The weak interaction or weak force is one of the four fundamental forces and involves the exchange of the intermediate vector bosons, the W and the Z. The weak interaction responsible for some nuclear phenomena such as beta decay, which can be understood in terms of the weak force operating on the quarks within the neutron.One of two down quarks changes into an up quark by emitting a W – boson (carries away a negative charge). The weak force is so named because although it is stronger than gravity, it is only effective at very short distances (10-18 m). The W – boson then decays into a beta particle and an antineutrino.

Weak Interaction – Weak Force. Also called weak interaction. The weak force plays no role in the interaction of nucleons, though it is responsible for the decay of neutrons to protons and vice versa. The weak force allows the fusion of protons and neutrons to form deuterium. Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose.

The W and Z bosons that make the weak force weigh in at 80 GeV and 91 GeV respectively. The excess energy from this fusion is the source of heat from the sun. However, it also has the shortest range, meaning that particles must be extremely close before its effects are felt. The weak force is one of the four fundamental forces that govern all matter in the universe. Since these bosons are very massive (on the order of 80 GeV, the uncertainty principle dictates a range of about 10-18 meters which is less than the diameter of a proton. Gravity holds stars together and keeps us on the ground. 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. In nuclear physics and particle physics, the weak interaction, which is also often called the weak force or weak nuclear force, is the mechanism of interaction between subatomic particles that is responsible for the radioactive decay of atoms. The weak nuclear force is one of the four basic forces in nature, being weaker than the strong nuclear force and the electromagnetic force but stronger than gravity. Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. The weak interaction is one of the four fundamental interactions, and plays a role in processes such as beta decay. The Strong Nuclear Force (also referred to as the strong force) is one of the four basic forces in nature (the others being gravity, the electromagnetic force, and the weak nuclear force).As its name implies, it is the strongest of the four. Through the process of beta decay, it plays a crucial role in powering stars and creating elements. Compared to both electromagnetism and the strong nuclear force, the weak nuclear force has a much weaker intensity, which is why it has the name weak nuclear force. Technically, it is one of the strongest forces, but because the particles involved are so big, their travel is limited to the short distance listed above. The nuclear force is distinct from what historically was known as the weak nuclear force. The weak nuclear force is the second weakest force, after the force of gravity, and it’s the force with the shortest range.

Weak interaction, also called weak force or weak nuclear force, 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 fuels the Sun. It was first devised to explain beta decay, which was discovered by Ernest Rutherford in 1899 [1] (discussed in Chapter 6 ). A force that causes subatomic particles within the nuclei of atoms to decay or break up into smaller particles and to give off energy as radiation. There is an inherent left and right bias in the breakdown of particles involved with this force, which we'd notice if the Universe went all topsy-turvy. The weak nuclear force provides the one important exception. Gravity holds stars together and keeps us on the ground. The excess energy from this fusion is …
