Sir Isaac Newton was a very important element when considering modern science. He made many contributions in many fields, mainly physics. In my essay, I will explore some of the ideas that Sir Isaac Newton talked about and studied throughout his life. Say no to plagiarism.

These laws are essentially made up of three parts: The first law states that "any object in a state of uniform motion will remain in that state of motion unless an external force acts on it." This means that if an object is stationary, it will remain stationary unless a force acts on it. This means that if you hit a ball, it will fly forever unless another force acts on it, which it does (air resistance and gravity). The second law of gravity is simply that force is equal to mass times acceleration, which can be written as f=ma. This means that as the mass decreases, the acceleration must increase. The third law states that “every action has an equal and opposite reaction.” This law says that for example, if you kick a ball, the ball also pushes back towards you. Second, I write about one of Newton's lesser-known areas of study, optics. It was he who first discovered the rainbow and its main colors (red, orange, yellow, green, blue and violet). He experimented with a prism and wrote many journals and books on this field. In Newton's time, many people believed that color was a mixture of dark and light and that prisms colored light. Newton knew that this theory was not true. He used refraction to prove that all colors come from pure white light. Artists were fascinated by Newton's discoveries, which led to another of his inventions, which was an original version of a color wheel that was later adapted and modified by Claude Boutet. This discovery is almost overshadowed by Newton's more "important" discoveries such as his universal laws of gravity. Newton's law of universal gravity can be commonly known as F=Gm1m2/r2. This generally means that each particle attracts all other particles with a force directly proportional to their mass. This means that everything in this universe is attracted to each other, regardless of the size of the mass of the objects. The equation written above is correct but is not written in the correct direction because I am not able to type some parts of the equation. Sir Isaac Newton was also one of the first scientists to suggest that the Earth was not in fact completely spherical but rather was an oblate spheroid, which is a sphere but whose poles are crushed and the equator is “inflated”. This "bulge" can be proven since the distance between the center of the Earth and the equator is 21 kilometers, which is a greater distance than the distance between the center of the Earth and one of the poles. In fact, we recently discovered that the Earth also has a certain plasticity that allows it to deform slightly, almost like silly putty, but much less pliable. Newton also made some discoveries regarding calculus (Isaac Newton Algebra) and also made a lot of progress in the speed of sound and introduced the concept of Newtonian fluid. In addition to his discoveries..
