Welcome to the registration for the F=ma Exam!!

  • The F=ma Exam is the preliminary exam for the U.S. Physics Team. Students registering to take the F=ma exam must be U.S. Citizens or legal permanent residents of the United States (green card holders).
  • Two versions of F=ma exam will be given on two different dates (F=ma A, January 23rd, and F=ma B, January 28th) in order to accommodate a larger number of participants.
  • The F=ma exam focuses on mechanics, including kinematics, statics, Newton’s laws, momentum and energy, oscillations, orbital mechanics, fluids, and elementary data analysis. All problems can be solved without the use of calculus.
  • The F=ma A and F=ma B are designed to cover the same topics and have the same difficulty, but will have completely different questions.
  • It is expected that students will take only one of the F=ma exams, but they may take both exams if they wish. If students wish to take both F=ma exams, you will need to select, and pay for both dates during registration.
  • We will select approximately 400 students from the F=ma exams to move on to the USAPhO exam. The two F=ma exams will have different cutoffs for USAPhO qualification, adjusted for the difficulty of each exam. Students who take both F=ma exams will qualify for USAPhO if either of their F=ma results meet the respective cutoff.
