  1. Complete the following questions, using your background reading and your notes. Answer in complete sentences. Due Wednesday, March 5th. 

    1)  Explain two ways a heavy truck and a person on a skateboard can have the same momentum.

  2. 2)  In stopping an object, how does the time of impact effect the magnitude of the force used to stop the object?

  3. 3)  What is the relationship between an impulse on an object and the change in momentum of that object?

  4. 4)  For a constant force, if the time the force is applied to an object doubles, the impulse will __________.

  5. 5)  From question #4, by how much is the object’s momentum changed?

  6. 6)  In a car crash, what is the advantage of an air bag in terms of impulse/change in momentum?

  7. 7)  Why is the impulse greater on a falling object that bounces instead of an equally massive object that doesn’t bounce?

  8. 8)  Explain why a tossed egg can be caught with a sagging sheet but not a piece of plywood?

  9. 9)  A bug and the windshield of a moving car collide. Indicate which of the following statements are TRUE.

    a. The impact force on the bug and the car are the same magnitude.
    b. The impulse on the bug and the car are the same magnitude.
    c. The change in momentum of the bug and the car are the same magnitude. d. The change in velocity of the bug and the car are the same.

STUDY!

Metric-to-Metric Conversions + Syllabus Quiz TOMORROW! 

On the quiz, students will need to perform the following skills, as discussed in class: 
  • Relate base units with the quantities they measure (i.e. the meter is the base unit of length, and is symbolized by an "m")
  • Identify numerical prefixes
  • Relate numerical prefixes to quantities such as hundreds, thousands, etc. 
  • Perform metric to metric conversions. 
You will need to know where the prefixes fall in your metric line...this will not be provided for you on the quiz!
 
There will also be four questions concerning policies on my syllabus...make sure you familiarize yourself with the document tonight! A copy is available for download on my home page should you need it!
 
Tutoring: I will be in my classroom tomorrow morning and available for tutoring starting @ 7:25***...come see me if you have any questions/concerns! Let's start this year off strong!

***Update: Due to teaching my zero hour PE class, I will be available for tutoring from about 7:40 to 7:55. Please feel free to go over material if you need to!
