Set up the motion detector on the floor
Turn on the CBL
Select apps
Select Easy Data
Distance vs. Time should appear
One person presses start
2nd person holds parachutist by the folds, two meters
above the sensor and listens for clicks
8. Drop parachutist above the screen of the motion
detector
9. Press stop as soon as the parachutist lands
Analyze
1. Press analyze
2. Press select region
3. Use cursor to select the area of freefall using the
arrow button (left and right boundaries)
4. With new graph select the X1 and Y1 values at
the top of the slope and the X2 and Y2 values at
the bottom. Write these values down
5. Calculate the slope (Y2-Y1/X2-X1) This is your
terminal velocity in m/s. Be ready to compare
to class results.
