Nicholas Natale, Kyle Guzman, Conor O?Callahan, Paul Febles Physics H- Curran 3/26/14 Hypothesis: The two darts will hit the ground at the same time because gravity is the factor affecting them, and gravity is constant. Dart Experiment Procedure Materials: 2 Nerf Dart guns 2 Darts (one weighted with metal beads) Metal Beads Camera Procedure: We will test the reaction time of the guns when the trigger is pulled to make sure that they are uniform. (This will be tested 3 times) We will shoot the darts from a balcony at the same height and two people will be below the drop site. One person will shoot both guns so they will be fired almost at the same time. We will rotate who shoots the guns in order to make sure person shooting has little to no effect on results.
