Isaac Newton's discoveries
Newton wrote a book in 1687 which was first written in latin. It was called Principia. One day Newton observed an apple and asked; why did it fall? What ditermined the speed when it falls? he looked at the stars and planets above and wondered how they stayed there. This led him to develop the law of motion which he expressed in his book. -
Description of Newton's Discoveries
In the book Principia Newton mainly talks about his three laws of motion. The first law is inertia. Any object will remain at rest or in motion in a straight line unless forced to change by the application of an external force. The second law is velocity. The velocity of an object can change when an additional force is applied the equation is force=mass X accelaration. The third law is for every acyion or force, there is an equal and opposite reaction. -
Albert Einsteins Impact
Albert Einstein looked at Newton's laws and his impacts. HJe evaluated them and thought about them in different ways. He did not think Newton's ideas about gravity were accurate. So, he decided to build off of the foundation Newton set and change history as we know it today. -
How Newton's laws apply to us today
Newton's laws helped define rules of physics and contributed to the development of many modern technologies. For example, airplanes, rockets and space ships. These have become the main theories studdied in modern day physics. When people in New York City get up and have to go to work, they usually will take the subway system. When they go on most of them don't think about how Newton's laws affect this. When the subway jumps to a hault, the inertia makes your body sway.
