Isaac Newton was an english mathematician, physicist, and scientist. He discovered gravity, the color spectrum, calculus, and ,his most famous discovery, the three laws of motion. A common belief is that Newton saw an apple fall from a tree while learning about the forces of nature. He realized that some force must have been acting upon it, or else it wouldn’t have moved. Newton called that force gravity and determined that all objects have the force of gravity acting upon it. Gravity is the force that causes a glass to continue falling after falling off a table, or the force that keeps planets in our solar system in line and in the proper position to orbit the sun. The color spectrum was another great discovery by Newton. Newton had an
