T-bird Physics Test: Newton

Please take this quiz to show how much you have learned in this unit. Please note: each multiple choice question is followed by a question asking you to explain your answer to the previous question. You must explain how you arrived at your answer; tell me what you know and how you figured out the answer and then I will understand better what you know and can do.


Questions and Answers
  • 1. 
    Explain your thinking in question #1. Showing your work or setting up the problem will be fine.
  • 2. 
    Explain your thinking in question #3. Show your work or explain how you see the relationship between force, mass, and acceleration.
  • 3. 
    Explain your thinking in question #5. Show your work or explain how you see the relationship between force, mass, and acceleration.
  • 4. 
    Explain your thinking in question #7. Show your work or explain how you see the relationship between force, mass, and acceleration.
  • 5. 
    Explain why your answer to #9 is correct:
  • 6. 
    Look at the diagram below of an arrow being shot horizontally from a bow and another being dropped from the same height. Arrow A is shot horizontally at 50 m/s. Arrow B is dropped at the exact same instant that Arrow A leaves the bow. Neglecting air resistance, how does the time Arrow A takes to hit the horizontal plane in the diagram compare with the time Arrow B takes to strike the same horizonatal plane?
  • 7. 
    Use scientific language and your understanding of projectile motion to prove that a 100 mi/h pitch thrown horizontally by a major league player will hit the ground in the same amount of time as a 10 mi/h pitch thrown horizontally from the same height by a child.
