Introduction
The Force Sensor Balance Stand is designed to allow the use of a PASCO Force Sensor as a
balance. The sensor is mounted on a bracket and the circular balance pan is screwed directly
into the Force Sensor in place of the hook. When used with DataStudio, both weight and
mass can be determined with a Force Sensor and a stand. Both ScienceWorkshop and
PASPORT Force Sensors can be used with the Force Sensor Balance Stand.
The Force Sensor Balance Stand is ideal for usage in experiments exploring buoyancy,
gravitational, and normal forces.
Basic Setup:
1. Using the screws provided with the Force Sensor, mount the sensor on the balance stand. See
Figure 1 for the appropriate mounting positions.
2. Unscrew the hook from the top of the Force Sensor. Screw the balance pan into the
threaded hole on the top of the Force Sensor.
3. Connect the Force Sensor to either a ScienceWorkshop or PASPORT interface. (For
software setup, see Appendix A.)
4. Place an object on the balance pan. Try to center the object for best results.
5. In DataStudio, click the Start button to display the weight of the object.
6. Use the calculator in DataStudio to create the following equation, which displays the mass
in kg:

Setup Options
a) Mounting a Force Sensor
The Force Sensor Balance Stand can be used with three different PASCO force sensors (See
Figures 2a-2c below.)
b) Mounting both a Force and Acceleration Sensor
In addition, an acceleration sensor can be mounted to the stand to measure the angle of
incline. Depending on the force sensor used, the mounting position will vary. To mount an
acceleration sensor, use the bracket and screws provided with the acceleration sensor.

Hold the bracket against the side hole in the Force Sensor Stand. Insert a screw into the back
of the Acceleration Sensor and mount to the back of the stand. Insert another screw into the
bottom of the Acceleration Sensor to hold the sensor in place.
Note: If you are mounting a CI-6537 Force Sensor, mount the metal bracket to the front of
the Force Sensor Stand, as shown in Figure 5.

Experiment 1: Exploring the Buoyancy Force and
Archimedes’ Principle
Procedure:
1. Mount a Force Sensor to the Force Sensor Balance Stand (see page 5).
2. Screw the Balance Pan into the Force Sensor.
3. Place the stand on a laboratory jack.
4. Connect the Force Sensor to a computer interface (For
DataStudio Setup instructions, see Appendix A.)
To avoid the risk of electric shock, keep water and
fluids away from sensors, power sources, computers, and
electrical apparatus. Observe standard electrical safety
precautions in your classroom.
5. Fill the beaker with the desired amount of water.
6. Place the beaker on the Balance Stand; then zero the
Force Sensor by pressing the Tare button.
7. Hang another Force Sensor directly above the beaker, as shown in Figure 1-1.
8. Choose a metal cylinder that will fit the beaker.
9. Use the Force Sensor Balance Stand to measure the weight of the cylinder.
10. With thread, hang the cylinder from the upper force sensor.
11. In DataStudio, create a graph which displays the following:
a) Force measured by the upper sensor (apparent weight)

PS-2104)) Computer interface

b) Force measured by the lower sensor (buoyancy force)
c) Weight of the cylinder
12. In DataStudio, click the Start button to begin data collection.
13. Use the lab jack to raise the beaker until the cylinder is fully submerged in the water.
14. To end data collection, click the Stop button in DataStudio.
Analysis:
1. What happens to the apparent weight as the cylinder is submerged? Explain.
2. What happens to the buoyancy force as the cylinder is submerged? Explain.
3. How are the apparent weight, buoyancy force, and cylinder weight related to one another?
Explain.

Experiment 2: Exploring the Relationship Between the
Normal Force and Angle
Purpose:
To investigate the relationship between the normal force and the track angle.
Procedure:
1. Attach a Force and Acceleration Sensor to the Balance
Stand by following the instructions in the Setup Options
section (pages 5-6).
2. Plug each sensor into a computer interface. (For more
information, see Appendix A).
3. Place the stand in the middle of the Dynamics Track.
4. Place the 500 g mass on the pan of the stand. Use a small
piece of tape under the mass to secure it to the stand.
5. In DataStudio, create a calculation for the angle:
