Use the links within the site to find additional information to answer the questions. http://www.ducksters.com/biography/scientists/isaac_newton.php 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. What were Newton’s three jobs? Mathematician Physicist Astronomer How many years did Newton live? 84 years What are the 2 main things that Newton is known for? Discovering Gravity Invented a new type of mathematics, Calculus Google searche “universal gravity” and define it. every object in the universe attracts every other object What is “physics”? Is a branch of science that studies matter and its motion as well as how it interacts with energy and forces What are the scientists that study physics called? physicist Who raised Newton for most of his life? After his mom remarried, she left young Isaac to live with his grandparents. What type of student was Isaac? an adequate student Define “adequate”. satisfactory or acceptable in quality or quantity. Why did Newton spend 2 years in isolation? Great Plague, so he stayed in his home and started developing his theories on calculus, gravity, and the laws of motion. What is the name of one of the most “important works in the history of science” that was completed by Newton? Philosophiae Naturalis Principia Mathematica What is “force”? 11. 12. - 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. is any interaction that, when unopposed, will change the motion of an object What two things do we use to describe force? A push or pull. What is the 1st Law of motion? An object in motion stays in motion and an object at rest stays at rest unless acted on by an unbalanced force. Provide an example. When a car stops quickly, everything in the car flies forward. What is the 2nd Law of Motion? F =mass x acceleration Provide an example. An object with a greater mass accelerates less than an object with less mass. What is the 3rd Law of Motion? for every action there is an equal and opposite reaction Provide an example. Action - A book pushes down on a desk. Reaction - Desk pushes up on the book. What kind of force keeps in your seat when you go arund a loop on a roller coaster? centripetal force What two things affect the amount of gravity? Mass and distance Who made some improvements on Newton’s theories on Gravity? Galileo Galilei How much would a 120 pound person weigh on Mars? 47 lbs. If you dived off a plane, what would be your terminal velocity? 240–290 km/h (around 150–180 mph) If Newton was in charge of the math department, what would he call Calculus class? fluxions What is astronomy? the branch of science which deals with celestial objects, space, and the physical universe as a whole. How are Reflecting Telescopes different from other telescopes? They use mirrors to gather light while other telescopes for example, refracting telescopes use lenses. Why would observatories be built on mountain tops? is to get away from the distortion of starlight due to the atmosphere,and to get above the cloud level. What state has the world’s largest refracting telescope!? Wisconsin What do you think Isaac Newton meant by ths quote? “If I have seen further than others, it is by standing upon the shoulders of giants.” - I believe Newton meant by this quote is using the understanding gained by major thinkers who have gone before, in order to make intellectual progress.
