The Strong Nuclear Force is an attractive force between protons and neutrons that keep the nucleus together and the Weak Nuclear Force is responsible for the radioactive decay of certain nuclei. It was realized that the strength of the two forces differed a lot. The typical ratio is of the order of 10 14 at ordinary energies.
What is strong nuclear force and what does it affect?
The strong nuclear force holds together the protons and neutrons in the nucleus of an atom. This is actually a side effect of its function binding quarks together to make the protons and neutrons themselves. The particle of the strong force is called the gluon because of the strong force’s glue-like properties. The strongest of the subatomic forces is the aptly named strong nuclear force. In ...
What is an example of the weak nuclear force?
While the strong force holds the quarks in a nucleon together (and as the residual strong force also holds the nucleons in the nucleus together), the weak force, which is carried by W+, W- and neutral Z bosons enables for example quarks to change their flavour, which can cause a neutron to turn into a proton releasing an electron and an electron anti-neutrino.
What does weak nuclear force mean?
weak nuclear force noun. One of the four fundamental forces that is associated with nuclear decay. Its gauge bosons are the W, W and Z particles.
What does weak nuclear force do?
Weak Nuclear Force: The weak nuclear force can change a neutron into a proton in a process called nuclear decay. When the weak nuclear force converts a neutrally charged neutron into a positively charged proton, sub-atomic particles are released near the speed of light.
What is a strong force in nuclear force?
The strong nuclear force is the force that holds protons and neutrons together. It also holds them all together in a nucleus and is responsible for the energy released in nuclear reactions, except for a much smaller portion due to the weak force, which is involved in beta decay.
Which nuclear force is weak?
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.
What is the strongest and weakest force?
Hence, gravity is the weakest, and strong nuclear force is the strongest fundamental force.
Which is the strongest and weakest nuclear force in nature?
The strongest force out of the fundamental forces is the strong nuclear force. It is the force which acts only on the particles within the nucleus; it does not depend on the distance and acts within the nucleus. The weakest force is the gravity.
Which is the strongest force?
There are four fundamental forces: Gravitational force, Electromagnetic force, Weak nuclear force and Strong nuclear force. Among all these four forces, Strong nuclear force is the strongest.

gravityActually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
Which is the weakest force and why?
Gravitational force is the weakest force and having longest range as it exists between any two bodies in the universe.
Why is gravity a weak force?
String theory requires that the universe has more than the three spatial dimensions that we experience, and possibly as many as 10. According to string theorists' best ideas, gravity is so weak because, unlike the other forces, it leaks in and out of these extra dimensions.

Which is the strongest force and why?
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It's 6 thousand trillion trillion trillion (that's 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website (opens in new tab).
What causes weak nuclear force?
Nuclear fusion This creates an unstable form of helium (2He), which has a nucleus with two protons, as opposed to the stable form of helium (4He), which has two protons and two neutrons. The next step is where the weak force comes into play. Because of the overabundance of protons, one of the pair undergoes beta decay.
Is Fission the weak nuclear force?
The strong force is responsible for both fusion and fission. Nucleons (protons and neutrons) are composed of quarks held together by the strong force. The nuclear force, also known as the residual strong force, binds nucleons to each other. So it's involved in both fusion and fission.
Which nuclear force is the strongest?
The strong forceThe strong force or strong nuclear force is one of the four fundamental forces of nature, along with gravity, electromagnetism and the weak force. As the name suggests, the strong force is the strongest force of the four. It binds fundamental particles of matter, known as quarks, to form larger particles.
Is radiation a weak force?
Beta radioactivity is the best known manifestation of the weak force. It's a slow process as it occurs with difficulty. Unlike nuclear forces and electromagnetism, the weak force can transform a neutron into a proton or vice versa, thus changing the composition of a nucleus.
Why is nuclear force strong?
The strong nuclear force holds most ordinary matter together because it confines quarks into hadron particles such as the proton and neutron. Moreover, the strong force is the force which can hold a nucleus together against the enormous forces of repulsion ( electromagnetic force) of the protons is strong indeed.
What is the term for the force that holds neutrons and protons together?
Residual Strong Force. The residual strong force , also known as the nuclear force, is a very short range (about 1 to 3 fm) force, which acts to hold neutrons and protons together in nuclei. In nuclei, this force acts against the enormous repulsive electromagnetic force of the protons. The term residual is associated with the fact, it is the residuum of the fundamental strong interaction between the quarks that make up the protons and neutrons. The residual strong force acts indirectly through the virtual π and ρ mesons, which transmit the force between nucleons that holds the nucleus together.
What is the weak interaction of neutrons?
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).
What is the weak nuclear force?
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. It is the force that allows protons to turn into neutrons and vice versa through beta decay.
Why is the weak force important in nuclear fusion?
Nuclear fusion has also been created in laboratories, and that process requires the weak force to work too.

