Help make this better.
This site exists to help students actually understand AP Physics 1. If something is unclear, if a solution is wrong, if an explanation didn't land, or if there's a topic you wish was covered differently, tell me. Every piece of feedback shapes the next revision.
What's on your mind?
Fill out whatever feels relevant. Nothing is required except the message itself. No account, no sign-up. Takes under a minute.
The most useful kinds of feedback
Errors and corrections
If you find a wrong answer, a typo, a formula that doesn't match the one in your textbook, or an explanation that contradicts itself, please flag it. This is the single most valuable kind of feedback. I update the site directly within a few days of hearing about errors.
Things that didn't click
If a lesson went too fast, skipped a step, or used an analogy that didn't make sense, tell me which unit and which part. "The energy transfer explanation in Unit 3 lost me around the second worked example" is enough for me to go back and rework it.
Topics you wish were covered differently
If your class approaches a topic in a way the site doesn't, or if there's a type of problem you wanted more of, let me know. The site should serve how students actually need to study, not just how I thought about it when I built it.
What's working
Honestly, hearing that something helped is useful too. It tells me which parts to keep expanding and which style of explanation to use more of.
