Omega LearnHow to Prepare for the F=ma Physics Contest
HighWhat is the F=ma exam?
The F=ma exam is a 25-question, 75-minute multiple choice competition covering classical mechanics, organized by the American Association of Physics Teachers (AAPT). The top 400 scorers advance to the USA Physics Olympiad (USAPhO).
Format
25 multiple-choice questions in 75 minutes, all on classical mechanics. Calculus helps but is not required.
Who can enter
Eligible students must be U.S. citizens, permanent residents, or attend a U.S. school. Homeschooled students must arrange testing at a nearby educational institution.
When & how
Held in February and must be proctored. Parents and relatives cannot proctor the exam.
How to advance
The top 400 scorers move on to the USAPhO; typically you need 14โ18 correct to advance.
Scoring Strategy
To do well on the F=ma exam, focus on these four key areas:
Understand all content
Master every topic in classical mechanics: kinematics, Newton's laws, energy, momentum, rotation, oscillations, and waves.
Solve accurately
There is no penalty for wrong answers, so careful and accurate problem solving is essential to maximize your score.
Work quickly
With only 3 minutes per problem on average, practice solving problems efficiently. Skip hard questions and return to them.
Manage your time
Attempt all 25 problems and leave no question blank. Budget time for review at the end.
