Freefall - Physics Lab

EXPERIMENTAL PROCEDURE

1. Place the freefall apparatus on the desk and plug in the cord.
2. Connect it to the laptop to use the graphical analysis software.
3. Place the steel ball in the release mechanism by attaching the electromagnet to the top of the freefall apparatus.
4. Place the pad where the ball falls to catch the ball-bearing.
5. Turned the current to the electromagnet off to drop the steel ball.
6. When the ball lands on the pad, the timing will stop. Read the time on and record this as time (s).
7. Repeat the data taking the process at different heights for five trials.
