Question

1. Which material exhibited the smallest coefficient of static friction? How does this relate to the surface material? Does the same material have the smallest coefficient of kinetic friction?

2. Compare the fractional uncertainties of all the coefficients. Which coefficient showed to have the least amount of uncertainty compared to the others? Why do you think this is so?

3. What are the sources of uncertainty associated with this experiment? State whether they are a random uncertainty, or a systematic uncertainty.

4. The Coefficient of Static Friction for wood on wood is from 0.25 to 0.5, and the Coefficient for Kinetic Friction for wood on wood is approximately 0.2. How well do your values compare with these?

5. If this experiment used an incline plane to pull the wooden block up the plane with the force sensor what changes to the formula would you have to consider? Write the new set of formulas.
