Review of Mechanical Energy and Momentum Equations and When To Use Them!
Flipping Physics posted a video in Momentum and Collisions
By the time students learn about all the equations for mechanical energy, momentum, impulse and impact force, they often start to confuse the equations with one another. This is a straightforward, simple look at all of those equations and when to use them. This is an AP Physics 1 Topic. Want Lecture Notes? Content Times: 0:14 Tacky Sweater Day! 0:22 Conservation of Mechanical Energy 0:54 Work due to Friction equals Change in Mechanical Energy 1:30 Net Work equals change in Kinetic Energy 3:01 Conservation of Momentum does NOT require the work due to friction to be zero 3:28 The initial and final points when dealing with momentum are predetermined 3:56 Impulse does not equal Impact Force Thank you to Sophie Jones and her family for letting me use six of their sweaters in this video!

8 General Suggestions for the Free Response Questions of any AP Physics Exam
Flipping Physics posted a video in Exam Prep
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. Content Times: 0:21 #1) PreRead All Free Response Questions 0:56 #2) Write Legibly 1:47 #3) Organize Your Solutions and Label All Parts 2:32 #4) SHOW ALL YOUR WORK!! 4:06 #5) Do Not Break Forces in Free Body Diagrams into Components 4:41 #6) Answer Every Part of Every Problem 5:48 #7) Dimension Your Answers 6:11 #8) Leave Algebra Heavy Solutions for Later Next Video: [url="http://www.flippingphysics.com/reviewofallapphysicsctopicsmechanicsvideo1of2.html"]Review of all AP Physics C Mechanics Topics[/url]  Video 1 of 2 All of my inclass [url="http://www.FlippingPhysics.com/calculus.html"]AP Physics C lectures[/url] with Lecture Notes are at: [url="http://www.flippingphysics.com/give.html"]1¢/minute[/url] I know "equally innumerable number" perhaps seems illogical, however, it get's my point across, so deal with it. :) 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. 5 comments

The other night I watched the movie Black Hawk Down, which is based on the book of the same name (written by Mark Bowden) which was based on the actual events of the Battle of Mogadishu. The short story is that the US sent Army Rangers, Delta Force operators and pilots from the 160th Special Operations Aviation Regiment to remove Somalian dictator Mohamed Farrah Aidid from power and in October of 1993 they conducted a raid with the intent of capturing two of Aidid's highest advisers. The operation was supposed to take no longer than an hour and incurr no casualties but after a series of complications it became a full battle lasting through the night and into the next morning. The main problem that occurred was that one of the 8 Black Hawk helicopters crashed after losing its tail rotor, which is where physics comes in. Most helicopters have a single horizontal main rotor and a vertical tail rotor. A two rotor system is necessary because the main rotor produces torque in on direction which would cause the helicopter to spin out of control (a notable exception is the NOTAR system which involves a single main rotor and a ducted fan in the tail takes the place of a second rotor). The tail rotor provides a counter torque force (static equilibrium in one axis to move in a straight line) and rotational turning in the xz plane (other configurations include NOTAR and double main rotor configurations such as 2 coaxial rotors, angled meshed rotors, and front and back or side to side flat rotors). Anyway, in the movie (and real life) the Black Hawks tail rotor is blown off by an RPG causing the pilot to lose control as the craft began to spiral uncontrollably due to unopposed torque and crash. The operation was then updated to include the rescue the crew of the downed helicopter (who all unfortunately died). In the process many Americans were wounded or killed and a second Black Hawk was shot down the same way as the first causing even more problems. Having read the book In the Company of Heros, also by Mark Bowden, which is the true story Michael Durant (the pilot and only survivor of the second crashed helicopter who was taken prisoner and held for 11 days with a broken back and leg) I found the movie to be very close to the actual events and included the shootout in which two delta force snipers sacrificed their lives to protect Durant and a conversation that Durant actually had with one of Aidid's advisers. By the time the battle was over 18 Americans lost their lives with another 80 wounded. A dark day for the American military but a true display of courage on the part of all the soldiers involved.
