Weak nuclear force class 11

The nuclear force is one of nature’s four fundamental forces, along with gravitational and electromagnetic forces. They are also known as strong forces since they are \(10\) million times stronger than chemical binding forces.Ernest Rutherford discovered the nucleus in an atom. He proposed that the nucleus is made up of nucleons (protons and neutrons), and \(99.9\%\) of the atom’s mass is concentrated in the nucleus. Now, a question arises! Though protons have a positive charge and repulsive electrostatic Coulomb force exists between protons, how do two protons stay in the nucleus? The answer is “Nuclear force”. There exists a stronger attractive binding force in the nucleus, which is nuclear force. Imagine two brothers’ proton \(1\) and proton \(2\) fighting over some family issue. They stay in the same house (nucleus) but want to separate from the family due to mindset mismatch (Coulomb repulsive force). They still decided to stay in the same place because of the mother’s strong bond with the children and her love (attractive nuclear force). This real-life example explains the role of nuclear force in binding nucleons in the nucleus. What are the range, types, and characteristics of Nuclear force? We will get the answers to all these questions in this article. Nuclear Force The four fundamental forces that make up the universe are electromagnetic force, gravity, strong nuclear force, and weak nuclear force. The basic concept of force is well-known. We must apply force to...

force even though it’s almost never described as one. Instead of a simple inverse square law like gravity and electromagnetism, it decays exponentially so that it weakens over a very short distance. But there’s one more piece to this puzzle. At the popular science level, no one ever explains what the equation for the strong nuclear force is, either. It does have one, and it’s simple enough to explain, but no one ever mentions it, which is a shame because it’s actually kind of cool. This equation is called the “ Here, α and σ are constants associated with the strong force. The main function of the strong force is that it holds the quarks inside a proton or neutron together. It holds atomic nuclei together, too, but that’s a side effect. The Cornell potential tells us how this works when we take a derivative to convert it to a force: The first part of this is an inverse square law. In other words, inside a proton or neutron constant. Regardless of the distance between them, two “unpaired” quarks will be attracted to each other with a constant force on top of the inverse square law of about 10,000 newtons [1] (which is a weirdly normal-sounding number equal to about one ton of force). Now, there are several caveats here. First is that this equation isn’t really for two quarks. It only works for the simplest system of an antiquark. Other mesons, which have charge, flavor, or mass differences between the quarks, and Second, there’s a sense in which this equation is not “exact” ...

The strong nuclear force pulled positively and negatively charged Strong Nuclear Force: Two positive charges repel each other because of the electromagnetic force, so the strong nuclear force lives up to its name by overcoming the intense repulsion between similarly charged particles that coexist in the nucleus of atoms. When the strong nuclear force that binds protons and neutrons in an atom is broken, extreme high-energy photons are released in the process. 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 ne...

I know that the But what exactly does the weak force do? Or to put it another way, why do we call it a force? Does it push the red particle of the picture away from the nucleus? Is it called a force only because it has some corresponding force particles? And if it is a force, what does it act on? I looked over at ' is a force or not. That is what I want to know, why do we include it in the four fundamental forces? $\begingroup$ Have you tried reading the Wikipedia article on the weak force? If you do maybe you can pick some pieces out that cause some confusion or narrow down what you want 8n your question, it would also be good to have some idea at what level you expect the answer to be at. Are you a student physics? $\endgroup$ $\begingroup$ The mathematics that describes elementary particles and forces of nature (one of which is the weak force) is called Quantum Field Theory. You should study the basics of QFT if you want to understand particles and forces. Analogies are misleading and babbling about virtual particles doesn't get you any closer to real understanding; only the math does. $\endgroup$ The weak force is one of the fundamental forces, but it doesn't have a strong attractive or repulsive effect on particles, and the term "weak interaction" is often preferred. For details on the attractions and repulsions associated with the weak interaction please see All of the fundamental fermions (i.e., quarks and leptons) are subject to the weak interaction. In contrast, t...

A particle physicist seeks to develop models of particle interactions. This work builds directly on work done on gravity and electromagnetism in the seventeenth, eighteenth, and nineteenth centuries. The ultimate goal of physics is a unified “theory of everything” that describes all particle interactions in terms of a single elegant equation and a picture. The equation itself might be complex, but many scientists suspect the idea behind the equation will make us exclaim: “How could we have missed it? It was so obvious!” In this section, we introduce the Standard Model, which is the best current model of particle interactions. We describe the Standard Model in detail in terms of electromagnetic, we...

So, let’s get started and learn through Physical World Class 11 Notes. Physical World Class 11 Notes PDF Free Download What is Science? The physical world describes that you can think of Science as the methodical endeavour of comprehending phenomena that occurs naturally around us. Since different laws of nature govern our surroundings, the knowledge gained in the process is utilized for predicting, correcting, and controlling these phenomena. In simpler terms, the objective of Science is to examine, test, and predict these phenomena around us. What is Physical World in Physics? In order to bring requisites changes to our surroundings, it is important to understand the way it works. This is done through Scientific methods which include several interrelated steps such as systematic observations, structured experiments, qualitative and quantitative reasoning, mathematical modelling, prediction, validation, or false theory. What is Physics? An important component of the physical world, Physics can be broadly explained as an exploration of the basic laws of nature and their appearance in various natural...

From strolling in the city to launching a rocket into space to sticking a magnet on your cupboard, physical forces are acting around us. In any case, every one of the forces that we experience consistently (and numerous that we don’t understand we experience consistently) can be trimmed down to only four principal forces: • Gravity. • The weak nuclear force. • Electromagnetism. • The strong nuclear force. These are known as the four crucial forces of nature, and they administer all that occurs in the universe. Gravity Gravity is the attraction between two items that have mass or energy, regardless of whether this is seen in dropping a stone from a building, a planet circling a star, or the moon causing sea tides. Gravity is likely the most natural and recognizable of the major forces, but at the same time, it’s been one of the most difficult to clarify. Isaac Newton was quick to propose the possibility of gravity, apparently propelled by an apple tumbling from a tree. He portrayed gravity as a strict attraction between two items. Hundreds of years after the fact, Albert Einstein recommended, through his hypothesis of general relativity, that gravity isn’t an attraction or a force. All things being equal, it’s an outcome of items twisting space-time. A huge article chips away at space-time somewhat like how an enormous ball put in a sheet influences that material, twisting it and prompting other, more modest items on the sheet to fall toward the center. However gravity hold...

Electron Capture & Electron–Proton Collisions • Electrons and protons are attracted to each other via the electromagnetic interaction • However, when they interact with each other, it is the weak interaction that facilitates the collision • Both electron capture and electron-proton collisions have the same decay equation • Electron capture is when an atomic electron is absorbed by a proton in the nucleus resulting in the release of a neutron and an electron neutrino • This decay is mediated by the W + boson • Electron-proton collisions are similar; when an electron collides with a proton, a neutron and an electron neutrino are emitted • This decay is mediated by the W – boson Ashika graduated with a first-class Physics degree from Manchester University and, having worked as a software engineer, focused on Physics education, creating engaging content to help students across all levels.
