This year’s AP Physics B capstones were as great as last year’s. Click there to read more about how I structure capstones.

- Joe’s GravitON â€“ A Python based N-Body Gravity Simulator. Cleanly implemented and well documented VPython implementation of the n-body problem. Can’t wait until Joe offloads process to the GPU!
- Danny’s Resistance Bands vs Free Weights. A well-designed experiment to model resistance bands.
- Andrew’s Amateur Kitchen Rocketry. Very creative. Have you ever considered building an olive-oil-powered rocket?
- Helen’s [Springboard Diving](Amateur Kitchen Rocketry). Great video analysis and fantastic video interviews of coaches and divers.
- Matt’s Pony Physics: Very creative and thorough exploration of the physics of My Little Pony.
- Andrew’s Rifle Toss: wonderful application of more advanced physics to determine the energy needed for an 8-rotation rifle toss. (Web page struggles to display the equations; refer to PDF at the bottom.)
- Nathan’s Physics of Intonation: answers the question “how important is it to play in tune?” Includes a Python script that calculates superposition and a great Minute Physics-style video.
- Nathan’s Putt Simulator: Models the motion of a golf ball on a generated surface. Incredible application of calculus and computational modeling. (Requires Python, VPython, and Matplotlib.)
- Michael’s Tunnel to the Center of the Earth: Wonderful Minute Physics-style video supported by Excel-based computational models. Cites Rhett Allain’s How Long Would It Take to Fall through the Earth, solves Rhett’s homework, and then assigns his own.

Based on feedback from students, I’m going to make a one change for next year. Several students actively peer reviewed each other’s capstones. This was fantastic and improved the quality. I wanted to make this a required activity next year.

I think this year’s class benefited from seeing examples from last year’s class. Now that I have a diverse collection of excellent capstones to share, students have an easier time understanding what a capstone is and how to present it in an engaging manner.
