How to Prepare for the F=ma Physics Contest

What is the F=ma Contest

 

The F=ma is a physics contest organized by the Association of Physics Teachers (AAPT). The F=ma exam consists of 25 multiple-choice questions related to classical mechanics, and tests skills on how to apply fundamental principles to real-world scenarios. There is no negative marking, so remember to put an answer for every question. 

The top 400 students approximately on the F=ma are invited to take the USA Physics Olympiad (USAPhO). The cut-off is usually between 14-18 for the USAPhO.

There are two exams "F=ma A" and "F=ma B". Students may take both F=ma A & B exams, but they must meet or exceed the cutoff score for both exams to move on to the USAPhO exam. There is no benefit for students to take both exams.

They exams are typically held in February 2023. The problems can be solved without the use of calculus, although knowing basic calculus can help you find quicker solution for some problems.

Who can take the F=ma

 

Students taking the F=ma exam must be either U.S. Citizens, U.S. Permanent Residents (Green Card holders), or currently attending a U.S. school.

 

Where can you take the F=ma

Both the F=ma and USAPhO exams must be proctored. Parents or relatives of students are not acceptable proctors. It is expected that competitors will take the exam at their local school, though they may take the exam elsewhere if needed.
Homeschooled students should contact nearby high schools, community colleges, or universities to ask if they can take the exam there. Parents or relatives of homeschooled students are not acceptable proctors.

How to score high on the F=ma

 

So, how can you score well on the F=ma? Here are four key things to focus on:

 

  1. Understanding all the content: The exams asks questions only on mechanics, so you need to understand all the topics in mechanics and learn how to apply them to complex scenarios.

  2. Solving the problems accurately: You need to simulate test conditions to learn how to avoid common mistakes like calculation errors, silly mistakes, misreading the questions, etc 

  3. Working quickly: You need to finish 25 problems in 75 minutes, and you need to learn good time management so you can attempt most of the questions without getting stuck.

12. Introduction to Classical Mechanics: With Problems and Solutions by David Morin  

This textbook covers all the standard introductory topics in classical mechanics, including Newton's laws, oscillations, energy, momentum, angular momentum, planetary motion, and special relativity. It also explores more advanced topics, such as normal modes, the Lagrangian method, gyroscopic motion, fictitious forces, 4-vectors, and general relativity.

13. Problems and Solutions in Introductory Mechanics by David Morin  

This problem book is ideal for high-school and college students in search of practice problems with detailed solutions. All of the standard introductory topics in mechanics are covered: kinematics, Newton’s laws, energy, momentum, angular momentum, oscillations, gravity, and fictitious forces.The introduction to each chapter provides an overview of the relevant concepts. Students can then warm up with a series of multiple-choice questions before diving into the free-response problems which constitute the bulk of the book.
