Finding g with a pendulum
(Full write-up at bottom)
Purpose:
Use the formula for the period of a pendulum to find gravity.
Materials:
· Photogate
· Meter stick w/ holes
· CBL cable and calculator unit
· Stand to hold photogate
· Paper Clip
· C clamp
· Play dough
Procedure:
C clamp a paper clip to a desk to hang the meter stick on to act as a pendulum. Use the piece of play dough to prevent the meter stick from sliding off. Using the CBL unit measure the period that the meter stick swings at different distances c from the center of mass. Record the data and using a linearization of the pendulum period formula calculate gravity from the slope of the best-fit line.
