Part 1: What is your Reaction Time?

The average human reaction time for a visual stimulus is estimated to be about one-fourth of a second. Let's
see if your reaction time is quicker than that of the average person!
Using only a ruler, the acceleration due to gravity on earth, and your constant acceleration kinematics
equations, devise an experiment that allows you to determine your reaction time.
Questions to consider:
1. What quantity can you measure with a ruler?
2. What is the acceleration due to gravity on earth?
3. How do these two things relate to time, using constant acceleration kinematics equations?

Answer:

1. A ruler is a common instrument used for measuring the length of small objects

2. The acceleration due to gravity at the surface of Earth is about 9.8 metres per second per second.
