where did the other versions (with more than one slide per page) of the presentation go?

Brian - we are no longer posting all of the versions. We are posting the 1 slide per page PDF, you can then go into print options and format it the way you would like it to print. This link explains that. https://helpx.adobe.com/acrobat/kb/print-multiple-pages-per-sheet.html Also, you could print directly from the SMART Notebook presentation. If you want the 3 slides per page with lines, you would need to print from SMART Notebook.

Energy Presentation: Question #16 answer choices need to be revised to reflect the correct "tab" response of 882J. Thanks!

Thank you. I fixed this answer in the presentation.

Energy Presentation, question #54, the work is correct, however the answer should be v = 0.93 m/s.

Ryan, Thank you. All fixed. Yuriy

In slide # 74 it says that "no external force acted on the system". Perhaps it's worth explaining why we are not considering the fact that Earth is acting on the falling object.

Benjamin, this is a bit tricky - and is actually explained better in the AP C Physics course. The force of gravity is a conservative force, so it is taken into account with the GPE expression. The work done by gravity as the object falls is calculated and is called GPE. External forces are typically things like friction (non conservative force), or a person pulling on the object and getting it to move.
