Name:_______________________________ Web Quest – Newton’s Laws of Motion 40 points Directions: Google “Bumpus Middle School”. Go to “Faculty and Staff” and click on my name to access my Wiki Click on the folder on the left hand navigation bar titled, “Webquests”. Then click on “Newton’s webquest” Do the Webquest by following the directions and clicking on the links that will take you to different websites. Follow the directions and write your answers on this answer sheet BALANCED AND UNBALANCED FORCES Force is measured in units known as Newtons (Named for Sir Isaac Newton) 1. What is the net force when no forces are acting on an object? 2. Draw a diagram showing a force of 5N acting on an object. 3. Draw a diagram showing 2 forces acting on an object, but with a total net force of zero. 4. How do you find the total net force if 2 forces are acting on an object in opposite directions? 5. Draw a diagram showing 2 forces acting on an object in opposite directions with a total net force of 3N to the left. 6. How do you find the total net force if forces act on an object in the same direction? 7. Draw a diagram that shows 2 forces acting on an object in the same direction with a net force of 14N to the right. 8. Write quiz answers here. a. ___________________ d. ___________________ b. ___________________ e. ___________________ c. ___________________ f. ___________________ Sir Isaac Newton 9. When did Isaac Newton live? 10. What was significant about the year he was born? 11. What was his profession? (his job, what he got paid to do) 1 THE LAWS 12. What is Newton’s first law? 13. The website gives both the actual law and also puts the law in simple language. Write what Newton’s first law is in simple language from the website or put it into your own words. 14. What is Newton’s second law? 15. Now write it in simple language. 16. What formula represents Newton’s second law of motion? 17. What is Newton’s third law? 18. Write quiz answers below 1. 5. 2. 6. 3. 7. 4. 8. Go back to the webquest and scroll down to the next set of instructions and the next linkl. READ the webpage before taking the quiz 19. Write quiz answers below 1. 6. 2. 7. 3. 8. 4. 9. 5. 10. EVERY DAY LIFE Give1 example of each of the three laws that happen in your everyday life. 20. Law #1 21. Law #2 22. Law #3 2 Check your understanding of Newton’s Laws of Motion 23. Which has more inertia – a 2,750 gram object or a 2,500 gram object? 24. Newton’s second law states that to increase acceleration, you: a. increase force c. increase mass b. decrease force d. increase inertia 25. An action force and its reaction force are: a. equal in size and direction b. equal in size and opposite in direction c. different in size but in the same direction d. different in size and direction 26. John pulls a box with a force of 4 N, and Jason pulls the same box from the opposite side with a force of 3 N. Ignoring friction, which of the following statements is true? a. the box moves toward John b. the box moves toward Jason 27. c. the box does not move d. there is not enough information to determine if the box moves. Directions: Mark each of the following situations as an example of Newton’s First (1st ), Second (2nd ) or Third (3rd) Law. a. Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction. b. A soccer ball accelerates more than a bowling ball when thrown with the same force. c. A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them. d. A student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up. 28. 6N 1N What is the total net force? (Remember force is a vector quantity so it has size and direction) ________________________________________ 29. 4N What is the total net force? __________________________________________ 2N 3
