Retarding and Drag Forces

[maplepawner 0]

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!

 

thanks again!

Thrilled to help, and welcome to the APlusPhtsics Community!

The short version... The College Board says you need to know how to derive them. Very rarely have they asked students to do so, but it has happened...

Good luck!
