Sir isaac newton inventions3/7/2023 The laws of motion were first introduced by Newton in his book called Philosophiae Naturalis Principia Mathematic. Newton expanded on the ideas put forth by Galileo and Descartes. Newton did not come up with these laws of motion just by himself. The simplified version of this phenomenon has been expressed as, “”You cannot touch without being touched.”” He explains the third law of motion with different examples to help you be able to understand. According to a post by Jim Lucas a live science contributor he states a clear example, when you push a cart, the cart pushes back against you when you pull on a rope, the rope pulls back against you and when gravity pulls you down against the ground, the ground pushes up against your feet. The third law of motion states that for every action there is an equal and opposite reaction. Again, this is just a law of motion that Newton stated based on evidence he saw. So, when a roller coaster is pushed down a hill, it goes from no force to a force being pushed on it causing speed and for it to move. The area the roller coaster is moving through is the mass. When a force is pushed on the roller coaster it causes it to move which causes it to pick up speed or accerlate. The roller coaster is the object that will be accerelting. So, looking back at the roller coaster example will help to explain this law. Accerlation is the increase in the rate or speed of an object. Mass is a body of matter that has no definite shape. ![]() The second law of motion states that force equals mass times accerlation. He did not create anything with this law of motion he just made a statement that is proven true that we still us today in science. As the reader knows this still applies to us today in the twenty first century. If the roller coaster did not have that force, then it would not move. A roller coaster that is sitting still will not go until an object is used to push it to make it go and keep it going. An example of this would be a roller coaster. Motion is a state to which a body is indifferent (Westfall pg.8). The first law of motion says that an external force must be acted upon it to make it stay still or keep moving. Each law of motion has its own set of rules and ways to test them. The third law of motion is When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body. The second law of motion states that force equals mass times acceleration. The first law of motion states that an object will keep moving or stay still until an external force is acted upon it. One thing he discovered was the three basic laws of motion that we still us today in mechanical work. Isaac Newton was famous for a lot of different discoveries that help us still in our lives today. This saying says a lot as to what changes he brings to math and science. He learned a lot at Cambridge but preferred to study more recent information on math and physics than what they were teaching in class based on his saying, Plato is my friend, Aristotle is my friend, but my greatest friend is truth. By his third year at Cambridge, Isaac had started growing an interest in math and what we know today as physics. When Isaac was just eighteen years old he went to Cambridge University Trinity college to study to become a lawyer. Isaac was a very smart boy and he attended a school called The King’s School that had no science or math which is very interesting because of what he contributed to science and math in his later career. This is very eye popping being that he was saying that at a young age and his mother still stayed with his step father. It is often said that Isaac hated his mother and step father so much he wanted to burn their house down. At a very young age, Newton’s mother married a new guy and Isaac hated him, so he lived with his mother’s mother. Isaac is the second Isaac in his family making him a junior and his dad died before he was born. One weird think about his birth date is that some calendars say it is Decemwhile others say that it is January 4, 1643. ![]() Isaac Newton was born January 4 ,1643 in a town called Woolsthorpe which is located in Lincolnshire, England. “Isaac Newton: Inventions that Changed the World”
