Ch04 toss ball for analysis (halverscience)
For my Mt SAC Physics 2AG students.
--- A ball is tossed vertically.
Confirm that the time to fall up equals the time to fall down.
--- A ball is tossed across a street. Again, confirm the time to go up equals the time to go down.
--- A frisbee is tossed across the street. Since it is supported by air, its path is very different from the ball's.
This video was recorded at 30 frames per second. You can advance the video frame-by-frame by using the "." and "," keys. If that doesn't work you can still get frame-by-frame by (1) copying the URL address of this video then (2) going to this special web page: http://www.watchframebyframe.com/ and (3) pasting the URL into the address box.
I personally found that on the first toss, the ball went from eye level to the top in 25 frames. Guess how many frames it took to come back down to eye level?
Thanks to Makoto and Geoffrey for tossing the ball and frisbee.
