A
Introduction to Reaction Time
Read the following explanation carefully before attempting the questions.
1.
Reaction time is the interval between the presentation of a stimulus and the initiation of the response. It is an important factor in braking distances for vehicles and safety responses in various situations. Understanding reaction time helps in designing safer systems and assessing human performance.
[2 marks]B
Concept Review
Answer the following questions to test your understanding of reaction time concepts.
1.
Define reaction time in the context of physics and human responses.
[2 marks]2.
List two factors that can influence a person's reaction time.
[2 marks]C
Calculations Involving Reaction Time
Solve the following numerical problems related to reaction time and braking distance.
1.
A car is travelling at 20 m/s. The driver’s reaction time is 0.25 seconds. Calculate the distance travelled during the driver’s reaction time. Use the formula: Distance = Speed x Time. Provide your answer in metres.
[3 marks]2.
If the reaction time increases to 0.4 seconds at the same speed, what is the new reaction distance? Show your working.
[3 marks]D
Practical Skills & Experimental Design
Answer the following questions about designing experiments to measure reaction time.
1.
Describe a simple experiment to measure human reaction time using a ruler or metre stick. Include the variables you would control, the variables you would measure, and safety precautions.
[6 marks]E
Data Analysis & Interpretation
Read the following scenario and answer the questions based on the data provided.
1.
A group of students recorded their reaction times in a driving simulation. The recorded times (in seconds) were: 0.19, 0.22, 0.20, 0.24, 0.21. Calculate the average reaction time and discuss how variability in reaction times can affect braking distances.
[6 marks]F
Exam-Style Questions
Answer the following structured questions:
1.
Explain how reaction time impacts the stopping distance of a vehicle. Include the roles of driver alertness and vehicle speed in your answer. (6 marks)
[6 marks]2.
A driver’s reaction time is 0.3 seconds. If the vehicle is travelling at 25 m/s, what is the reaction distance? Show all working.
[4 marks]G
Real-World Applications
Consider how reaction time is important in everyday life and industry.
1.
Describe two real-world situations where reaction time is critical for safety or efficiency, and explain why.
