AP Physics I is an introductory, algebra-based Physics course equivalent to a first semester college level course.It is designed to develop advanced inquiry and scientific reasoning skills necessary for designing and planning data collection, analysis, applying mathematical routines, and making connections across concepts. AP Physics I introduces the main principles of physics: Newtonian mechanics; work, energy, and power; mechanical waves and sounds; and introduction to electric circuits.This course is supplemented by selected readings in textbooks and periodicals, and laboratory investigations.
