The Reaction Time Ruler Drop Test is a simple yet effective way to measure reaction time, hand-eye quickness, and attentiveness. It is often used as a science class project or in sports that require good coordination and quick reactions.
How Does It Work?
In this test, all you need is a ruler and a little bit of calculating. The test utilizes the properties of gravity to determine how long it takes a person to respond to the dropping of an object. By measuring how far the object falls before being caught, you can calculate the individual’s reaction time.

Test Procedure
To conduct the Reaction Time Ruler Drop Test, follow these steps:
- The person to be tested stands or sits near the edge of a table, resting their elbow on the table.
- The assessor holds the ruler vertically in the air between the participant’s thumb and index finger, aligning the zero mark on the ruler with the participant’s fingers.
- The participant indicates when they are ready, and without prior warning, the assessor releases the ruler.
- The participant must catch the ruler as quickly as possible as soon as they see it fall.
- Measure the distance the ruler fell (the level the participant grabs the ruler) in centimeters and record it.
- Repeat the procedure several times (e.g., 10 times) and calculate the average score.
How to Calculate Reaction Time
To calculate the average reaction time, use the formula:

t = √ (2d / g)
Where:
t = time the ruler was falling (seconds)
d = distance the ruler fell (meters)
g = acceleration of gravity (9.8 m/s²)
Alternatively, you can use the provided calculator or the table below to determine the time it took the ruler to fall based on the measured distance.

FAQ
Can this test be used to measure reaction time to a sound?
Yes, you can adapt this test to measure reaction time to a sound. The setup would involve the subject wearing a blindfold, and the ruler being released at the same time as an auditory signal.
Do results differ for the left and right hands?
Results for the left and right hands can be expected to be different. If comparing the results for both hands, it is important to control for this or at least record which hand was used for the test.
Conclusion
The Reaction Time Ruler Drop Test is a straightforward and informative way to measure reaction time, hand-eye quickness, and attentiveness. It can be conducted using only a ruler and some simple calculations. This test is widely used in science classrooms and sports that require quick reactions and good hand-eye coordination.
