Working with a model of a ladder, students determine the coefficient of friction necessary to keep the ladder in static equilibrium.
- Variable Mass System
- College Board AP Curriculum-Aligned Labs
- Hinged Board and Friction Board Included
- Material and Instructions for Six Students per Lab Group
- Ideal for AP I and II, IB, and Advanced Honors Physics Courses
Various hooks allow users to place a mass at different positions, so the center of mass of the system can be varied. A hinged block on the bottom of the ladder ensures the contact surface is always maintained.
The lab is aligned with the College Board AP Curriculum. It includes instructions and materials for up to six students per lab group. The lab is ideal for AP I and II courses, IB courses, and advanced honors physics courses and is aligned with the College Board AP Curriculum.
