1. Remove the pendulum mass from the rod, determine its mass and record below.
Reattach the pendulum mass to the rod so that it is flush with the end.
2. Measure the length of the pendulum from the center of the pulley to the center of
the pendulum mass and record in the table below.
3. Press record. Pull the pendulum back and release. Data recording will begin 5
seconds after the record button is pressed so pull back and release the pendulum
quickly. Data collection will stop automatically.
4. Record the maximum angle and maximum speed for the run in the table below.
Repeat steps 3 and 4 for four different maximum angles.
5. Calculate the loss of potential energy and the gain in kinetic energy for the runs.
Calculate their percent error.
