Hey everyone hows it going? I am not sure if this is the right place to be posting this question, but hopefully it is. My names Shawn and I am a senior in high school. I currently have AP calculus and gen physics, and I plan on taking the AP calculus test (ab) and hopefully the physics AP test, but I am not sure which one to take? Has anyone here taken either? I have borrowed an AP physics book ( Princeton review) and have been teaching it to myself. I think I am getting the concepts and everything but get lost a little here and there. Right now I am reading about Rotational Motion, but I am lost on drawing a Free body diagram. I can draw them right most of the time, but when it comes to putting it into the equation Fnet=ma thats where i get lost..So what should i be asking myself before i attempt to put it into the equation?. So any help on that would be greatly appreciated! Also i am having a tough time on the free response questions after every chapter, i can do the multiple choice questions with a little effort,but get stumped at the free response. After I see it done i always say "oh why didn't i think of that?". I am just having a hard time plugging equations into other equations into other equations etc to find what i need. Also one last thing, i learn best by doing problems so if you know of any good sites with problems AND ANSWERS with it worked out that would be awesome! Thanks for taking the time to help me!(adsbygoogle = window.adsbygoogle || []).push({});
