TECHNOLOGY-BASED LAB ACTIVITIES

2. Comparing results Repeat the experiment with a bottle of different mass.
Make sure the cord you use is appropriate, so that it stretches substantially
but does not reach its maximum extension or break. What are the similarities
and differences between the two sets of data? Discuss some methods
that might be used by operators of commercial bungee jumps to assure the
safety of jumpers of different weights.
3. Extending research Use reference books or the Internet to research the
accelerations experienced by astronauts during takeoff and re-entry. How
do the accelerations experienced by astronauts compare to the maximum
acceleration experienced by a bungee jumper?
4. Evaluating methods Place a motion detector on the floor under the bottle
during a “jump.” To protect the motion detector, place a wire basket upsidedown
over the detector and make sure the bottle will not hit the basket when
it falls. Examine the distance versus time and velocity versus time graphs of
the jump from the motion detector data. How do these data compare with
the accelerometer data? Which sensor do you think is a better tool for analyzing
a jump? Explain.
