2. Bellwork What is displacement? The distance in a given direction

3. Your Reaction Time Activity 9/11/13

4. Reaction Time Distances Type of release Initial Displacement (m) Has to be non-zero Final Displacement Trial 1 (m) Final Displacement Trial 2 (m) Final Displacement Trial 3 (m) Final Displacement Trial 4 (m) sight hearing touch

5. Pre-Lab: Which of the three senses do you think will be your fastest reaction time?

6. Calculations: 1.Calculate the change of displacement for each trial 2.Calculate the average displacement for each sense. 3.Using a T-Chart (3 total), calculate each reaction time by using the average displacement (in meters). 4.Using a T-Chart (3 total), calculate the average velocity that the meter stick is traveling as you catch it for each of the senses.

7. Questions: (Answer in complete sentences.) 1.What sense had the fast reaction time? 2.Was your pre-lab prediction right? 3.Why do you think this was quicker than your other senses? 4.How does your best reaction time compare to hitting a base ball thrown by a major league pitcher? (t = 0.18s) 5.What factors might have contributed to your reaction time being too slow or quick? Be specific!
