What is Ap physics: Definition and 348 Discussions

In the United States, Advanced Placement (AP) Physics collectively refers to the College Board Advanced Placement Program courses and exams covering various areas of physics. These are intended to be equivalent to university courses that use best practices of physics teaching pedagogy.
Each AP Physics course culminates in an optional exam for which high-performing students may receive some credit towards their college coursework, depending on which college or university they attend.
