Physics Aviary: Moment of Inertia of Pulley
This lab is designed to have students learn how the size, mass and mass distribution of a pulley influences the rate at which a mass attached to the pulley will accelerate. The pulley is frictionless and the string's mass is negligible.
Physics Aviary
Physics Aviary: Pulley Lab
This lab is designed to have students find the relationship between the number of pulleys used and the force required to lift a mass. Students will see that it is not actually the number of pulleys that matter, but the number of strings...
