Model No. ME-6810 Time of Flight Accessory

Introduction
The PASCO ME-6810 Time-of-Flight Accessory is for use with
PASCO Projectile Launchers. It consists of a piezo-electric speaker
circuit mounted on a 20 x 20 centimeter plastic plate. The plate has a
signal cable with a 6 mm (1/4”) stereo phone plug. When a ball hits the
plate, the speaker circuit generates a Photogate-like pulse. The cable
sends the signal to a timer. The Time-of-Flight Accessory was
designed for use with a PASCO Photogate Timer or a PASCO
computer interface (such as the ScienceWorkshop Interface
®
or a
PASPORT Photogate Port with USB link) for Macintosh
®
or
Windows
®
computers.
Setup Options
The Time of Flight Accessory can be used with a Photogate Timer or a
computer interface for time of flight or initial speed studies. If using a
computer interface, you will also need data collection software, such
as DataStudio. If you plan to measure initial speed and time of flight in
the same experiment, you will need two photogates for the setup.
