CHAPTER 6

Memorizing Equations in the Shower

IN THIS CHAPTER
Summary: Learn how to memorize all the equations you absolutely need to know to ace the AP Physics exam.

Key Ideas
Learn why memorizing equations is so critical.
Learn equations by using them: practice solving problems without looking up the equations you need.
Use mnemonic devices to help you remember.
Practice speed: see how many equations you can say in four minutes.
Use visual reminders: put a copy of the equation sheet somewhere you’ll see it often.
