Re: [Phys-l] picket fence free fall vs. ticker tape timer



See

The Physics Teacher, Vol. 35, April 1997.

Vernier changed their coding of the data taking as a result of this
article, as I understand it.

|
| I remember reading an article last year on the error in using
| position-time data (like a ticker-tape) in calculating the
| acceleration of a freely falling object. In particular, I
| think it referred to using position time data from a "picket
| fence" apparatus with regularly spaced opaque and transparent
| strips falling through a photogate. I have searched my paper
| files and the internet to no avail. Does this sound familiar
| to anyone who could point me in the proper direction?
