I made these pretty equation sheets for my AP Physics 1 students, using the official AP Physics 1 equation sheets. At the beginning of each unit, we start with these sheets and dissect each equation and right out what I call "secrets" (hints to help with each equation, how they are related, etc). I made a big blown up copy to hand in the room as we go through each unit and they stay up until the AP test.
These are the kinematic equations- students have a LOT of trouble with them but having this sheet handy helps! This could also be a great page in an Interactive Notebook.
