Physics 151/201

What does it mean for an object to be in motion? More specifically, what is the cause of motion? How can it be measured, or quantified? Is it possible to think something is in motion when it is truly standing still? And is there a maximum speed of that any object can move? In this course, we will engage in a careful study of dynamics—the science of the causes of motion and rest—paying particular attention to the ideas of space and time. We will focus on reading selections from Galileo’s Dialogues, Pascal's Physical Treatises, Newton’s Principia and Einstein’s Relativity. Weekly laboratory sessions complement our classroom discussions. I look forward to our time together this semester studying some of the most significant and insightful works on physics that have been written!

All my lectures can be found on my youtube channel as a playlist. Henceforth, I will use this course web page to post solutions to homework problems and to notify you as to where you should be on my lecture video playlist.

• Force and Rotation Lab: On Friday, April 3, Prof. Schindler and Dr. Kuehn videotaped ourselves doing the Force and Rotation laboratory (asgv2_ex. 20.3). I have posted the associated videos. You should watch them all and carry out the requested calculations and data analysis. The lab reports will be due by Saturday at midnight (the night before Easter). By the way: the hanging mass was 456 +/- 5 grams. You'll need this to calculate its momentum while it is swinging around.
• ASG v2 Ch19: Watch all of the videos for Chap 19 by the night of Good Friday. asgv2_ex19.1, asgv2_ex19.2
• ASG v2 Ch20: Watch all of the videos for Chap 20 by the night of Tuesday, April 14. asgv2_ex20.1, asgv2_ex20.2
• ASG v2 Ch21: Watch all of the videos for Chap 21 by the night of Friday, April 17.
• Collisions Lab: On Friday, April 10, Prof. Schindler and Dr. Kuehn videotaped ourselves doing the Collisions Laboratory from ASG Chap. 22. You should watch the videos and carry out the requested calculations and data analysis. The lab reports will be due at midnight on Monday, April 20. By the way, here are links to the logger pro data we collected for Newton's third law, Newton's second law, and Conservation of Momentum. You should be able to right-click on these and save them as .cmbl files, which you can open with a free copy of Logger Pro (see links on the sidebar).
• ASG v2 Ch22: Watch all of the videos for Chap 22 by the night of Wednesday, April 22. Do asgv2_ex22-1, asgv2_ex22-2, asgv2_ex22-4. I have included a youtube video showing how to solve exercise 22-1.

You should watch the three relativity experiment videos and the one data analysis video. One of the main points of the lab is to determine (using the measured weight of the suspended mass) (i) the speed of the elevator and (ii) the height of the elevator shaft. Here is a copy of the Logger Pro data file with some of the analysis done. You might need to "right click" the data file link and save it as a .cmbl file on your desktop in order to open it with Logger Pro. The lab reports will be due at midnight on Friday, May 8. By the way: you do not need to know anything about Einstein's theory of relativity in order to do this laboratory experiment.
• Final examination: For the final exam in PHY 151/201, I will be posting an exam on MyWLC. It will be available for download at the beginning of the scheduled exam time (10:30 - 12:15 on Monday, May 11) . You will need to download the exam at 10:30, take it, and upload it to MyWLC by 12:30. There is a late submission grace time until 12:45. You may use your class textbook (physical or e-book), but nothing else (no notes, homework, etc., calculators, or other electronic devices). Here is a copy of last year's final exam.
• Study session: On this Friday (May 8) from 9:30 - 11:30, Dr. Kuehn will hold a final exam review session on zoom. During this study session, I plan to go through the answers to the final exam from the spring of 2018 (the final exam from -two- years ago. Note: this is not the one I posted last week from last year).
