High schoolers investigate a pulley system in the lab. For this pulley system lesson plan, students build a pulley system using weights, strings and wheels. They calculate the work output, work input and efficiency of the system. They also find the ideal mechanical advantage and the actual mechanical advantage of the system. High schoolers answer 6 post lab questions about the system they built and how friction effects the work.
