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:
or
6. In DataStudio, create a calculation for the normal force:
