Velocity Lab Investigation

For this lab, we dropped a ping pong ball and a golf ball from 1 meter, 2 meters, and 3 meters, three times each, using both a meter stick and a motion sensor. We did the golf ball first. With the meter stick from one meter, the three speeds were 0.2, 0.3, and 0.3 seconds, and the velocity was 3.3. At 2 meters, the three speeds were 0.8, 0.6, and 1.1 seconds, and the velocity was 2.8. At 3 meters, the three speeds were 1.1, 0.9, and 0.7, and the velocity was 3.3. Then, we did the ping pong ball with the meter stick. At 1 meter, the three speeds were 0.5, 0.6, and 0.5, and the velocity was 2. At 2 meters, the three speeds were 0.7, 0.5, and 0.5, and the velocity was 2.3. At 3 meters, the three speeds were 0.7, 1, and 0.6 seconds, and the velocity was 3.75. Then we did the golf ball with the motion sensor. For every height, the speeds and velocities were pretty much the same, and the same with the ping pong ball. However, some things went wrong. One example of this is that the meter stick wasn't exactly a meter, and that probably affected the velocities and speeds. Another problem is that the motion sensor was hard to use, so we had to tape it to a meter stick. That may have had something to do with how it received the information. 

This shows the motion sensor after it was taped onto the meter stick.
