Reaction Time (GCSE Physics)

Which of the following best represents a typical minimum simple reaction time to a sound for a young, alert person?

A snowboarder practices reacting faster to a gate. Which training will most likely reduce their reaction time?

If a driver’s speed is 72 km/h and their reaction time is 0.75 s, what is their thinking distance? (72 km/h = 20 m/s)

If a driver’s reaction time is 0.6 s and the car speed is 20 m/s, what is the thinking distance (distance travelled during reaction)?

When converting speed from km/h to m/s for reaction-time distance calculations, which factor is used?

Why does alcohol generally increase (worsen) reaction time?

Which emergency safety recommendation is directly aimed at reducing drivers’ reaction times?

A reaction-time experiment records reaction times with standard deviation 0.05 s. If you average many trials, what happens to the standard error of the mean?

In a simple driving scenario, which calculation gives the thinking distance (in metres) when speed is in m/s and reaction time in s?

In laboratory reaction-time tests, why is it important to randomise the time interval before the stimulus appears?

A sports coach wants to test athletes’ reaction time to sound. Which change would make the test measure auditory reaction time rather than visual?
