In nuclear physics and particle physics, the weak interaction, weak force or weak nuclear force, is one of the four known fundamental interactions, with the others being electromagnetism, the strong …

Sep 30, 2021 · The weak nuclear force, or weak interaction, is one of the four fundamental forces of nature – the other three being the strong nuclear force, electromagnetic force, and gravitational force.

In the Standard Model of particle physics, the weak force is carried by subatomic particles called W and Z bosons. By changing quarks to other types of quarks, the weak force converts protons into …

weak interaction, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that …

Oct 14, 2025 · The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all. The weak nuclear force is a key variable in particle physics.

Oct 15, 2019 · The weak nuclear force is one of the four fundamental forces of physics through which particles interact with each other, together with the strong force, gravity, and electromagnetism.

Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity holds stars together and keeps us on the ground.

T he weak interaction is responsible for some nuclear phenomena, such as beta decay, which can be understood as the weak force operating on the quarks within the neutron. One of two down quarks …

While the weak nuclear force is much weaker than the strong nuclear force, which holds the protons and neutrons together in the nucleus of an atom, it plays a crucial role in maintaining the balance …

The weak nuclear force (or just the weak force, or weak interaction) acts inside of individual nucleons, which means that it is even shorter ranged than the strong force.
