* The terms and concepts above have directly come up on past IB Physics exams from May 2016 onwards.
Directly in this context means that the answer to a Paper 1 or Paper 2 question was the definition of the term or concept or that the answer could be deduced directly from the definition. Therefore, this list might be helpful when you are deciding what to memorize for your IB Physics exams.
