Catch a Meter Stick
Description: This demo will quantitatively show the reaction time of the student volunteer.
This demonstration makes use of the following equation:
x = (1/2)g*t^2
Instructions: Hold a meter stick up and have a student hold their fingers beside the 50 cm point. At some random time drop the meter stick. Have the student grab the meter stick the instant they see you drop it. Measure the distance from the 50 cm mark to the point where they caught the meter stick. Convert distance to reaction time. t = square root of (2d/g)
Parts: One meter stick
Quant. in Demo Room: 1
