Facts about the test: The AP Physics 1 exam has 50 multiple-choice questions (45 single-select and 5 multiple-select) and you will be given 90 minutes to complete the section. That means it should take you around 15 minutes to complete 8 questions.
The following questions were not written by College Board and, although they cover information outlined in the AP Physics 1 Course and Exam Description, the formatting of the exam may be different and difficulty may vary. The questions below cover:
Free-Body Diagrams
Contact Forces
Newton's First Law
Newton's Second Law
Newton's Third Law
