We set up a camera today. The yard stick was not in perfect position so I had to estimate some of the distances,
The times were 29 frames/sec on an MPEG4 camera.
(Dartfish software licensed to us free last year would have estimated all the measurements automatically-I miss it.)

Your tool estimates about 6-10 Newtons of force without much velocity sensitivity if I plugged it in properly.


We may decide to try lo lower the normal force and measure again.
