Question

multiple choice 10 points
how does speed compare to reaction time?
speed is the ability to change course quickly whereas reaction time combines pace and strength.
speed is how quickly someone responds to a stimulus and reaction time is how quickly someone moves.
speed combines pace and strength whereas reaction time is the ability to change course quickly.
speed is how quickly someone moves, and reaction time is how quickly someone responds to a stimulus.

Explanation:

• Option 1: Speed is not about changing course quickly. Agility is related to changing course. And reaction time is not about combining pace and strength.
• Option 2: The definitions are reversed. Speed is about how quickly one moves, and reaction time is about responding to a stimulus.
• Option 3: Speed is not about combining pace and strength (that might be related to power in some contexts). And reaction time is not about changing course.
• Option 4: Speed is a measure of how quickly an object or a person moves (e.g., distance covered per unit time). Reaction time is the time interval between the presentation of a stimulus and the initiation of a response.

Answer:

D. Speed is how quickly someone moves, and reaction time is how quickly someone responds to a stimulus.
