Why does everything have a gravitational pull?

Gravitational attraction of all matter, the attraction of attraction to each other, is related to the mass volume of the object. Objects that are too close together will produce a certain repulsive force.

Why does gravity arise, Newton discovered the problem of gravity, it was he who was smashed on the head by an apple while thinking about the problem. The question of gravity comes to mind.

But there is currently no explanation as to why gravity arises.

The generation of gravity is linked to the generation of mass, and mass is an effect produced by the change of space, which arises by the production of mass attached to gravity.

2。Yes. According to the current theory, all matter is composed of photons, but photons have no mass, but matter still has its static mass, which means that photons must reflect static mass in a certain state.

It is said that the photons are constantly moving. When a photon is in motion, it exhibits the dynamic mass of a photon, which reflects the static mass of the object.

The presence of gravitational force between objects was discovered by scientist Isaac Newton. This is a conclusion that combines practice and theory. For example, like the twisted scale experiment, this conclusion is not easy to understand directly from the front, but it will be understood slowly if you think about it without focusing on the experimental conclusion.

Gravitation – the fundamental force of all things.

Each object occupies space, causing varying degrees of spatial distortion to create a gravitational pull.

Not all matter has gravity in it, but all matter has a trace of gravity.

According to the law of gravitation.

In nature, any two objects are attracted to each other, and the direction of gravity is on their lines, and the magnitude of the gravitational force is directly proportional to the product of the masses of the two objects, and inversely proportional to the square of their distance.

That is, as long as there is mass, there is gravity. Gravitational attraction is one of the fundamental properties of mass.

Stones have mass, so stones have a gravitational pull on objects with mass. The earth has mass, so the earth is against the moon.

Posture and gravity; The reverse is also true. The Sun has a very large mass, so the Sun is on the Solar System.

All planets and interstellar matter have a gravitational pull.

A plant has mass, and it also has a gravitational pull on other objects around it.

But in nature there are four fundamental forces.

, gravity is the weakest, so gravity is difficult to observe between the objects around us. For example, there is no gravitational attraction between two buildings, between a tree and a small grass next to it.

The law of gravitation formula.

Yes, there is gravity. Due to the different materials, the gravitational force produced by the different sizes is also different.

Definitely. Newton's law of gravitation has already illustrated this conclusion.

Gravitational force, Coulomb force between charges.

Gravitational force is the curvature of space-time by the mass of the object itself, not by the mutual pull of the gravitational field.

Therefore, gravity is not the force we often understand, but is formed by the curvature of space-time. It is mainly related to cosmic pressure, cosmic velocity, space dimension, magnetic field strength, and object structure.

Question 1: Why does gravitation exist? First of all, the current universe is mainly manifested by gravity, because the universe is now in a period of expansion, and all the universes will be affected by centrifugal force, and in order to balance this centrifugal force, gravitational force is generated.

When the universe is in a period of contraction, everything in the universe exhibits universal repulsion. It's just a macroscopic statement, an objective law of the universe, and of course a theoretical explanation of why gravitation exists, Newton only said that there is a gravitational phenomenon, but why does it exist? It was not made clear at all.

The most common explanation is that the existence of mass excites the gravitational field, and due to the interaction of the fields, the two forces of attraction and repulsion are generated, and the assumption that the field is a matter that actually exists, which makes me think of whether the ether is real or not, and it is impossible to verify. Einstein said that because of the existence of mass, mass is the embodiment of energy, and because of the action of energy, it is the curved surface of space that is bent, and the surface itself is curved, and it is also normal for the object to move around him, because his own orbit is curved, which seems to make sense and has defects.

Hope Question 2: Why does the earth have a gravitational force according to the magnitude of this gravitational force is proportional to the product of their masses and inversely proportional to the square of their distance, independent of the chemical nature or physical state of the two objects and the intermediary matter. The law of gravitation is the one that explains the interaction between objects.

Question 3: Why is there gravitational force on Earth According to classical physics, as long as there is mass, gravity will be generated.

Using the law of gravitation that Newton figured out, we can accurately calculate the magnitude of the gravitational force between two objects. But why there is gravitational force, Newton can't say.

It wasn't until Einstein came up with a general theory of relativity that he figured out the ** of gravity. Albert Einstein said that all masses will be deformed into space, just like putting an iron ball on a taut sheet, the iron ball will sag, and the objects located in this sunken area will move in the center of the sunken area until they collide with the iron ball. Planets in the universe will also "sag" the foundations of the space wheels near them.

