Note: a previous version of this lab used an app called "Hudl Technique" to add a stopwatch feature to the videos so that students could easily time events that happen in the videos. Unfortunately, since that version was uploaded, the app has been acquired by another company and it is no longer free. If you have access to another tool that can time directly and don't need the added stopwatch, the original lab and video can be found here:
TipsNote: these tutorials were recorded for an IB Physics class so the notation might be a little bit different, but the process is still the same Part 2 Part 1: Sliding to a StopThere are several famous video clips online starring people or animals coming to a sliding stop thanks to kinetic friction. Choose one of the videos linked below, open it in YouTube, and make some measurements. Note: there are some useful facts to help you estimate the slide distance in the video. Do your best to incorporate the information that's provided as a reference! Your Task: Determine the coefficient of kinetic friction required to slide to a stop
Part 2: Sticky RampMany phone and tablet cases are rubberized so they don’t slip and slide around very much. In this lab, you will be testing this to the limit by placing your device on an incline until it can no longer hold on. Your Task: Calculate the Coefficient of Static Friction for your phone or iPad
Analysis and Calculations: Before your phone reached the slip angle, it was happily resting in equilibrium with the parallel component of the weight perfectly supported by the force of static friction. Calculate the coefficient of static friction that makes this possible.
