There are four fundamental forces of nature. The four forces are the gravitational force, the electromagnetic force, the weak nuclear force and the strong nuclear force. These four forces have strengths, and the Strong Nuclear Force is the strongest, but has the shortest range. Then it would be the Electromagnetic Force which is strong and has infinite range. Next is the weak nuclear force which is weak, but has a short range. Finally, the gravitational force is the weakest, but has an infinite range. Say no to plagiarism.

This force is the weakest, but has infinite range. Gravitational force is the type of force that would pull any two objects and use mass to pull them together. We call the gravitational force “attractive”. The reason we call it attractive is because of all the mass it attracts. One thing gravitational force never does is separate masses, but always brings them together. Then there is the electromagnetic force which is strong and has infinite range. Since this force has infinite reach, it affects everything in the universe. This force has the special ability to not only attract charges, but can also repel them. Since the Electromagnetic Force has infinite range, you would think it is weak, but it is actually very strong. Now I'll give you an example that blew my mind and I'll tell you how strong the electromagnetic field actually is. The electromagnetic field is 1,000,000,000,000,000,000,000,000,000,000,000,000 times stronger than Earth's gravity and that's crazy. To give you an example of when the electromagnetic force affects you is when you rub your hair on a balloon and it attracts: this is the electromagnetic force. The weak nuclear force is as weak as its name suggests and has a short range. The weak force is definitely stronger than gravity, the only reason we call it the weak nuclear force is because it has a short range. To give you an example of the weak force would be Beta Decay. What happens during beta decay is that neutrons start to disappear and because of this they are replaced by protons etc... and this is a short description of beta decay and this is an example of weak nuclear force. What would happen if we didn't have the weak nuclear force? Would it change anything? Yes, many things would change, some things would become more stable. Even the sun would not exist because the weak force creates and allows protons and electrons to form and create an element which is the source of the sun. The strong nuclear force is the strongest, but has the shortest range of all forces. The Strong Nuclear Force is the force that unites protons and neutrons and makes them an atomic nucleus. The Strong Nuclear Force is the most powerful: it is 100 times stronger than the Electromagnetic Force. The main goal of the Strong Nuclear Force is to bring neutrons and protons together and that's pretty much all it does. Please note: this is just an example.

I told you about their strengths and what their purposes are in the world today. Without these forces we would not be alive. I think the four fundamental forces are very interesting and I think everyone should look at them. The reason I think they are so fascinating is because it gave me a chance to make comparisons about how they are different from things on earth.
