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 an example of weak force?
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 are strong and weak 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 are the four weak forces?
Gravity, Weak, Electromagnetic and Strong.
What is the strong force in physics?
strong force, a fundamental interaction of nature that acts between subatomic particles of matter. The strong force binds quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons.
What is the weakest force?
gravity
Actually, 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.
How does a weak force work?
By emitting an electrically charged W boson, the weak force changes the flavor of a quark, which causes a proton to change into a neutron, or vice versa. This is what triggers nuclear fusion and causes stars to burn, according to CERN.
Why is gravity the weakest force?
The value of the gravitational constant (6.67 x 10–11) is very small. Therefore, the value of the gravitational force also becomes small. This makes the gravitational force the weakest force.
Why is the weak force called weak?
In fact, the force is termed weak because its field strength over any set distance the weak interaction is typically several orders of magnitude less than that of the electromagnetic force, which itself is further orders of magnitude less than the strong nuclear force.
Which of the following is weakest force in nature?
gravitational force
Among the 4 fundamental forces of nature, Gravity or gravitational force is the weakest force in nature.
What is the weak force in an atom?
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 are the 5 forces physics?
Or to read about an individual force, click on its name from the list below.
- Applied Force.
- Gravitational Force.

- Frictional Force.
- Air Resistance Force.
- Tension Force.
- Spring Force.
What are the 4 forces in physics?
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.
Which is strongest force?
The strong nuclear force
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.
How can we make a force stronger or weaker?
The strength of the electric force between two charged objects depends on the size of the charges and the distance between objects. The greater the charge, the stronger the force; the greater the distance between the objects, the weaker the force between them.
How do gluons hold quarks together?
The strong interaction is mediated by the exchange of massless particles called gluons that act between quarks, antiquarks, and other gluons. Gluons are thought to interact with quarks and other gluons by way of a type of charge called color charge.
Is gravity a weak force?
Gravity is a real weakling – 1040 times weaker than the electromagnetic force that holds atoms together. Although the other forces act over different ranges, and between very different kinds of particles, they seem to have strengths that are roughly comparable with each other.
What’s the weakest thing in the world?
Gravitational force, the weakest of the four forces, has a strength of 10 to the minus 40, relative to electromagnetism. The force of gravity (along with electromagnetism) has a range of infinity – every single atom in the universe is ‘gravitationally aware’ of every other atom.
What is the weakest force in chemistry?
the London dispersion force
The weakest force in chemistry is the London dispersion force. It is a temporary attractive force that is produced when electrons in two adjoining atoms occupy certain positions that lead to the formation of temporary dipoles. London dispersion force is also called as an induced dipole-induced dipole attraction.
What is weak force Class 11?
Weak force is the force existing between the elementary particles which are responsible for certain processes to take place at a low probability.
Why is the weak force important?
The weak force is tremendously important. Without it, there would be no life on Earth. The weak force causes radioactive decays, which are essential in making sunlight. Radioactive decays also warm the inner Earth, enabling liquid magma to move continents and generate earthquakes.
