PHYSICS: Girl on a sled coasts down a hill, box is pushed up a hill… Is it starting to make a little more sense? Here’s our review of problems 40, 52, and 48 (I think).
Here’s the thing. You can watch me or someone else do a thousand problems (okay, maybe not a thousand – but a lot!), and it won’t help. I don’t want you to copy what I do, I want you copy why I’m doing it. Make sense? You’re getting it…keep sledding and watch out for net forces!
