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

基本相互作用（英語： fundamental interaction ）又称基本交互作用，為物质间最基本的相互作用，常稱為自然界四力或宇宙基本力（ fundamental forces ）。 迄今为止观察到的所有关于物质的物理现象，在 物理學 中都可借助这四种基本相互作用的机制得到描述和解释。

The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.

基本交互作用（英語： fundamental interaction ）又稱基本相互作用，為物質間最基本的交互作用，常稱為自然界四力或宇宙基本力（ fundamental forces ）。 迄今為止觀察到的所有關於物質的物理現象，在 物理學 中都可藉助這四種基本交互作用的機制得到描述和解釋。

In nuclear physics and particle physics, the strong interaction, also called the strong force or strong nuclear force, is a fundamental interaction that confines quarks into protons, neutrons, and other hadron particles. The strong interaction also binds neutrons and protons to create atomic nuclei, where it is called the nuclear force.

2024年12月27日 · 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.

There are four fundamental forces, sometimes called fundamental interactions. The forces are called fundamental because there is no simpler way for physicists to understand what the forces do or how they do it (their action ).

2024年9月13日 · 基本相互作用（英语： fundamental interaction ）又称基本交互作用，为物质间最基本的相互作用，常称为自然界四力或宇宙基本力（ fundamental forces ）。 迄今为止观察到的所有关于物质的物理现象，在 物理学 中都可借助这四种基本相互作用的机制得到描述和解释。

The strong force, as the name suggests, is the strongest of all four fundamental interactions. Three of the fundamental forces result from the exchange of force-carrier particles, which belong to a broader group called “bosons”.

2009年3月16日 · In physics, a fundamental interaction or fundamental force is a process by which elementary particles interact with each other. An interaction is often described as a physical field, and is mediated by the exchange of gauge bosons between particles. An interaction is fundamental when it cannot be described in terms of other interactions.
