WebKey Concepts: Your nervous system allows your body to react to different stimuli (external events). Reactions can be voluntary (eg: swinging a bat at a ball flying at you) or involuntary (eg: blinking at a puff of air). A reflex is a rapid, automatic response to a stimulus WebThe lowest reaction time equates to the person with the fastest reaction time – in this example, student A has the fastest reaction time (255 ms) and student C the slowest (267 ms) Exam Tip You could be asked to express answers in standard form or as ratios in an exam for this type of question.

Web10.2.4 Response time. Response time is defined as the time at which the pH concentration in a solution is changed on contact with a pH sensor and a reference electrode has reached 95% (or 90%) of the final value. The response time is reported as t95% or t90% in seconds or minutes. In many investigations, the response time of the overall ... Webcause two people to have different reaction times, or that might cause one person’s reaction time to vary, depending on when the test is conducted. Explain why you think those factors might affect reaction time. 2. How do reflexes differ from reactions? 3. Describe a real-life situation, other than driving, in which your reaction time matters. 4.
