As we'll see in an upcoming chapter, we can calculate the amount of time for an object to

fall if we know the distance it falls, and its initial velocity (zero in this case). Soon we will

learn why this formula works, but for now, just accept it as a gift and use it:

Calculate your reaction time as time, t = (2H/g) where H is in cm and g = 981 cm/s^2

t =

Find the uncertainty of the time. Show your calculations:

Uncertainty in reaction time, t = s

The average reaction time for a young adult to respond to a visual stimulus is 0.200.025

seconds. Compare your value of reaction time with this standard value and find percent

error.

Answer following question in the discussion section.

Q1: Based on this test, is your reaction time faster, slower, or the same as the average

reaction time?

Q2: Find out definition of reaction time from internet and write it. How can reaction

time affect your life?

Q3: What factors does reaction time depends on?

(b) For Technical experiment:

Use following link to check your reaction time when you use technology like laptop or

computer. https://humanbenchmark.com/tests/reactiontime

This is simulation-based test of your reaction time how fast you can react to laptop or

computers.

Follow instructions appear on the webpage when you click this link. Do 5 trials on screen

to get 5 reaction time. Record time and change unit of time from ms to s. (1ms = 0.001 s).

Find average of reaction time. This is your technical reaction time.

Question 4: Compare your reaction time between manual and technical methods and

find out percent difference between them. Write about how they are different?
