Timed AP C Exam Practice Videos
  • Below are videos from the AP that are timed AP Practice Exams.  There will be a timer on the video just like during the actual AP exam.
  • Monday and Wednesday there will be new practice tests while on Tuesday and Thursday the answers to these tests will be reviewed. On Friday there will be a video on tips, tricks and best wishes from the AP.
  • AP Physics C Mechanics - Review of Timed AP Exam Practice #1
    • Question #1 Alternate Solution - one is not better than the other, just different.
      • Part (A)
        • Since the force and the dart mass are the same for any length tube, Newton's 2nd Law says that the acceleration of the dart is also the same for any length tube.  For a longer tube, this acceleration would last longer and therefore the dart would emerge at a faster speed.
        • Since the retarding force of the block on the dart and the dart's mass are constant regardless of dart speed, Newton's 2nd Law says that the acceleration of the dart inside of the block would be the same.  Due to the dart's faster speed when it hits the block, it would spend less time accelerating in the block, therefore slowing down less and emerging with a faster speed Ve.
      • Part (D)
        • Using Newton's 2nd Law, divide the Force by the dart mass to determine the acceleration of the dart. Then take the integral of the acceleration with respect to time from 0 to 2 seconds to determine the velocity at 2 seconds.
     
    • Question #2
      • Part (C)
        • I will be extremely disappointed in the AP if they actually want all of that algebra shown as they claim you should be able to easily type your answers with no diagrams and that was anything but easy.  Instead I hope they would want something like:
          • Use the kinematic equation h=1/2at^2 to calculate the acceleration of each hanging mass.
          • Use these accelerations and Newton's 2nd Law applied to the accelerating hanging masses to determine each tension in the string using tension = mg-ma
          • The tension in the string exerts a torque on the PVC pipe equal to torque = tension x r.  Calculate the torque exerted for each hanging mass.
          • Since, a = alpha/r, and the tangential acceleration of the outside of the PVC pipe is equal to the acceleration of the masses, use the previously calculated accelerations to calculate the angular acceleration alpha.
          • Graph the torque vs. the angular acceleration.
