Why is the law of gravitation so similar to Coulomb s law

Being able to ask such a question shows that you are very studious! But even a teacher can have a hard time with this...

If there is a reason why they are so similar, it may simply be a coincidence in nature, but if you think about it, the coincidence is nothing more than saying that they are similar in form. The gravitational force is proportional to the product of the masses of two objects and inversely proportional to the square of the distance; The Coulomb force is directly proportional to the product of the charge at two points, and the square of the same distance is also inversely proportional. Both laws study the forces of two objects of similar nature to each other, and naturally, they must be related to both, so what is confusing is the inverse law of force and distance.

In Coulomb's law, the force between two point charges is due to a magnetic field of a certain strength generated around the point charge, and the force between them is essentially the action of the magnetic field force. So is gravitational force also an action of a magnetic field force? It seems hard to connect and hard to understand.

Because this does not seem to fit the concept of magnetic field in our cognitive theory of electromagnetism, because the magnetic field we know is a concept with polarity. However, from the unity of nature and various phenomena, it is inferred that gravitational force should be the effect of a magnetic force. This magnetic field is intrinsic to the object, it is the inherent magnetism between all objects, and it is a non-polar attraction.

Only in this way can we fully and appropriately explain the various phenomena related to the universe and nature.

This is precisely the connection between the electromagnetic force and the gravitational force, the macroscopic and the microscopic connection.

This is the very scientific fortress that today's scientists are trying to overcome.

Scientists want to explain the world with a grand unified theory.

It is now generally accepted that there are four forces: gravitational, electromagnetic, strong, and weak. Scientists are trying to find a unified equation that can include all four forces, but so far they have not succeeded.

You can do some research in this direction in the future.

The last step to get through a theory ——— your question! Three of the four forces (electromagnetic, strong, weak) have been unified, and the unification of gravitational and electromagnetic forces is being studied.

Coulomb's law and the law of gravitation.

The form of the formula is very close, mainly to mean that they are both inverse square laws, which is due to the fact that the virtual photons that transmit the electromagnetic force and the virtual gravitons that transmit the gravitational force are both medium bosons with a 0 rest mass, which is what the two have in common, and it is this that leads to the fact that both are inverse square laws.

But in essence, there are major differences between the two, first of all, the "charge" caused by the difference is that the gravitational force is caused by mass, and the electromagnetic force is caused by electricity; Second, the radiation mode of the two is different, the lowest polar radiation of the electromagnetic force (and often the strongest of all its radiation) is dipole radiation, and correspondingly, the spin of the photon is 1; The lowest pole radiation of gravity is 4 pole radiation, and correspondingly, the spin of the graviton is 2Again, the electromagnetic field is a linear field – photons do not produce secondary photons; The gravitational field is a nonlinear field - the graviton also has mass (this refers to its dynamic mass, not static mass), and it produces secondary gravitons, so in the case of strong gravitational force, the law of gravity will deviate far from the inverse square law, and the best modern theory of gravity can only be used - general relativity.

to deal with the problem, Newton.

The theory can no longer be used at this time. Of course, in the case of extreme proximity, the electromagnetic force will also deviate from the inverse square law, which is quantum mechanics.

Problems to be dealt with.

The law of gravitation is true. Isaac Newton published the law of gravitation in his 1687 Principles of Mathematics in Natural Philosophy. Newton's law of universal gravitation is formulated as follows:

Any two particles are attracted to each other by a force in the direction of the line. The magnitude of the gravitational force is directly proportional to the product of their masses and inversely proportional to the square of their distance, independent of the chemical composition of the two objects and the kind of medium between them.

Because scientists have found that Uranus, which is far away from the Sun, is not bound by the law of gravitation, scientists believe that if a case is proven to be false, then the law is presumed to be false, so it is false to say that the law of gravitation is false.

Because the theorem of gravitation is not entirely correct, it is not entirely true.

Coulomb's law and the law of gravitation are both laws that describe physical forces, but they differ somewhat in their vectoring. Coulomb's law describes the interaction force between the gods of charge, and the formula is: f = k * q *q ) r where f is the force between the charges, k is the coulomb constant, q and q are the magnitude of the charges, and r is the distance between the charges.

In Coulomb's law, the direction of the force is the same or opposite to the direction of the trillions of lines connecting the charges, i.e., along the straight line between the charges. The law of gravitation describes the gravitational force acting between objects and the formula is: f = g * m *m ) r where f is the gravitational force between objects, g is the gravitational constant, m and m are the masses of objects, and r is the distance between objects.

Similar to Coulomb's law, the forces in the law of universal gravitational forces also have the property of being in the same or opposite direction as the lines between objects. In summary, both Coulomb's law and the law of gravitation are vector laws, and the direction of their forces is related to the direction of the line between objects or charges. The forces in both laws are in the direction of a straight line between objects and either attract or repel each other.

But it is important to note that Coulomb's law describes the force of interaction between electric charges, while the law of gravitation describes the force of gravity between objects.

1. The law of gravitation was proposed by Isaac Newton.

2. The law of gravitation is an acre published by Newton in 1687 in the "Mathematical Principles of Natural Philosophy". This is a nourishment.

3. Newton's universal law of gravitation is expressed as follows: any two particles are attracted to each other by a force in the direction of the concentric line. The magnitude of this gravitational force is directly proportional to the product of their masses and inversely proportional to the square of their distance, independent of the chemical composition of the two objects and the type of medium in between.
