The old spark timer lab that
many of us used to teach had terrible acceleration graphs too.
I built a spark free-fall apparatus nearly 30 years ago. I use it with
a large induction coil and a half-wave rectifier. The apparatus looks
like a Rube Goldberg throwaway...but IT WORKS. I use 60Hz as the time
base and the ball falls about 1 meter I am able to consistently able to
get 'g' with less than 10% error.
we need to get back tothose PSSC type of equipment days when we used simple equipment and
_Made it Work_ and learned the frustration that accompanies all 'real'
physics inquiries.
