Schedule and assignments for P105, Spring 2012

Updated weekly. Last updated: 4/23/2012

NOTES:

This is a tentative schedule, which will be updated as we go through the semester. Check this web page for updates to this schedule every week.
Read the reading assignments ahead of the class meeting. Most of the class time will be spent discussing the chapter (student participation), or doing exercises that assume you have read the material.
In-class exercises will be collected and count as homework. You may turn those in up to one week late for partial credit if you missed class.
This is a link to most of the references (videos, graphs, etc.) presented in class (but a few videos and sound samples are copyrighted so I cannot put them on this web site).
List of topics covered.
List of quiz hints and notes.
NOTE: No computers or smart phones during class group work (trust me).

Week	Assignments

Wed.: Group work on Newton's laws: Motion Qs 1, 2, 7, 8, 9, 10; 1stLaw Qs 2, 3, 4, 6, 8, 10, 12, 13. 2ndLaw Qs 1, 4, 6+7, 9, 10, 11; 3rdLaw 1, 2, 4, 6, 7, 8, 10 in Handout 1. http://www.youtube.com/watch?v=3Lg3kg2QFgg http://www.youtube.com/watch?v=ZaDdwA30_20 Homework: Finish Handout (we will go over it before the quiz next Wed.) Homework: Play with this simulation for 10 min. Click on the Friction tab and answer this question: What is the difference in behavor of appling force with and without friction?
1/16	Discussion on Pressure. In Class: Monday: No class (MLK day). Wed.: Quiz! Group work: Density; 1, 2, 5, 6; Pressure; 1, 2, 3, 6, 8, 10, 11 in Handout 2. Homework: Finish any group problems you didn't get to in class, turn in next class.
1/23	Discussion on Energy. In Class: YouTube on energy conservation: Bowling ball, roller coaster. Simulation on energy conservation: spring, incline. Here is a few . Slides on the Second law Monday: Group work: Problems 2, 5, 7 on page 15 in the book and Handout 3: 1, 2, 3, 5, 6, 7, 8, 12, 13. Wed. Quiz!; More on Energy and Power. Group work: 14, 11, 12, 13, 14, 15, 6, 17, 18, 19; Power: 1, 2, 3, 5, 6; Thermo: 1, 6. Homework (Due next Monday): Download and play with the Skate Park Simulation. Click on clear heat, pie chart and bar graph. What is the relationship between Kinetic, Potenial and Total energy? (Be specific! Use the concept of conservation of energy to explain what you are seeing.) Describe what happens if you start the skater futher up on the track. Click on the Track Friction Button and add a little friction. Describe the relationship between the different kinds of energy if there is friction. Use the concept of conservation of energy to explain what you are seeing. Download and play with the Spring Simulation. Turn the friction off, set g = 0, hang a 100g weight on the 3rd spring, pull it down and let it go. In the show energy box, click on spring three. The total energy, the spring potential energy (PEelas), the graviational energy (PEgrav), the kinetic energy (KE) and the thermal energy (Thermal) are shown. Carefully describe what happens to these different energies as the spring bounces up and down (You may want to slow the simulation down to 1/4 time to see what is going on). Be sure to describe the relationship between the different kinds of energy (as the spring potential energy goes down the kinetic energy ....?). Describe the relationship between the different kinds of energy if there is friction. Describe the relationship between the different kinds of energy if there is gravity. In this simulation, what happens if you put a different mass on the spring? In this simulation, what happens if you change the stiffness of the spring? Homework: read Chapter 1&2 in the book.
1/30	Discussion on Simple Harmonic Motion. Note that we have covered everything in Chapt. 1 and 2 (although not in the same order). In Class: Handout 4: 1-16. Monday: Simple Harmonic Motion. Do questions 1 through 11 for homework, turn in Wed. Wed.: Resonance. Do questions 1 through 7 and do the 5 questions in the "other examples" section (download the other simulation), turn in Monday.
2/6	Discussion on Chapter 3. In Class: Monday: Waves. Finish Handout 4, start Handout 5. Homework: Answer question 1-6 on Waves. Wed.: Quiz! Wave Speed . Homework: Questions 1-11 on Wave Speed; Read Chapters 4&5.

4/23	Last class. Last quiz. Handout and go over: Takehome Final.
4/25	I will be in my office at class time to answer any questions (you can also reach me by email).
4/26	We will have an external reviewer on campus who is doing a review of the physics program. We want him to talk to some students so it would be really great if you could drop by PS200 (upstairs) at 1:45 to answer some questions from him. Thanks!
4/30	Take home final is due! Email or under my door (PS101b) is fine. If you email be sure I respond saying I got it! 10% penalty for being late. Note: I will NOT be on campus that day, someone will pick up the finals and bring them to me.
