What Are the Four Fundamental Forces of Nature?

The four basic forces, namely the four basic forces in nature, strong nuclear force, weak nuclear force, electromagnetic force, and gravity, can be unified through the field.

Gravitational attraction of all matter, mutual existence, is related to the mass of the object. If the object is too close, it will produce a certain repulsive force. Why did gravity occur? Newton discovered the problem of gravity. He was hit by an apple on his head while thinking about it. Think of gravity. However, there is no explanation for why gravity is produced. The generation of gravity is related to the generation of mass. Mass is an effect produced by changes in space. Law of gravity: The gravitational force between two objects is proportional to their mass and inversely proportional to the square of the distance. Gravity is the force that a particle attracts to other particles and is itself subjected to.

The gravitational force between two objects is proportional to their mass and inversely proportional to the square of the distance. That is, F = GMm / R ^ 2, G is the gravitational constant and is 6.67 * [10 ^ (-11)] N * m ^ 2 / kg ^ 2.
