This collection for high school physics integrates lessons, labs, practice problems, assessments, AP review exercises, simulations, and quizzes in one easily-searched location. Initial development began in 1997, with continual updating and expansion occurring since then. Of special note is the section Amusing Problems, consisting of real-life applications designed to make learners think andlaugh. Each problem provides access to solutions for self-evaluation. Course levels addressed in the collection include algebra-based physics, honors physics, and AP physics.
