AP-B+November+Calendar

November 1
Work and Energy Exam objective (60 minutes)

Homework Outline Ch 6 Momentum and Center of Mass. (Note Center of mass is not part of the AP-B exam, but is a part of the AP-C exam.)

November 5
Take home Exam Due. Outline of Ch 6 due

Objective: Be able to define when momentum is conserved or not. Define Impulse and momentum as working definitions. Apply Momentum concepts in linear and glancing situations. Why: Develops deeper understanding of particle interaction and critical thinking situations. How: Demonstrations and video analysis of collisions. Problem solving.

Objectives above continued see Nov 5

November 8
Objectives above continued see Nov 5 27, 33, (36 demo in class) Section 6.4 p 197 #37-40, 47, 51, 58, 63, 65

November 13
Objectives above continued see Nov 5

Review Assignments/ Questions and examples. Ballistic Pendulum Example/ pool table?.

Discuss center of mass analysis. (Hand out for AP center of Mass, concepts. //From AP-B Barron 2010//) In class groups solve AP open ended questions. Due end of class.

Section 6.5 Center of Mass p 200# 81, 87, //AP C Students solve some of the end of chapter problems on center of mass. and see notes on handout.//

November 15
Review previous assignments.

Quiz on Momentum Concepts (smaller Quiz) (40 minutes)
10 MC questions. And 1 open ended Question Intro to circular motion. convert from radians to degrees. Determine the centripetal force, acceleration, speed, period, rotational speed of an object spinning in a circle.

HW: Outline Ch 7 Circular Motion and Gravitation.

November 19
Ch 7.1-7.3

Watch Dr. Lewin from MIT. Describe angular measure and convert between radians and degrees. Define period and frequency. Identify the cause of the centripetal force by applying Newton's Second Law. How: Use examples of roller-coasters, cars on curves etc. Explain why there is a centripetal acceleration in constant or uniform circular motion, and compute centripetal acceleration, velocity, radius.

November 21&27
// ***I am missing Nov 15** //** //quiz material from a number of students. Please try to make up asap.// *** Ch 7.5 Describe Newton's Law of Universal Gravitation and how it relates to the acceleration due to gravity. Apply the general formulation of gravitational potential energy. Be able to Derive Kelpers 3rd law. Why: General understanding of the universal gravitation laws provides general understanding of how our planets satellites and the entire remains in its state of motion. How: thought experiments, demos, problems and derivations.

P 236 #19, 23, 25, 29, 36-39, 43, 49, 51, 53-56 (in Class) //Some we will work through together.// Experiment demo #72 p 240. materials: Cup with holes, water, beaker, candle, match, ipad video.

Over Break: p 240 #70, 78, 81, 90,101, 103, 110

Thanksgiving Break. When we come back we will move into Ch 8 Rotational Motion and Equilibrium

November 29
Define torque and center of mass.

Torque causes a change in rotation. Not we see that a force can cause a rotational motion at the same time as a translation. We aim to understand and apply both concepts. We can also now see that static equilibrium can only occur when not only the net force is zero, but the sum of the torques are also zero.

p 277 #29-33 odd.

We are looking at a** test on Ch 7 and 8 ** focusing on centripetal forces, acceleration and torque on ** Wednesday December 5 **
