Bell Ringer: Calculate your reaction time using a ruler (explained below)
Questions on homework?
Reaction time activity
Have a partner hold a ruler vertically, with 0 cm at the bottom.
Position your fingers to grab the ruler at the 0 cm mark.
Your partner will drop the ruler at some point, and you are to catch it as quickly as you can without moving your hand up or down.
Record the distance (in cm) that the ruler fell before you grabbed it
Use this information to calculate your reaction time
Acceleration of gravity lab
