Best source(s) to get a great grasp on forces/Newton's laws?

[toboldlygo]

So, we're learning about forces and Newton's laws in class, and my professor zips through the material without really explaining anything. I'm having the most trouble understanding f_net=ma (specifically, how that can be used in a free body diagram) and how third-law pairs fit into a free body diagram, and I was wondering what sources you've used to get a better understanding of these things. I'm a very visual/auditory learner, so videos are the best, but any online materials that I can easily access would be great. Any worksheets w/answers and stuff using Newton's laws in calculations would be great, too. Thank you in advance!

I love khan academy, and I went through they're Newton's laws stuff, but it didn't have any examples on more complicated problems, which is what I'm really having trouble with. Thanks, though; I might check them out again.

It would be helpful to know if this is for high school or college, and whether your physics course is algebra or calculus based.

Sorry about that! This is an engineering physics course at college; it's calculus based.

The application of Newton's laws should be well understood while you are in high school! Try University Physics by Freedman, it has very detailed explanation and plenty of exercise.

I didn't actually take physics in high school haha. Thanks for the rec; I'll check it out.
