I. a) Drop the helicopeter from a distance of 0.5 meters (50 cm) and record the time needed for the helicopter to hit the floor. Repeat this 4 more times for a total of 5 drops from 0.5 meters. b) Repeat this for 1.0 meter, 1.5 meters, 2.0 meters, and 2.5 meters.

 

Hypothesis: I predict that the graph produced by the average times versus distances data collected below will be a (straight line, curved line).
