1C20.15 - Free-Fall - Dropping Balls

Code Number:
Demo Title:
Free-Fall - Dropping Balls
Free Fall, Terminal Velocity
Area of Study:
Pizza Pan, Set of Balls with the Same Diameter but Different Densities, Golf Ball, and Ping Pong Ball.

Choose any two different mass balls from the set and drop them from the same height onto the pizza pan.  You should be able to hear that they hit the pan at the same time as expected.  Repeat the experiment with the golf ball and Ping Pong ball and you should hear that they hit at different times.  This shows that the air has a much greater effect on the Ping Pong ball due to its larger diameter and small mass.  In effect it reaches a terminal velocity very quickly which is not seen with the golf ball over the short drop distances used.
