Caden McDonald Physics 1 3/9/20 The Fundamental Forces of Physics Introduction : In this report I plan to elaborate on the four different, fundamental forces of physics and nature. These being: the gravitational force, the electromagnetic force, the weak nuclear force, and the strong nuclear force. I will go into the history of each of these forces, noting the many scientific minds that helped discover it and others along the way that either changed theories or backed them as time went on. I will then explain some controversies behind the forces, if there are any, along with the applications these forces have on people and objects today. Gravitational Force : Gravity, in the large scale of all things, has been discovered quite recently. It was just discovered about three hundred years ago until it was finally discovered and proven. Before anything was discovered behind the phenomenon known as gravity, people such as the Greeks just believed that God willed the stars and planets to where they were. There was no rhyme or reason and they just believed all of the things to “be” as God had commanded it. Many people, before anything was discovered, believed in the geocentric model, or the model where Earth is the center of the universe. Questions were finally raised to this assumption with the findings of astronomers such as Galileo Galilei and Tycho Brahe in the 1500’s, who discovered that the Earth and the other planets, in fact, all revolved around the sun despite what people had believed at the time. Johannes Kepler then revealed that all the planets moved in an elliptical orbit, not a circular

orbit. These discoveries, important as they are, only raised more questions. What caused the planets to do this? That is where Sir Isaac Newton came in with his theory of gravity after an apple fell on him while he was thinking about the forces of nature. He first came with this idea by realizing that the moon should shoot off into space without a face keeping it orbiting the Earth. With this, he called the force that acted upon things such as that “gravity” and determined that is was applied to all objects in the universe. This part of his theory still stands as we know, because in all the far reaches of the universe, not object is not affected by gravity, be it a weak or strong force. His findings finally approved the studies of Galileo, Brahe, and Kepler. Albert Einstein later developed his new theory on relativity and later the general theory of relativity in 1915, which explain several different discrepancies and phenomena in Newton’s theories.
