How does the Coefficient of Friction depend on the Types of Shoes, which were slid across an ice rink?
1. Chose 5 different types of shoes
2. Find the heaviest shoe and find its mass
3. Put certain amount of masses and other materials into other 4 shoes so that they have the same mass as the heaviest shoe
4. Go to an ice rink
5. Videotape the shoes sliding against the ice
6. Measure the length of the shoes
7. Use Logger Pro to analyze the videos, finding out the velocity and the time
- multiple trials
- keeping mass constant
1. Snow Boots
2. Running Shoes
3. Uggs
4. Flats
5. TOMS
sole materials?
tread patterns?
kind of rubber
