Project #2  - Newton’s Car Due on 10/9/13  pg 317-324  How to build: http://www.youtube.com/watch?v=v3pbVAYkGf0

Responsibilities:

To all my DAM Scientists:

Welcome to our second competition, Project 2 Newton's Car. I hope you enjoyed the competition in Project 1. Using the knowledge and experience that you have gained from our first competition, Soap-box Derby, we will continue with this process in Project 2. In Project 2 you will learn and understand the concept of friction. You are required to build a car powered by elastic force. You need to test and determine the performance of this car on two different surfaces. The two surfaces are represented by dry and wet road conditions. As usual, be prepared and start early. If you have any question pleased proceed to DAM Headquarter in room 374 before, during and after work(school). As usual, the losing team will have to clean. Good luck on competition date October 9, 2013.

 

I. Objective: To design and build a car powered by rubber bands that can achieve the highest average speed in two different surfaces.

 

II. Research: Which surface is better, smooth or rough? (about 50 words)

 

III. Hypothesis:        Which surface is better? Why?

 

 IV. Materials:

  1. CD’s                       
  2. Card board boxes
  3. Round wood or metal rods
  4. Glue or tape
  5. Rubber bands
  6. Ruler
  7. Bottle caps

 

V. Requirements:

  1. The length of your car must be at least 10 inches.
  2. The width of your car must be at least 3 inches and maximum 10 inches.

 

VI. Grading:

  1. To get an A your car must travel more than two meters
  2. To get a B your car travels less than 2 meters
  3. To get a C your car doesn't work

 

VII. Procedure: How did you build your project?(Must have at least 5 steps, hint: look at Project 1 Procedure)

     10.

 

VIII. Data Table: create two tables of 4 columns and 6 rows

IX. Graphing: Create a Position vs Time graph for both surfaces

X. Results (What went right, what went wrong?)

XI. Conclusion (3 paragraphs)

 

XII. How did you feel about this project?

 

XIII. What concepts in science have you learned? (use scientific terms to answer this question)
 

                           Answer the following question:

            A. What is the displacement?

            B. What is the total distance traveled?

            C. What is the total time traveled?

            D. What is the average speed?

            E. Is your displacement the same as your distance? If No, why not?

            F. What is friction?

            G. What is the unit for friction?

            H. What does friction depend on?
