Newton and his Laws
Isaac Newton was born in the house of Woolsthorpe, near Grantham in Lincolnshire. Isaac Newton was a mathematician and physicist; he was the primary scientific intellect of all time. Newton came from a family of farmers. Isaac was named after his father; however, he never knew his dad because he died three months before he was born. In 1661, Isaac Newton had entered Cambridge University that was his uncle's old college, where he was elected to a Fellow of Trinity College in 1667. After graduating college and becoming a professor, Newton's most success came in his work in physics and celestial mechanics. Newton wrote three books, each book explaining something new and more about his first theory of universal gravitation. Newton had identified gravitation as the fundamental force controlling the motions of the celestial bodies. However, he did not found its cause yet when he wrote the Principia. In 1666, Newton had a vision of his three laws of motion that he had come up with. Newton's First Law is, in laymen terms: " An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force". This law is br
The seat belt is used to the persons motion forward as the equal and opposite reaction. This third law helped advanced safety for cars, by understanding the third law scientists started to realize that a car need a safety belt. There are two categories that deal with force, one is contact force and the other is force resulting from action-at-a-distance. This law has to do mostly with regulating all acceleration on forces. When the vehicle comes to a halt, the car had an outside force to stop it the people in the car keep moving at the same speed before the car was stopped. This third law by Newton appears easy to see, however it is extremely important law to understand. Unlike Newton's first law, the second is more theoretical. People know this law by commonsense the heavier the object the more force required to move it a certain distance, rather if the object was lighter less force is required to movie the object the same distance. This law and the first law allow space travel in outer space. If a person puts a force on any object, it will accelerate in the same direction. The last part about of Newton's second law was the inversely proportional to the mass of the object. Acceleration is equal to the rate at which speed changes. The inverse proportion means that when X is multiplied by k, Y gets the inverse and gets divided by k. This act of force brings Newton's to his second law of motion.
