AT Cycle 34

🔴 2: T 4/4a, 🟡 4: M 4/3 - gravitational field

Today, we'll start with a brief discussion about potential energy versus position graphs.  We'll use a physical analogy of a hill as a model of how to think about these types of problems.  This discussion will help you solve the last problem in the required set below.  

Then, we'll take a look at some problems involving gravitational field:

    Required:  2001M2, 1999M2, 1995M2 (only peripherally related, but good to know about potential energy)

Homework:   Gravitational Field problems due to ✏️ Google Classroom Tuesday, April 18th at 10pm.  

🟥 2: T 4/4b, 🟨 4: T 4/4 - orbits & heavy rope

Today, start by finishing any problems from last time.  

Then, you'll work on the following AP problems to check your understanding of Kepler's Laws.

    Required:  1994M3, 2007M2

If you're wondering why 1994M3 part d has two correct answers that seem totally different, check out this article:

"Equivalence of Conservation of Angular Momentum and Conservation of Energy Methods for Satellite Velocity Calculations."

Homework:  Gravitational Field problems due to ✏️ Google Classroom Tuesday, April 18th at 10pm.  Orbit Problems also due to ✏️ Google Classroom Tuesday, April 18th at 10pm.  (All of these problem should be doable within the confines of class time, after all you have approximately 2 hours to do 5 AP problems which are 15 minutes each, so my expectation is that you would upload everything by the end of your last class period before spring break.  I am only extending the deadline to Tuesday, April 18th at 10pm as a courtesy to you, but try to stay focused and get everything done well before then since you should be studying for the mocks right after spring break.)  

ALSO REQUIRED ✏️ heavy rope problems (do on your own)

Also, watch the following two videos - they're the same problem with two different methods which are both useful: 

• Method 1:  small mass dm, constant applied force, finite distance y

• Method 2:  whole mass remaining, changing applied force, force constant for very small distance dx

Do some AP Problems that involve the concept of heavy ropes.  due to ✏️ Google Classroom by Sunday, April 23rd at 10pm.  

Required:  2009M3, 1975M3

For all days following spring break leading up to the mocks and to the actual AP exam, we will just be studying during our class time together.  This will be an opportunity for you to collaborate, review old material, and ask questions.