So Einstein said that there is no such force as gravity at all, there is only the deformation of space. The motion of an object under the gravitational pull is simply its motion in the deformed space.

Question 4: Why does the earth have a gravitational pull? The earth has mass, and physics has a formula f=gmm r squared. f=magnitude of force g=constant m=mass of the earth m=mass of an object r=radius of the earth Typing is very hard, give the best, thank you.

As for the topic of whether everything really has gravity, I personally believe that everything that is visible in space will have gravitational physics. Why?

Because all the visible physical matter in the space of the solar system is the embodiment of the continuous accumulation and growth of the dust particle flow material released from the continuous combustion of the star (sun) to form a phased form, the end of the dust particle flow material is the structure of the atom, and the atom is composed of many electrons located in the periphery of the atomic nucleus, and the natural movement of the electron group around the atomic nucleus will naturally produce the magnetic physical phenomenon of matter. That is to say, among all the visible physical substances in the solar system, there are congenital magnetic physical phenomena of different sizes, and the larger the volume and mass and the denser the visible object, the stronger the magnetic strength it has, and the smaller the volume, mass and density, the weaker the magnetic property of the visible object.

One is the phenomenon of magnetic attraction between objects and objects; The second is a large volume, mass and dense object, which has a circular traction phenomenon that occurs when the magnetic field range rotates.

The gravitational pull of all things is not that the object macrocosm produces the gravitational force, but that all the particles in the universe that make up matter have a gravitational pull. This gravitational pull is not the function and property of this particle, but the life form in which this particle exists, and the force is his life, just as man must breathe and eat in order to live. The planets of the solar system revolve around the sun, the stars of the Milky Way revolve around black holes, and even the fact that you can stand firmly on the earth is due to him.

The particles are nanoscale, billionths of a meter. The gravitational pull of each particle is insignificant, but the infinite number of particles make up the sun. A strong gravitational pull is also formed.

These two different gravitational phenomena are randomly generated and embodied in visible objects that exist in the solar system's space. Therefore, everything that is visible in space will have gravitational physical phenomena. I wonder if this answer is accurate?

Everything in the universe has gravity, but why does it occur? What is its essence?

Yes. Because as long as there is mass in the object, there will be gravitational force, and there is no distance limit, so there will be gravitational force between all things.

There is no gravitational attraction between electrons and electrons. It behaves as a repulsive force, so gaps between atoms are formed.

Yes, just like the celestial bodies in the solar system, there is gravitational pull between the planets, and without gravity, the stars would not move in a circle around the sun.

Yes, because in physics, everything on Earth will be affected by the gravitational pull of the Earth, so there will be gravity between all things.

Everything flows, everything moves and changes, and if there is movement, it is powerful, and it is powerful! What is called force, force is naturally interacting, so it is called interaction force. Where does the force come from a stone itself?

Yes. It is attractive and repulsive in itself. If the gravitational force is greater than the attraction, it becomes sediment.

It is also a stone, which shows that the attraction and repulsion are basically balanced. Therefore, there must be a gravitational force and there must be a repulsive force. Otherwise, they will all be attracted into a piece!

So there is gravitational force, and there is absolutely universal repulsion. We can't just see gravity and not talk about it. The apple will fall to the ground, and that is because it can naturally grow on the tree first!

There is a fall, there is a rise!

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

Gravitational force The force of attraction of all matter to each other, i.e., the gravitational force, is related to the mass of the object, and the formula is: f=gmm r 2Why gravitational force arises, Newton discovered the problem of gravitational force because he was smashed on the head by an apple while thinking about the problem (most likely apocryphal).

The question of gravity comes to mind.

But there is currently no explanation as to why gravity arises. Modern physics (general relativity) believes that gravitational attraction is caused by the curvature of space-time, and that the curvilinear motion in the universe is a linear motion in four-dimensional space-time.

The generation of gravity is linked to the generation of mass, which is the intrinsic property of matter, an effect produced by the change of space, and the emergence of gravity attached to the creation of mass.

The law of gravitation: The gravitational force between two objects is directly proportional to their mass and inversely proportional to the square of the distance. i.e. f=gmm r 2 and g is the gravitational constant which is n*m 2 kg 2

Different interpretations of what gravity is under different views of space-time:

Gravitational attraction is considered one of the fundamental forces in the universe in classical physics, and is directly proportional to mass and inversely proportional to distance. But in Einstein's theory, gravity is no longer a fundamental force, but only a manifestation of the bending of the structure of space-time. The reason for the bending of runaway structures is the huge mass.
