Soon after Eugene Wigner explained the nuclei as a consequence of two different nuclear forces. 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.

What is strong force example?
The examples of strong nuclear force are the force that binds protons and neutrons in nuclei of atoms. The elements heavier than the hydrogen atom. The fusion of hydrogen into helium in the sun’s core.
Which is the strongest force explain?
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.
Why is it called strong force?
The 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.
What is the strong force strength?
After turning on the LHC, scientists doubled their energy reach and have now determined the strength of the strong force up to 1.5 trillion electronvolts, which is roughly the average energy of every particle in the universe just after the Big Bang.
What is weak force in physics?
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 weak force example?
He pointed out that the fusion process in the sun, whereby hydrogen atoms glom onto one another to become helium, is an example of the weak force in action. A critical step in that reaction chain takes place through the weak force, so in fact the weak force drives the sun’s nuclear furnace.
What is the difference between strong and electric force?
Electric forces try to break the nucleus apart, while the strong nuclear force tries to bind the nucleus together. In larger atoms, the electric force of repulsion may break the nucleus apart, resulting in a form of radiation called alpha decay.
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.
Who discovered strong force?
In 1973, David Gross and Frank Wilczek, and independently David Politzer, discovered the key property of asymptotic freedom that underlies quantum chromodynamics, or QCD, the quantum field theory of the strong force – an achievement for which all three shared the 2004 Nobel prize in physics.
Why is the strong force short range?
Strong force: This is a short-range attractive force. “Short range” refers to the fact that the force dies off exponentially in distance. This means that a nucleon is only affected by the strong force of its nearest neighbors. However, within that distance of less than 2.0 E-15 m, it overwhelms the other forces.
What is the strong force in an atom?
The strong nuclear force is one of four fundamental forces in nature. The strong force is ‘felt’ between nucleons (protons and neutrons) inside of the nucleus of an atom. The strong nuclear force is sometimes referred to as just the strong force or the strong interaction.
What is the other name of strong force?
noun Physics. Also called nuclear force .
What does the strong force depend on?
The simple answer is that the strength depends on the range over which it is acting. At short distances the strong force is weak and at long distances it is strong.
How is strong force caused?
The strong nuclear force is created between nucleons by the exchange of particles called mesons. This exchange can be likened to constantly hitting a ping-pong ball or a tennis ball back and forth between two people.
What are the 4 types of forces?
fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.
Which is strongest force in nature?
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature.
What are the 4 forces?
Forces and carrier particles There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.
Where is the weak 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.
Which is the weaker force?
Gravitational force is the weakest force and having longest range as it exists between any two bodies in the universe.
Which is most weakest force?
Gravity is the weakest force and is less than one-millionth of a millionth of the strength of the strong nuclear force.
Is gravity or electric force stronger?
Here the difference is even worse. The electric force between these electrons is 2.40 x 1043 times bigger than the gravitational force. In other words, electricity is almost a trillion-trillion-trillion-trillion-trillion times stronger than gravity.
Is electric force strong?
Gravitational force and electrical force are two types of non-contact force. However, electrical force is significantly stronger than gravitational force.
How big is strong or force?
Explanation: Magnitude refers to the size or strength of the force. The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Was this answer helpful?
What force is against gravity?
Explanation: Normal force always acts perpendicular to the contact surface. It can act counter to gravity or to any other force that pushes an object against a surface. Think of normal force as the force that keeps a surface solid; without normal force, an object would pass right through a surface.
