The purpose of this inquiry exercise is to determine the coefficients of static and kinetic friction for an object on a surface of your choice.

You will need the following materials:

-a surface that can go from a horizontal position to having a slope (e.g., a cutting board or hard-cover text)

-a measuring tool (protractor or ruler) to figure out angle of incline

-an object of your choice that can slide down the surface you are using once it is slopedGiven the length of cutting board is 0.54m, the time of the mass travel is 0.95s and the mass is 0.3kg

Questions:

1. State the tools you will use to perform the inquiry activity.

2. Use the method that you have used earlier in this activity to determine the coefficient of static friction between your object and the surface. Show all calculations. Include a clearly labelled free-body diagram.

3. Now, using the same tools, figure out a procedure to determine the coefficient of kinetic friction. State your procedure. If you are having trouble with this, you may ask for hints from the teacher!

4. Perform your procedure to take the measurement(s) required. Calculate the coefficient of kinetic friction. Show all calculations. Include a free-body diagram.

5. Was it necessary to know the mass of the object to perform this activity? State how you can prove that mass is/is not necessary mathematically OR experimentally.

6. What are some possible sources of error in your investigation? How did you (or could you) reduce the error?

7. What safety measures did you need to follow to carry out this investigation?
