Coefficient of Friction Lab Questions

The video tutorial guides physics students through a lab experiment to measure the coefficient of friction. It begins with an introduction to the lab setup, followed by detailed instructions on measuring normal force using a spring scale. The tutorial then demonstrates how to measure friction force on various surfaces, including a shoe, a block, and a block with sandpaper. The video concludes with a review of the collected data and instructions for completing the lab write-up.

What is the main purpose of the coefficient of friction lab?
