Students determine the coefficient of friction of a block of wood using three different methods: dragging the block with a force meter, sliding a block down an incline, and pulling a block across a horizontal surface.
- Measure Three Methods of Friction
- College Board AP Curriculum-Aligned Labs
- AP Physics Teacher Wrote Teacher Guides and Student Manuals
- Material and Instructions for Six Students per Lab Group
- Ideal for AP I and II, IB, and Advanced Honors Physics Courses
In each method, the free-body diagram helps students identify the forces acting upon the block and leads them into investigating frictional force effects on an accelerating object. The lab is ideal for AP I and II courses, IB courses, and advanced physics courses.

Accessories information: AP Physics instructors authored the teacher's guides and student manuals, which are available separately.
Ordering information: The kit includes a friction block with a hook, 20 N and 10 N spring scales, inclined plane with pulley, stopwatch, tape, string, and protractor. A triple beam balance and masses are required but not included.
