Four Fundament force: Gravity, Electromagnetism, strong nuclear and weak nuclear forces.

The force of Gravity

Gravity is the universal force of attraction between all matter. one significant fact to know is that gravity is the weakest of the four fundamental forces. Gravity and gravitation can be used interchangeably. The universal law of gravitation illustrates the proportional attraction of objects to their masses while also demonstrating the inversely proportional relationship to the distance squared between them. Here Is the formula to better understand this concept:

Important notes

• Fg is the force
• upper case G is the gravitational constant where it equals 6.67*10^-11 Nm²/Kg²
• lower case g equals 9.8m/s²
• The unit for force is Newton(N)

Electromagnetic Force

The electromagnetic force is the force between charged particles(Coulomb's law)and moving charges(magnetic forces). One keynote is that electromagnetic force holds materials, molecules, and atoms together. let’s look at an illustration of Coulomb’s law:

Like Charges repel and unlike charges attract.

Here is the formula for the different properties of electromagnetic force:

Electric

Magnetic

• F stands for magnetic force
• q stands for the charge of moving particles
• v stands for the particle’s speed and direction
• B stands for the magnetic field

Electromagnetic(Electric +magnetic)

Strong Nuclear Forces

The strong nuclear force is the attractive force between protons and neutrons that holds the nucleus together against the repulsion from all protons. Here is an illustration to help you better understand how does everything works:

As you can see, the repulsions of protons ripped or strained the nucleus, but thanks to the strong nuclear force, the nucleus is able to stay together.

Weak Forces

Weak nuclear force holds/binds the neutron together. Due to the weak force, the neutron of unstable atoms automatically decay. As the neutrons spontaneously decay, an electron is released in the process known as beta or radioactive decay. Here is an illustration of the topic to further your understanding of the topic:

As you can see, due to the instability of atoms, the weak nuclear force changes protons to neutrons. in consequence, we have some radiation.

Conclusion

The four fundamental forces in nature are gravity, electromagnetism, strong nuclear, and weak nuclear forces. Gravity is the weakest of the four fundamental forces. The weak nuclear force is the second weakest of the four forces. The strong nuclear force is the strongest of the four forces. last but not least, the electromagnetic force is the second strongest. To be brief here is the rank of the forces from strongest to weakest: Strong nuclear force, electromagnetic force, weak nuclear force, and gravity. Each force contains its own unique properties. Gravity is the attraction between all matter. The electromagnetic force is the force between charged particles(coulomb’s law)and moving charges(magnetic). The strong nuclear force is what binds the nucleus together again the repulsion caused by the protons. Weak nuclear force holds the neutron together. Most importantly, the unit for force is Newton(N). When solving a problem dealing with gravity, you must remember that there is a difference between g and G. g is earth gravity and it equals to 9.8 m/s². G is the gravitational constant where it equals 6.67*10^-11.

Keynotes: — Like charges repel, but opposite charge attract.
