Reaction Time (GCSE Physics)

Which of these is a direct consequence of reduced reaction time for drivers in traffic?

In a simple visual reaction task, which sensory pathway is primarily involved?

A traffic safety campaign states: “Cut your reaction time and you reduce stopping distance.” Which part of stopping distance is directly reduced by a shorter reaction time?

In an experiment a subject’s reaction time is measured five times and values vary slightly. What is the main benefit of repeating the measurement several times?

Which change would be expected to reduce variability (spread) in repeated reaction-time measurements for a single subject?

Which behaviour will most likely increase reaction time in an emergency driving situation?

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

A subject’s measured reaction times (s) to a light are 0.21, 0.24, 0.20, 0.23, 0.22. What is the mean reaction time?

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

Which of these best describes the difference between reaction time and response time?

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)?
