hi, i know i posted this question in response to your retarding forces video (
), but per your advice i created an account here.
anyway, do you think it is advisable just to memorize the equation you derived? or will the AP Phys. C test make you figure it out on your own? will i just need to plug in numbers? (In other words, what stuff from the video do I actually need to keep in my head? how will i use it?)
sorry for so many questions; an answer such as "know how to derive them" or "you don't need to memorize any of it" or "just plug in numbers" will do!
