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 sloped Questions: 1. State the tools you will use to perform the inquiry activity. 2. Determine the coefficient of static friction between your object and the surface. Show all calculations. Include a clearly labelled free-body diagram. 3. 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? 4. What are some sources of error in your investigation? How did you (or could you) reduce the error? 5. Extension: Friction is very often thought of as a disadvantage because it "resists" motion. However, it has its advantages. Explain one advantage and one disadvantage for each of static and kinetic friction. Aim to give unique and interesting examples
