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.
There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.
The electromagnetic and gravitational interactions have an infinite range. The weak force has a range of up to 10 –18 m. The strong force has a range of ~ 10 –15 m. The fundamental interactions in order of strength. The gravitational interaction only affects particles with mass.
6 wrz 2024 · Strong force, a fundamental interaction of nature that acts between subatomic particles of matter. The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons. It also holds together the atomic nucleus and underlies interactions between.
At the most fundamental level, the strong force is an exchange force between quarks mediated by gluons. The use of Feynman diagrams to visualize the strong interaction involves primitive vertices with quarks and gluons.
The Strong Force. A force which can hold a nucleus together against the enormous forces of repulsion of the protons is strong indeed. However, it is not an inverse square force like the electromagnetic force and it has a very short range.
The strong nuclear force is an attractive force that exists between all nucleons. This force, which acts equally between proton-proton connections, proton-neutron connections, and neutron-neutron connections, is the strongest of all forces at short ranges.
