In particle physics, the weak interaction (the weak force or weak nuclear force) is the mechanism of interaction between sub-atomic particles that causes radioactive decay and thus plays an essential role in nuclear fission. Properties - Interaction types - Electroweak theory - Violation of symmetry. 24 Dec The weak force is one of the four fundamental forces that govern all matter in the universe (the other three are gravity, electromagnetism and the strong force). While the other forces hold things together, the weak force plays a greater role in things falling apart, or decaying. The weak interaction is responsible for radioactive decay, including the above Beta-minus decay. The weak interaction (the weak force or weak nuclear force) of particle physics is one of the four known fundamental interactions of nature, alongside the strong interaction, electromagnetism, and gravitation.

Weak force, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and. 7 Jun - 4 min - Uploaded by SciShow Hank continues our series on the four fundamental forces of physics by describing the weak. One of the four fundamental forces, the weak interaction involves the exchange of the intermediate vector bosons, the W and the Z. Since the mass of these.

25 Feb Abstract: The history of weak interactions starting with Fermi's creation of the beta decay theory and culminating in its modern avatar in the form. The weak nuclear force is the second weakest force, after gravity, and it is the force with the shortest range. It was first devised to explain beta decay. The weak force is so named because although it is stronger than gravity, it is only effective at very short distances ( m). Technically, it is one of the strongest. Weak interactions are responsible for the decay of massive quarks and leptons into lighter quarks and leptons. When fundamental particles decay, it is very. 1 Mar The weak force is what causes radioactive decay. It's also what has made life on Earth possible.

The most familiar manifestation of the weak interaction is nuclear beta decay and the most elementary beta -active nucleus is the neutron itself. The author. 28 Jun Some description and note of the significance of the weak interaction is given in the following quote taken from the press release for the The Weak Interaction.
