  1. Sneaker Lab

  2. Write Up • Problem • Hypothesis • Variables • Materials • Procedure • Data • Results • Conclusion • Page 338

  3. Problem • How does the amount of friction between a sneaker and a surface compare for different brands of sneakers?

  4. Hypothisis • Which sneaker/ shoe has the most fiction, least friction?

  5. Variables • List all variables in this lab • Control Variables • Dependent/ Responding Variable • Independent/ Manipulated Variable • I will not give them to you.

  6. Materials • Shoes • Spring scales • Tape • Paper Clips • Balance

  7. Procedure • Record the mass of each sneaker on a balance • Equal out the masses for each sneaker to 1000g • Spread out the masses evenly throughout the shoe • Tape a paper clip to each sneaker • Attach a spring scale to each paper clip • Measure starting friction (pull from a stop position) • Forward stopping friction (at a slow constant pull) • Sideways friction (at a slow constant pull) • Read paage 338 so you know where to tape the shoe

  8. Data Table

  9. Results • Rank the friction forces from least to greatest.

  10. Conclusion • Why is the reading on the spring scale equal to the friction force in each case? • Which shoe had the most friction, which had the least for all three types? • Do you think using a shoe with a small amount of mass is a fair test? Why or why not? • Is there a relationship between friction and brand of shoe? What is it? • Why do some shoes grip the floor better than others?
