How Many Basic Forces Are There In The Universe
There are four fundamental forces. They are sometimes called universal forces. They are the strong nuclear force, the electromagnetic force, the weak nuclear force, and the gravitational force. Strong nuclear is the strongest force and gravity is the weakest.
Strong Nuclear Force
The strong nuclear force is one of the four fundamental forces in nature.
The Strong Nuclear Force is attractive and it is 'felt' between protons and neutrons that keep the nucleus together, and it is responsible for binding together the fundamental particles of matter to form larger particles. 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). As most people learn in their science education, like charges repel (+ +, or - -), and unlike charges attract (+ -). The strong force dies off with distance much faster than gravity or the electromagnetic force, so fast that it's almost impossible to detect the strong force outside of a nucleus. (The strong
force and the weak force are not inverse square laws.)
Electromagnetic Force
The electromagnetic force is a type of physical interaction that occurs between electrically charged particles. It is the force between charged particles, it acts between charged particles, and is the combination of all magnetic and electrical forces. Charges in motion produce magnetic force. Together they are called Electromagnetic Force. The electromagnetic force is responsible for most of the interactions we see in our environment today. The EMF (Electromotive force ) holds electrons in their orbit around the nucleus. These electrons interact with other electrons to form electron bonds among elements and produce molecules and, eventually, visible matter
Weak Nuclear Force
Newton’s Law of Universal Gravitation is used for magnetism, and gravitation and weak force is better understood by electroweak theory. The weak nuclear force is the second weakest force, after the force of gravity, and it’s the force with the shortest range. It was first devised to explain beta decay, which was discovered by Ernest Rutherford in 1899. Gravity holds stars together and keeps us on the ground. The effective range of the weak force is limited to subatomic distances and is less than the diameter of a proton. It is one of the four known force-related fundamental interactions of nature.
Gravitational Force
Newton’s Law of Universal Gravitation is used to explain the gravitational force. This law states that every massive particle in the universe attracts every other massive particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The gravitational force is the force that attracts two objects with mass.... including planets, stars, galaxies, and even light. In fact, every object, including you, is pulling on every other object in the entire universe! It is what decides how much we weigh and how far a basketball will travel when thrown before it returns to the surface. the gravitational force equals your weight. On a different astronomical body like Venus or the Moon, the acceleration of gravity is different than on Earth, so if you were to stand on a scale, it would show you that you weigh a different amount than on Earth.
