Free Fall Experiment

Determine the gravitational acceleration near the surface of the earth

1. Faber-Castle click pen

2. Phypox App - Acoustic Stopwatch

3. Paper clip

1. You are going an acoustic stopwatch from Phyphox application, acoustic stopwatch means that it uses sound as a start and stop trigger

2. Attach the paper clip to the end of the clicker pen (ballpoint end)

3. Set the falling height of the paper clip from the floor

4. When you release the click pen, the sound from the released will trigger the start of the timer

5. When the clip fall onto the floor, the sound it makes will trigger the stop of the timer

6. Thus, the timer will give you the falling time of the paper clip

7. Record the measurement in the table

8. Use appropriate equation graphing tools to analyze your result.

9. State the significance of your findings.
