All 19 questions on Stopping distances and road safety, as a list

June 2024, Physics Paper 1 Foundation, Q2(a)(i) (1 mark): Which of these is the driver’s reaction time shown in Figure 3? (1) A 0 s B 1 s C 4 s D 22 s
June 2024, Physics Paper 1 Foundation, Q2(a)(ii) (1 mark): State one factor that might increase a driver’s reaction time. (1)
June 2024, Physics Paper 1 Foundation, Q2(a)(iii) (3 marks): Calculate the distance travelled between when the driver applies the brakes and when the car comes to rest in Figure 3. Use the equation distance = area under t
June 2024, Physics Paper 1 Foundation, Q2(b) (2 marks): The stopping distance of a car is the thinking distance plus the braking distance. A car has a device that can detect an obstacle in the road ahead. The device
June 2024, Physics Paper 1 Foundation, Q2(c)(i) (1 mark): State the change in speed that the computer should make when the road is wet. (1)
June 2024, Physics Paper 1 Foundation, Q2(c)(ii) (1 mark): Give a reason why this change in speed is necessary when the road is wet. (1)
June 2023, Physics Paper 1 Higher, Q4(a)(i) (3 marks): Calculate M’s reaction time as a percentage of the time sound takes to travel from L to M. (3) %
June 2022, Physics Paper 1 Higher, Q2(a)(i) (2 marks): The sign tells drivers to drive at a slower speed in wet weather. Explain why it is safer for drivers to drive at a slower speed in wet weather. (2)
June 2022, Physics Paper 1 Higher, Q2(a)(iii) (3 marks): The driver’s reaction time is the time between the driver seeing an emergency and starting to brake. A car is travelling at a speed of 31 m/s. The car travels 4
June 2022, Physics Paper 1 Foundation, Q3(c)(iii) (2 marks): The student had a choice of how to measure the time the trolley takes to roll down the ramp. 1. Use a hand‑held stopwatch. 2. Use light gates at the top and bot
June 2022, Physics Paper 1 Foundation, Q6(a)(i) (2 marks): The sign tells drivers to drive at a slower speed in wet weather. Explain why it is safer for drivers to drive at a slower speed in wet weather. (2)
June 2022, Physics Paper 1 Foundation, Q6(a)(iii) (3 marks): The driver’s reaction time is the time between the driver seeing an emergency and starting to brake. A car is travelling at a speed of 31 m/s. The car travels 4
November 2021, Physics Paper 1 Foundation, Q3(a)(i) (1 mark): The stopping distance for the car would be smaller if the car (1) A had more passengers B had worn tyres C needed new brakes D was travelling more slowly Figure
November 2021, Physics Paper 1 Foundation, Q3(a)(ii) (2 marks): Use the graph to find the driver’s reaction time. (2) reaction time = s
November 2021, Physics Paper 1 Foundation, Q3(b) (2 marks): Figure 5 shows the apparatus a student uses to investigate how the stopping distance of a toy car depends on the type of surface that it is stopping on. toy car
November 2021, Physics Paper 1 Foundation, Q3(c)(i) (1 mark): State the anomalous value of stopping distance given in the table in Figure 6. (1)
November 2021, Physics Paper 1 Foundation, Q3(c)(ii) (2 marks): Use the results in Figure 6 to calculate the average stopping distance. (2) average stopping distance = m
November 2021, Physics Paper 1 Foundation, Q3(c)(iii) (1 mark): State one way the student could increase the speed of the car as it reaches the flat surface. (1)
November 2020, Physics Paper 1 Foundation, Q6(d) (6 marks): Many factors can affect the stopping distance of a car. Some of these factors involve the driver and some of these factors involve the car or the road. Explain
