Experiment: Local Gravitation Acceleration
Experiment: Local Gravitational Acceleration Lab
In this experiment, we use the materials given to find the local gravitational constant of a free falling object.
PASCO Interface (for two sensors)
Control Box Transformer
Time of Flight Pad
Small Steel Ball (5/8”)
Large Metal Rod Base
Metal Rod (36 in)
Metal Rod (24 in)
Right Angle Clamp
y(t) - y0 = () gt2 + v0t
To begin the lab, we gather our materials and start setting up our station. After assembling the PASCO Discover Free Fall System, we hook it up to the GLX Xplorer program. To begin the procedure, we set up our rods and right angle clamp to a height that we would like to start out drops from. We attach our Drop Box to the rod extending out horizontal. We bring the metal ball up to the magnet and set the Time of Flight Pad directly below to calculate the free falls. Once we are ready for the ball to drop we hit record on the GLX Xplorer program and click our timer to release the ball from the magnet to land on the pad and calculate how many seconds it took to drop. After we do 10 drops we can then use the kinematic equation to solve for g.
Data and Results
Trial 1: 10 drops from the same height
