Stopping Distance Flashcards
1
Q
How do you calculate stopping distance?
A
Thinking distance + Braking distance
2
Q
What is thinking distance?
A
Distance car travels in time it takes driver to apply brakes.
3
Q
What is braking distance?
A
Distance travelled after driver applied brakes.
4
Q
What is reaction time affected by?
A
- Tiredness
- Drugs
- Alcohol
- Distractions
5
Q
What is braking distance affected by?
A
- Poor road and weather conditions (wet, icy)
- Poor vehicle conditions
6
Q
What causes a car to slow down ?
A
- Friction between brakes and wheel convert kinetic energy into heat, slowing vehicle down.
7
Q
If an object moves faster, how does that affect braking distance?
A
- Deceleration is bigger.
- Brakes can overheat.
- Driver lose control
- Braking distance increase
8
Q
How do you calculate thinking distance?
A
Speed x reaction time
9
Q
How do you calculate braking distance?
A
½ x speed x time to stop
