Gravitational interaction. All particles participate in it. Presumably carried out by gravitons. The weak interaction is about 10 ^ 36 times more intense than the gravitational one if the distance between the interacting particles does not exceed 10 ~ 17 m. Weak interaction exists between quarks and leptons, as well as between leptons. Carried out by intermediate upper bosons. Electromagnetic interaction is about 10 times more intense than weak interaction. Long-range interaction. It is carried out between electrically charged particles due to the exchange of photons. Nuclear interaction occurs only between hadrons. Approximately 100 times more intense than electromagnetic interaction if the distance between particles does not exceed 10 ~ 15 m. Short-range interaction. It arises due to the exchange of pions between nucleons.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
