Is there a limit to gravitation? What is gravitational force?

From the current point of view of physics, no.

Probably not, unless you're off Earth, uh, you can look it up on the encyclopedia.

Newton said, "The law of gravitation is the law of gravity that explains the interaction between objects." ”

The magnitude of the gravitational force between two objects is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between the two objects, and has nothing to do with the chemical nature or physical state of the two objects and the intermediary matter.

The formula is: f = ( g * m1 * m2 ) r 2f: the gravitational force between two objects.

g: gravitational constant.

m1: The mass of object 1.

m2: The mass of object 2.

r: The distance between two objects.

Einstein's theory of general relativity says that gravitation is the manifestation of the motion of an object in curved space.

i.e. Newton was wrong. The attraction of objects to each other is not due to gravitational attraction, but also due to the deformation of space by the mass of one object, which causes another object to move towards it; It's as if a well has been formed in the ground. If this object is moving at high speed, it is moving around it.

It's like a motorcycle moving around the wall of a well without falling.

What does gravity say?

Exist. Because gravitational force is caused by the mass of the object, as long as there is mass, there will be gravitational force, so gravitational force exists.

Gravitation does not exist, because the universe naturally does not have any gravitational force, but the spiral rotation of the planets in the universe causes the movement of planetary matter to attract to the core of the planet.

Gravitation exists, and the reason why we can stand on the ground and not fly is because of the existence of gravity.

More than 300 years ago, the British scientist Isaac Newton discovered that all objects have an attractive force, called "gravitational force", also known as "gravity". The greater the mass of the object, the greater the gravitational force, and the strength of this gravitational force is also related to the distance of the object, the closer the object is, the stronger the gravitational force. The earth's gravitational pull, also known as gravity, "sucks" us to the ground so that we can sit or stand smoothly.

The Moon is smaller than the Earth, so the Moon's gravitational pull is also smaller than that of the Earth. In space, the distance of various celestial bodies is very far, so the gravitational pull is weak, and the reason why astronauts can float in space and walk in space is because they are in a "gravityless state".

What does gravity say?

It is the gravitational force, which is one of the four basic interactions in nature.

The four basic functions include: universal inducing reed force, electromagnetic interaction, weak interaction, and strong interaction.

At present, the electromagnetic action and the weak phase excitation interaction have been unified, but the gravitational effect has not been found to be related to any other effect, it is independent.

The force by which two objects are attracted to each other is called gravitational force.
