Day 1
Objective:
TLW discover their reaction time using a novel approach
Terms:
gravitational acceleration, braking distance
In this activity you will be finding your personal reaction time for both your left and right hand by 2 different methods. In the first you will pair up with a partner and use the earth's gravitational acceleration (980 cm/s) to calculate your left and right hand reaction time based on how far a ruler falls [ t = sqrt(2d/980) ]. Then you will confirm using a web app. After that you will see how your reaction time affects the braking distance of an automobile using a web app.
* Part 1 : Ruler drop reaction time
* Part 2 & 3 : Mouse click and braking distance
* Show instructor your Journal with above 3 part report
