Gravity Lab Investigation

Problem: Which ball will take longer to reach the ground, if dropped from 1 meter, 2 meters, and 3 meters?

Hypothesis: The Ping Pong Ball will take longer to get to the ground because it is lighter than the Golf Ball and is more affected by wind resistance.

Materials: Computer
Vernier Software
Logger Lite
Motion Sensor
Golf Ball
Ping Pong Ball
Meter stick
Styrofoam

Observations/Results: Our results looked like this:
