In physics, the fundamental interactions or fundamental forces are interactions in nature that appear not to be reducible to more basic interactions. There are four fundamental interactions known to exist: [1] gravity; electromagnetism; weak interaction; strong interaction

fundamental force, in physics, any of the four basic forces— gravitational, electromagnetic, strong, and weak —that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.

Mar 1, 2016 · Fundamental Interactions These are the most basic interactions in physical systems. There are four conventionally accepted fundamental interactions: Gravitational, Electromagnetic, Strong force, and Weak force.

Dec 23, 2021 · Facts about the four fundamental forces that describe every interaction in nature.

At the most fundamental (microscopic) level, physicists today believe that there are only four (or three, depending on your perspective) basic interactions: gravity, electromagnetism, the strong nuclear interaction (responsible for holding atomic nuclei together), and the weak nuclear interaction (responsible for certain nuclear processes, such ...

fundamental interaction, In physics, the effect of any of the four fundamental forces—gravitational, electromagnetic, strong, and weak. All known natural forces can be traced to these fundamental interactions.

Aug 9, 2000 · Two new forces are introduced when discussing nuclear phenomena: the strong and weak interactions. When two protons encounter each other, they experience all four of the fundamental forces of nature simultaneously. The weak force governs beta decay and neutrino interactions with nuclei.

There are only three fundamental forces responsible for all interac-tions among elementary particles.1 Each of these interactions (electro-magnetic, weak, and strong) has its own characteristic range and char-acteristic interaction time which determine the likelihood that a given elementary particle reaction will occur. These characteristic ...

In physics, a fundamental interaction or fundamental force is a mechanism by which particles interact with each other, and which cannot be explained in terms of another interaction. Currently, it is believed that there are four fundamental interactions: Strong interaction, weak interaction, gravitation, and electromagnetism .

Fundamentally, both magnetic and electric forces are manifestations of an exchange force involving the exchange of photons. The quantum approach to the electromagnetic force is called quantum electrodynamics or QED.
