Introduction
The PASCO Model ME-9283 Tape Timer easily and
accurately measures the motion of an object at two
pre-calibrated frequencies. A slower setting (10 Hz)
lends itself to most dynamics cart experiments,
whereas the faster setting (40 Hz) is ideal for free fall
experiments. This timing method is a visual demonstration of speed
and acceleration. A moving object pulls a paper tape
through the timer which prints dots on the tape at even
time intervals. The result is a series of dots in a line on
the paper tape representing the position of the object as
a function of time. From the dots on the tape, the
distance traveled can be measured and the average
speed for each time interval calculated.
The tape can be attached to air track carts, dynamics
carts, or falling masses.
