How to Determine the Coefficient of Static and Kinetic Friction

Tools Needed for the Activity

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 coefficientof static friction between your object and the surface. Show all calculations. Include aclearly labelled free-body diagram.3. Now, using the same tools, figure out a procedure to determine the coefficient ofkinetic friction. State your procedure. If you are having trouble with this, you may ask forhints from the teacher!4. Perform your procedure to take the measurement(s) required. Calculate thecoefficient 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 howyou can prove that mass is/is not necessary...a) mathematically andb) experimentally.

6. What are some possible sources of error in your investigation? How did you (or couldyou) reduce the error?7. What safety measures did you need to follow to carry out this investigation?Not mandatory Extension: Friction is very often thought of as a disadvantage because it“resists” motion. However, it has its advantages. Explain one advantage and onedisadvantage for each of static and kinetic friction. Aim to give unique and interestingexamples
