Name: 8 General Suggestions for the Free Response Questions of any AP Physics Exam Category: Exam Prep Date Added: 08 May 2014 - 09:21 AM Submitter: Flipping Physics Short Description: 8 General Suggestions for the Free Response Questions of any AP Physics Exam After 11 years of teaching AP Physics, going through countless old exams and grading an equally innumerable number of student solutions to Free Response Questions, here are my suggestions to help future students out.

AP® is a registered trademark of the College Board, which was not involved in the production of, and does not endorse, this product. General Suggestion #9: Read Carefully. I made the video you are currently watching and then I proceeded to make video solutions to the 3 Free Response Questions of the 1998 AP Physics C Mechanics Exam and I learned a valuable lesson. I should have given 9 suggestions. I should have added a 9th suggestion: "Read Carefully." I find it quite funny that I didn't read carefully enough because (1) for years it is something I berated my students about and (2) it is something I did not do on the third free response question. You see, I didn't answer part (a) completely. I missed the small word "magnitude". I simply drew the forces in the Free Body Diagrams, however, I didn't explicitly solve for the Magnitudes of the Forces. All the magnitudes of the forces are in my solutions because I had to find each one to solve the rest of the problem; however, I didn't quite answer part (a) correctly. I don't know how the AP graders would grade my solution because all the physics is there, just not in the right places; however, I do feel they would not have given my solution full credit. So, please learn from my mistake and read the questions carefully. Don't have to eat humble pie, like me. View Video

As late as it might be, I'd just like to take a bit to reflect on the ap exams. We worked our butts off to try and achieve the highest possible. I bough review books, took old practice exams, and worked out all part 2 problems from recent years. Needless to say, i was completely prepared by may to take that test. And yet, I still walked into that exam and came out a little uneasy. The mechanics exam was relatively straightfo​rward, with just one part two that gave me grief. However, mr. Fullerton put it best: "electrici​ty and magnetism was a bear". I hope I'm not the only one feeling this way.

Have you ever wondered how compasses work? How they always point the same direction? It's because the Earth is just a big magnet! Compasses are magnetized so they always point north, no matter where you are on the Earth. But why does this happen? That is because the north side of the compass is attracted to the geographic North pole. This shouldn't make sense because opposites attract, so two north poles of a magnet should repel each other. This can be easily explained- the "North Pole" is really the magnetic south pole of the Earth. So when a compass is pointing north, it is really pointing to the south end of the Earth. However, compasses can be easily interfered with. They're just sensitive magnets, so if another magnet comes close to the compass, it will point towards the south end of the other magnet, and no longer point to the Earth's North Pole!
