AT Cycle 33

🔴 2: F 4/4 🟡 4: F 4/4, 🔵 8: F 4/4 - oscillation problems (2)

Today, we'll start by going over any assessments that we have not yet reviewed.  

Then, we'll be reviewing many different aspects of oscillations including kinematic variables, forces, and energy in an oscillating system.  

Next, in groups, apply what you know and solve problems with simple harmonic motion.  

    Required:   Oscillation AP Problems (2009M2, 1990M3, 1999M2)

With any time remaining, catch up on any of the problems that you skipped.  More Mechanics Unit Assessment on Thursday, April 10th (marking period 3).  

🟥 2: T 4/8 lab, 🟨 4: M 4/7 lab, 🟦 8: M 4/7 lab - physical pendulum lab

Today, we'll design an experiment to find the moment of inertia about the center of mass of an odd shaped object.  In order to do this, you'll have to understand the motion of a physical pendulum.  Once you finish taking data, you'll finish your brief individual write-up of this lab.  Do your write-up on loose 0paper which you can turn in in hard copy.  Your analysis should include a labeled sketch of the set-up, at least one free body diagram, sentences about what you did and why, and calculations necessary to find the moment of inertia about the center of mass.  YOU MUST DO AT LEAST TWO DIFFERENT TRIALS to verify your calculation of the moment of inertia ABOUT THE CENTER OF MASS.

Homework:   Make sure you've finished all of the problems up to this point.  If you skipped orbits, Kepler's Laws, and heavy rope problems, look back at those now.    📄Physical Pendulum Lab write-up due on paper in class Thursday, April 10th (the day of the unit assessment).  More Mechanics Unit Assessment on Thursday, April 10th (marking period 3).  

❤️ 2: W 4/9, 💛 4: T 4/8, 💙 8: T 4/8 - study more mechanics

Today, study for your assessment on More Mechanics.  The focus of the assessment problems will be on the following topics:

• velocity dependent forces (including air resistance)

• oscillations (linear, rotational, LC circuits - see below)

• heavy rope

• gravitational fields

• orbits & Kepler's Laws

• ...plus any background you need to know in order to solve problems on these topics.

Homework:    Study for More Mechanics Unit Assessment next class - Thursday, April 10th (marking period 3).
