SAT / ACT Prep Online Guides and Tips

Both of the AP Physics C exams supply a nifty information sheet with the exam booklet on test day. This information sheet is packed full of formulas and equations that are used in physics, which means it can be extremely useful as you prepare for and take the AP Physics C exams.

There's a lot of information on the three page equations sheet provided on the AP Physics C exams, though, so it's important to be familiar with the info included on the sheet and how to use it to your advantage during the AP exams.

That's why we've developed the PrepScholar AP Physics C equation sheet. Our sheet contains all the formulas and information you'll see on the official College Board Physics C equation sheet, plus explanations of the equations so you'll know when to use them. This sheet is designed to be a study tool for you as you prepare for your AP Physics C exam.

To further help you learn the ins and outs of the AP Physics C reference tables, we'll also do the following in this article:

• Explain how to use the AP Physics C equation sheet, section by section
• Provide three tips for using the equations sheet to prepare for the AP Physics C exams
• Provide three tips for using the equations sheet during the actual AP exams.
