Thinking, braking and stopping Flashcards
What is the stopping distance?
The total distance travelled during the time it takes for a car to stop in response to some emergency
What is the equation to find stopping distance?
Stopping distance = Thinking distance + Braking distance
What is the thinking distance?
The distance travelled in the time it takes the driver to react (reaction time) in metres (m)
What are factors that affect thinking distance?
The speed of the car
The reaction time of the driver
Intoxication
Tiredness
Distractions like loud music and electronics
Age
Recall the process of applying brakes to a vehicle
Energy is transferred from the car and driver to the brakes.
This energy transfer is from kinetic energy to thermal energy
Factors affecting stopping distance
Speed
Mass
Road condition- e.g icy road
Reaction time
