This Concept Map, created with IHMC CmapTools, has information related to: Christina Polk - Cloud Computing CMAP, Helicopter dropped from 1 meter Results Average speed = 0.98 m/s, Which helicopter will have the greatest average speed? One dropped from 2.75 meters, or one dropped from 1 meter? Hypothesis The helicopter dropped from 1 meter will travel faster than the helicopter dropped from 2.75 meters, The helicopter dropped from 1 meter will travel faster than the helicopter dropped from 2.75 meters Experiment Helicopter dropped from 1 meter, Average speed = 0.98 m/s Thus Hypothesis NOT supported, The helicopter dropped from 1 meter will travel faster than the helicopter dropped from 2.75 meters Experiment Helicopter dropped from 2.75 meters, Helicopter dropped from 2.75 meters Results Average speed = 1.16 m/s, Average speed = 1.16 m/s Thus Hypothesis NOT supported, Hypothesis NOT supported Why? Possible Explanations 1. Gravity was stronger than the spinning of the paper 2. Our ability to start and stop the timer was less accurate on the lower height treatment 3. Our sample size was too small to detect differences
