# Unit 4: The Metric System & Linear Motion

Due Date: 4/17/06

## Linear Motion

Objectives: At the end of this unit you will be able to:

1. Build an understanding of linear motion.
2. Define and calculate the speed and acceleration of various objects.
3. Differentiate between instantaneous speed and average speed.
4. Calculate the velocity and the displacement of an object undergoing constant acceleration.
5. Analyze acceleration as rate of change in velocity.

Required Assignments. (This means you MUST do them.)

_____ 1. Compete in “The Metric Olympics”.

_____ 2. Speed Lab

_____ 3. Graphs

_____ 4. Acceleration Lab

Required notes for this section. (Again … this means you MUST do them.)

_____ 1. The Metric System

_____ 2. Speed (Average vs. Instantaneous)

_____ 3. Acceleration

_____ 4. Graphs of motion

______ “C Level”. (Here is where you get to choose what you want to do.)

30 points are necessary for a C.

_____1. Read pages 48 – 49 in your book.  Complete the miniLab on page (10 points)

_____ 2. By any method you choose, determine your average speed of walking. (5 points)

_____ 3. Read pages 63 – 69 in your book.  Answer questions 1-3 on page 69.  Be able to answer questions.  (5 points)

_____ 4. Read pages 72 – 75 in your book.  Answer question 1-3 on page 75.  Be able to answer questions.  (5 points)

_____ 5. Complete the worksheet entitled, “Running a yellow light.” Be able to answer questions. (5 points)

_____ 6. Create an accelerometer.  Refer to the handout for directions. (5 points)

_____ 7. Complete the handout entitled, “Physics skills – graphing techniques.” Be able to answer questions. (5 points)

_____ 8. Complete the lab entitled, “Pocket lab – Uniform or Not?” Do both sides.  Be able to answer questions. (5 points)

_____ 10. Complete questions 23 and 24 on page 91 of your book. (5 points)

_____ 11. Complete the handout entitled, “Critical thinking – Acceleration and escape velocity.” Be able to answer questions. (5 points)

_____ 12. Complete the miniLab worksheet entitled, “How can you describe the motion of a car?” Be able to answer questions. (5 points)

_____ 13. If you’re interested in the luge, go to the following site:                            http://btc.montana.edu/olympics/physbio/physics/phys-intro.html                         Complete the linear kinematics (introduction, getting started, and kinematics: fundamental concepts and activities section).                                                             You will learn the physics of the luge.  This is a VERY cool site!                               (20 points)

_____ 14. If you’re interested in hockey, go to the following site:                     http://www.exploratorium.edu/hockey/index.html                                                     Read through the various links.  Have fun!  Be able to answer a question or two.  Again, a VERY cool site! (10 points)

_____ 17. If you’re having a hard time and need more written-type data (like the book) then go to the following site:    http://www.dl.ket.org/physics/companion/thepc/home/mech.htm                          Check out their graphing skills section, kinematics (velocity) section, and/or their kinematics (acceleration) section.  You’ll get 5 points per section here.  It’s very reader friendly – great if you just need another source!

_____ 18. With a group of 2 to 4 students, design and perform a skit that “teaches” the difference between speed, velocity and acceleration. (15 points)

_____ 19. Compose a song that “teaches” the difference between speed, velocity and acceleration. (10 points)

_____ 20. Look up the Olympic records for the 100-m dash and the 100-m freestyle for men and women. Calculate the average speeds of the record holders and compare them. (10 points)

_____ 21. Make and solve 5 problems involving speed, velocity, and acceleration. You must include at least 1 problem from each term. (10 points)

____________  “B” Level: Choose ONE only.

____ 1. Interview a police officer about how a radar gun is able to track how fast a person is driving. Submit your "typed" interview (your questions and the police officer's answers)

____ 2. Visit a stream and determine the velocity of the water over a given distance.

____ 3.  Compare the acceleration of 3 different objects. Graph your results

____________ “A” Level: Choose ONE only.

____ 1. Go back and research the history of linear motion.  Name the big names and describe their contribution (you can start with Aristotle).

____ 2. Design a powerpoint or some other presentation that demonstrates how this Unit relates to a topic of your choice (not luge or hockey obviously).
