Measuring a Bungee Jump
You’ve seen them on TV: bungee jumpers tumbling from the sky while bound to a long, elastic-like cord.
Bungee jumping is a popular activity in Canada but here at Ayva, we prefer to keep our feet rooted firmly on the ground.
When Dr. David Kagan from Chicago State University accompanied a student on a bungee jump, he videotaped the event and was surprised to learn that his student’s acceleration was greater than the acceleration due to gravity. This inspired PASCO employees to use their own Rotary Motion Sensor to simulate the jump in the lab.
PASCO product development specialist John Hanks headed the experiment, which was conducted by connecting a thick rope – used to simulate the bungee cord – to the motion sensor. When Hanks dropped the rope, the sensor recorded the fall, which collected results similar to that of Dr. Kagan’s. According to the Rotary Motion Sensor, the rope accelerated at a speed of approximately 12 m/s² near the end of the fall – once again faster than that of gravity.
