In this task you will use the constant acceleration formulas to measure your reaction time using a 1 m ruler.
You need to work in pairs.
Hold the ruler just above the persons hand so that the zero is down and as close to the hand as possible without touching.
Release the ruler randomly.
Note the distance the ruler has fallen. (You need to document how you measure this)
Repeat several times
Questions.
1. List all the data you know with the SUVAT values.
2. Which formula will you use?
3. What are the sources of uncertainty in this activity
4. Describe how one of these would effect your results.
5. Reaction times improve with practice and reduce with distractions design a method that could examine one of these more closely.
