Even if a nuclear reaction occurs, this pattern of mutual attraction will not be able to stabilize the equilibrium with the tension generated by the nuclear reaction inside, and the star will soon be **. On the contrary, if the gravitational force is an external pressure, the huge etheric pressure will gradually be transmitted from the periphery of the spherical star to the center of the star, and the internal pressure will increase in progression, and the pressure in the core of the star is enough to meet the conditions for nuclear reactions. Therefore, the essence of gravity is most likely to be the transmission difference of external pressure in the universe. 丨.
