for return shipment will not be covered by the warranty.)
Shipping costs for returning the equipment after repair
will be paid by PASCO scientific.
Suggested Experiment
Verify the Acceleration Sensor's Performance in the
Earth's Gravitational Field
1 Connect the Acceleration Sensor to the computer
interface with the interface cable (see Figure 1a) and
set up Data Studio as detailed on page 2. Open a
Digital Display and select Acceleration (g) from the
pop-up menu. Set the filter switch on the sensor to
SLOW.
2 Place the sensor flat on a level surface with the arrow
indicating direction of sensitivity parallel to the
ground (Figure 3a) and press the tare button.
3 Orient the sensor so the arrow on the label is
perpendicular to the ground (see Figure 3b). Click
Monitor Data under the Experiment selection menu in
Data Studio.
4 Observe that Data Studio is displaying a value for ac-
celeration of either plus or minus 1 g.
5 Rotate the sensor 180° around its major axis so the
arrows point in the opposite direction.
6 Observe that Data Studio now displays 1 g with the
opposite sign as observed before.
7 Can you imagine a way to measure the tilt angle of
the sensor? (Hint: tilt angle = sin
-1 (acceleration
in g).

earth's gravitational field.
Suggested Activities
1 Measure the acceleration of a Dynamics Cart down an
inclined Dynamics Track.
2 Measure the acceleration during collision of a
Dynamics Cart.
3 Measure the acceleration during free fall.
4 Measure the acceleration of an elevator, automobile,
or roller coaster using the remote data logging
capability of the 500 series computer interface.
