Physical Pendulum Lab

Purpose:
Calculate the acceleration due to gravity of a pendulum using collected period data. 

Materials:
Meter stick, TI-84 calculator, CBL unit, ring stand, clamp, Photogate

Procedure:
  1. Clamp the paper clip to the desk at a height where the meter stick can swing freely.
  2. Use the holes on the meter stick to create varying distance from the center of mass.
  3. Determine the period of the pendulum using the Photogate.

Conclusion:
The acceleration due to gravity of the physical pendulum was found using collected data points, and an error of 14.69% resulted. The error could be due to irregular motion of the pendulum or the nature of the lab design.
