CHAP 11 AND 12 OSCILLATIONS, WAVES AND SOUND AP Physics

March 5 Learning target: I can understand the importance of keeping up in Physics Question: What do I need to turn in today to improve my grade in Physics? Vocabulary: 1. oscillate 2. restoring force 3. spring stiffness constant (all found on pg. 293) Anyone taking the AP test needs to sign up by Thursday. Today you must work on all missing assignments, I will not take anything from before Chapter 11 after Friday---no exceptions!! Go over Homework: pg problems 2, 5, 15, 23 and 29: Due today. New Partner problems-see next slide Homework: Read pg Open note quiz on this section Friday. Make sure to focus on the terms.

Mrs. Painter’s Rant Many of you have a lot of missing work and are not keeping up with assignments. Whether or not you are taking the AP test, this is an AP class and it is critical you do the homework, you do not want this class to pull down your GPA. Today you are being given a gift, a day to catch up and stay caught up. Use this time wisely. Help each other. If you need past lifelines they can be put up on the screen. If you need to check your answers, the keys are available. I will accept work for Chapter 11 up to this Friday and this Friday only! From now on work is due on the due date-no exceptions.

Quiz March 3 Answer “Misconception Questions” 1-5 on pg 321

Problem partner You will receive a new card partner You and your partner will receive one problem from the book to work together on. You will work on this together, you may check with me for the answer and solution once you have an answer You will then work this problem with the class, using good problem solving techniques (meaning you list knowns, unknowns and units. Show all equations and show any substitutions used.

Card partners

Quiz March 5 What is the equation for Hooke’s law? When an object moves back and forth and each oscillation takes the same amount of time the motion is______________. The maximum displacement from the equilibrium point is called__________________. What is the equation for period T? The larger the mass, the________the period.
