Information about how the answer checker works.

If you're a teacher who is interested in seeing how the answer checker works, you might want to try the demonstration first. If you're a physics teacher and want to see how it works on some physics examples, you could also download one of my free books, pick a homework problem out of the book, and try entering correct and incorrect answers in Spotter. (The full text of the physics problems is not displayed by Spotter.)