What are the two fundamental forces?
The strong force and the weak force are two the four fundamental forces. They are very different. This article summarizes these differences.
How do neutrons help to reduce repulsion?
Also, the neutrons are a source of more strong force for the nucleus since they actively participate in the meson exchange. These factors, coupled with the tight packing of protons in the nucleus so that they can exchange mesons creates enough strong force to overcome their mutual repulsion and force the nucleons to stay bound together.
How does nuclear force work?
This is where the strong nuclear force comes in. The strong nuclear force is created between nucleons by the exchange of particles called mesons. As long as this meson exchange occurs, the strong force is able to hold the participating nucleons together. The nucleons must be extremely close together in order for this exchange to happen. The distance required is about the diameter of a proton or a neutron. If a proton or neutron can get closer than this distance to another nucleon, the exchange of mesons occurs, and the particles will stay together. If they can't get that close, the strong force is too weak to make them stick together, and other competing forces (usually the electromagnetic force) can influence the particles to move apart.
What holds protons and neutrons together?
The strong force holds protons and neutrons together in an atomic nucleus. It has a very short range. Each proton or neutron only feels the strong force from its immediate neighbors.
How does a neutron change into a proton?
Going back to radioactive decay, in a specific case called ‘beta decay’ a neutron in the nucleus is converted to a proton (N.B. this means one element changes into another). To conserve charge, an electron is created, which flies out of the nucleus. However, a (anti-)neutrino is also created, and it too flies out of the nucleus, carrying away some momentum. It can only do this because the weak force is available to transfer momentum — so this decay couldn’t happen if there was no weak force. The reverse process (protons changing to neutrons) is also possible, and indeed if it wasn’t then we’d be in big trouble: this process happens in the core of the sun when two hydrogen atoms combine to form deuterium (an isotope of hydrogen), the essential first step in the fusion reaction that produces the sun’s energy.
What is the boson of electromagnetism?
So, for electromagnetism, the relevant boson is the photon (N.B. not the electron, which is just a particular kind of charged particle). For the strong force, it’s the gluon (this particle mediates the force that binds quarks together to form e.g. protons, neutrons, mesons). For gravity, it’s the graviton (but note that this is currently undetected). Finally, the weak force actually gets the W+, W-, and Z bosons, which are all related and work together to mediate the forces involved in weak interactions.
Which process spits an electron and a neutrino out of the nucleus?
The best and longest known one is beta decay which is a process that spits an electron and a neutrino out of the nucleus changing a nucleus to a more positively charged one. The proto-typical example is neutron decay which
What is the strongest force in the universe?
The Strong Nuclear 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. However, it also has the shortest range, meaning that particles must be extremely close before its effects are felt. Apparently, its main job is to hold together the subatomic particles of the nucleus (protons, which carry a positive charge, and neutrons, which carry no charge. These particles are collectively called nucleons).
What is the force in the nucleus of an atom due to which the structure of an atom is stable?
The force in nucleus of an atom due to which the structure of an atom is stable is known as strong nuclear force.

Why is carbon 14 important?
The weak force is critical for the nuclear fusion reactions that power the sun and produce the energy needed for most life forms here on Earth. It's also why archaeologists can use carbon-14 to date ancient bone, wood and other formerly living artifacts. Carbon-14 has six protons and eight neutrons; one of those neutrons decays into a proton to make nitrogen-14, which has seven protons and seven neutrons. This decay happens at a predictable rate, allowing scientists to determine how old such artifacts are.
What is the weak force?
The weak force. The weak force, also called the weak nuclear interaction, is responsible for particle decay. This is the literal change of one type of subatomic particle into another. So, for example, a neutrino that strays close to a neutron can turn the neutron into a proton while the neutrino becomes an electron.
What percentage of the universe is dark matter?
Further complicating the story is the invisible realm of dark matter and dark energy, which make up roughly 95% of the universe. It's unclear whether dark matter and energy consist of a single particle or a whole set of particles that have their own forces and messenger bosons.
What are the two parts of electromagnetic force?
As its name indicates, the electromagnetic force consists of two parts: the electric force and the magnetic force . At first, physicists described these forces as separate from one another, but researchers later realized that the two are components of the same force.
