Record Data
1. Mount the Force Sensor on a horizontal support rod with
hook pointing down.
2. Press the Zero button on the Force Sensor to tare it.
3. Obtain a variety of objects of known mass, such as the
Hooked Mass Set (SE-8759). Hang a mass from the Force
Sensor hook.
4. Click the Start button and record data for 10 seconds.
5. Click the Stop button.
6. Repeat Steps 2
–
5 for each mass.
7. Using your data and the formula:
F = mg
(where F equals the force exerted by the mass, m equals the
mass, and g is the acceleration due to gravity), calculate an
average value for the acceleration due to gravity.
8. Imagine that you performed this experiment on the Moon
(where g is 1.63 m/s
2
). How would this experiment change?
Explain.
Note: Masses between 200
–
1000g yield best results.
