Reviewing for the First Semester Final

Here are some questions from the end of Chapters 7 and 8 about Energy, Work and Power

Ch7.  15, 23, 33, 37, 51
Ch8.  23, 35, 39, 49, 55, 69, 89

Here is a link to the AP Physics C Course Description.  On pages 16-25 they list the learning objectives in careful detail - a giant list of what we should learn in this class, and the only real list of what concepts and problems might be on the test.  We have covered sections A- D at this point.

Here is a link to a site with numerous practice tests, each 2-20 MC questions about topics of a particular type.  After you do the questions they will show you solutions.  It will ask you many times to sign up for their tutoring services, but it never seems to require you to do it.

As always the link to the practice AP FR questions remains a good source for practice with answers, and there is the new set of homework questions.



You can also use UT quest to make a customized review set of questions, focusing on all of the homework questions that you missed the first time around.  Follow these steps  (copied from their help menu)

• Customized Review 
• To help you review for an upcoming test, use the Custom Review option to create customized reviews that focus on your weakest areas. Choose Grade Summary from the left menu, then the Grades by Subject Area link to see the Custom Review option.  

The Bungee Jump

From a designated height, and using a given minifigure and spring, determine how much string must be added in order that the bungee jumper gets as close to the ground as possible.


Take a photo of your calculations and attach them to your answers to the three minilab questions.  Put them in your lab document.

Derivation of velocity equation with Air Resistance

The derivation of the equation for the velocity of an object experiencing air resistance was long and tricky.  I've prepared a PDF of it with notes about the steps.  You can find it here.

There is a minor mistake in the middle of the second page.  Twice I write dt instead of u, in the denominator of the right hand side of the equation.  This is in the section that I've labeled "now collect terms and integrate."

Flying Pigs

Take measurements of the pig's mass, and of the radius, period and the angle of the string's deflection from vertical as it flies in circles.  Calculate the tension in the string in two different ways.  (1.  based on the weight, 2. based on the net force.)
Do the 2 methods come within 5% of each other?  If not, what went wrong?
