His first experiments involved driving a simple pendulum with a pulse motor. He discovered that the easiest way to keep the pendulum moving was to use a coil to detect when the it reached the ...

Experiment with three pendulums that are 1-ft, 2.25-ft, and 9-ft long. Determine how many times the 2.25-ft and 9-ft pendulums swing during the time it takes the 1-ft pendulum to swing 30 times.

In the lab situated at the CSD, the apparatus is connected through motors and sensors. “In the case of a simple pendulum, our lab allows students to understand what the time period is (the time ...
