    The video you guys asked about today is about 42 min and the part you asked about with gravity is at about 11 min. Its a long video so I uploaded it. You can play it in a webbrowser which can play an .mp4 .h264 video. : Most can. I don't know about macs but i think so.

    Wed Dec 4 A day 61 Ch12: questions[2,3,7,9,15,16] we will cover the start of Ch12 so that you can work on your homework this weekend. I know that Some chapters are skipped because they are not in Physics B. Statics is applied force balances. They can be very simple but the applications are everywhere. Todays lab uses the airtrack for Momentum.
    Thursday Dec 5 B day 62 we will use class to cover sample test problems in P, J and collisions on Friday. I don't intend for these to be the most difficult HW problems But the test will model both HW and sample questions given Tuesday.
