4) Visual Accelerometer with Fan Accessory (and Time Pulse)
The Visual Accelerometer can be
used with the ME-9491 Fan
Accessory for motion and constant
acceleration experiments. Use the
provided thumbscrews to attach the
Visual Accelerometer to a PAScar or
Dynamics Cart. The Fan Accessory
clips onto the side rails of the Visual
Accelerometer the same as it does to
a Dynamics Cart or a PAScar. The
Time Pulse Accessory allows the fan
to turn on and off, hands free. Set the
time pulse for about 1 second. This
will give a short acceleration, and then show a constant speed as it
coasts the rest of the way down the track.
Additional equipment required: Dynamics Track [1.2m (ME-
9435A) or 2.2m (ME-9458)], Dynamics Cart (ME-9430) or PAScar
(ME-6950), Fan Accessory (ME-9491), Time Pulse Accessory (ME-
9496)
5) Visual Accelerometer on Motorized Cart (with Time Pulse
Accessory)
The Visual Accelerometer
can be used with the ME-
9781 Motorized Cart for
motion and constant velocity
experiments. The Visual
Accelerometer attaches to
the Motorized Cart with
thumbscrews through holes in
the top of the cart (the same
way you attach it to a
Dynamics Cart or a PAScar).
The Time Pulse Accessory
allows the cart to turn on and off, hands free. Set the Time Pulse for
about 2 seconds. This will give a very short acceleration (as it turns
on), and then show a constant speed for the two seconds. Watch for
the very short deceleration as it turns off.
Additional equipment required: Dynamics Track [1.2m (ME-
9435A) or 2.2m (ME-9458)], Motorized Cart (ME-9781), and Time
Pulse Accessory (ME-9496)
