Fundamental forces
The four fundamental forces of nature are, in order: weak interaction, strong interaction, electromagnetism and gravity. The term "fundamental" refers to the fact that they are the oldest known physical interactions. For example:
Weak interaction
The weak interaction is responsible for radioactive decay, nuclear fusion and fission. It also causes beta decay (decay by emission of an electron or positron) and gamma-ray bursts.
It involves the exchange of quarks with gluons in a process called gauge interactions. Gluons bind quarks together to form hadrons such as protons and neutrons which then combine with one another to form atoms or molecules when heated sufficiently.
Strong interaction
The strong interaction is the strongest force of nature. It is the glue that holds protons and neutrons together in the nucleus, allowing you to have atomic nuclei.
The strong nuclear force binds protons (positive charges) and neutrons together, making them easier to detect as they move through gas clouds or interstellar space. It also causes changes when two particles are close enough—for example, if you smash two hydrogen atoms together with a hammer, they'll break apart into their component parts before they can fuse back into a new atom.
Electromagnetism
Electricity and magnetism are two fundamental forces.
Light is an electromagnetic wave, or a type of wave that travels at the speed of light or 186,000 miles per second (299 km/s). When you shine light on something, it makes the object vibrate in response to an electric field produced by your body—this is known as electrostatic charge.
Both electricity and magnetism can be used to transport energy from one place to another through wires or conductors. The most common example is electricity powering a television remote control; however, it may also be used for other purposes such as lighting up houses during power outages when there isn't enough sunlight available for solar panels to generate enough electricity
Gravity
The gravitational force is the weakest of all fundamental forces, but it still has a powerful effect on our lives. Gravity is what keeps us on the ground and prevents objects from floating away into space. It's also responsible for keeping moons in orbit around planets, keeping stars held together by their own gravity and keeping galaxies rotating around one another.
The amount of mass in an object determines how much gravity it experiences—the bigger something is, the more its gravitational pull will be felt by other objects nearby (or far away). So if you were to drop a cannonball onto Earth's surface from outer space there would be no way for it to float off into orbit because there are too many nearby bodies for that to happen: if you set up a cannon with its barrel pointing straight up into outer space then pulled back on one end until just before firing then released again...
The four fundamental forces of nature.
The four fundamental forces of nature are:
Weak interaction (W), which is responsible for Yukawa's exchange principle.
Strong interaction (S), which includes the strong and weak nuclear force as well as other types of interactions between subatomic particles in nuclei through electroweak symmetry breaking, such as gluon fusion and quark-gluon plasma formation.
Electromagnetism (E), which is responsible for light emission and absorption by matter at a particular frequency range called the visible spectrum that can be used to measure distance or motion relative to an observer through action-at-a-distance phenomena such as relativity theory or quantum entanglement theory; it also plays an important role in explaining magnetism because electrons have spinning magnetic fields around them that generate electric currents when they interact with other charges within atoms causing them to emit photons when they move around those charged particles
Conclusion
There are four fundamental forces of nature. The first two are weak and strong interactions, while the other two are electromagnetism and gravity. All four of these forces have been studied in great detail by scientists, but they can also be explained using other models or theories that go beyond what we know today about physics. However, we believe that these four forces play an important role in shaping our universe as well as how everything in it works together.
