Abstract:
(purpose)
The purpose in this experiment is to learn how to measure simple
harmonic motion. This will be achieved by setting up the photogates and
pendulum correctly and learning how to graph the results.
(procedure)
• First task is to change the length of the pendulum to 20 cm from the
point of support to the center of mass of the knob. After adjusting the
pendulum correctly, we need to set up the photogates.
• To set up the photogates correctly they must be arranged so that
when the pendulum is hanging straight down it blocks the gate. Also
make sure while the pendulum is swinging the photogates will not be
hit or slightly scrapped.
• After setting up all devices properly, open up LoggerPro, click on
Pendulum Timer, and adjust settings accordingly.
• After recording 20 timed oscillations, record the mean and standard
deviation of the measured period by using LoggerPro.
• Lastly, repeat all this for lengths 40, 60, 80, 100, 120, and 140 cm.
