Card 1 of 20
Reaction time is the time between [ ].
A
- Water reduces tyre-road friction.
- Smaller braking force increases braking distance.
B
F=ΔpΔtF=\dfrac{\Delta p}{\Delta t}F=ΔtΔp, so a smaller Δt\Delta tΔt gives a larger force.
C
Smaller braking force causes smaller deceleration.
D
Reaction time is the time between detecting a stimulus and beginning a response.
