5.6.5 Stopping Distances

• The stopping distance is the sum of the thinking distance and the braking distance.
• Braking distance depends on speed, road conditions, and brake condition.

  True
• Match the stopping distance component with its definition:

  Thinking Distance ↔️ Distance traveled during reaction time

  Braking Distance ↔️ Distance traveled while brakes applied
• The braking distance is the distance traveled while the brakes are applied to bring the vehicle to a stop.
• Worn brakes increase braking distance.


  True
• Match the factor affecting thinking distance with its impact:

  Driver alertness ↔️ Reduces thinking distance

  Reaction time ↔️ Increases thinking distance
• Concentration is a factor that reduces thinking distance.
• How do slippery road conditions affect braking distance?

  Increase braking distance
• As speed increases, both thinking distance and braking distance increase.
• Thinking distance is proportional to the speed of the vehicle.


  True
• What is braking distance proportional to?

  Square of speed
• Match the speed with its impact on stopping distance components:

  Low speed ↔️ Short stopping distance

  High speed ↔️ Very long stopping distance
• Thinking distance is proportional to speed.


  True
• Braking distance is proportional to the square of speed.


  True
• Reducing vehicle speed is crucial for minimizing stopping distance
• Match the stopping distance component with its definition:

  Thinking Distance ↔️ The distance travelled during reaction time

  Braking Distance ↔️ The distance travelled while braking
• What are the three main factors affecting braking distance?

  Speed, road conditions, brake condition
• Higher speeds require more distance to stop the vehicle
• Why is braking distance proportional to the square of speed?

  Higher speeds require more force
• Thinking distance is calculated by multiplying speed and reaction time.

  True
• What is the stopping distance of a vehicle defined as?

  Total distance to stop
• What is the thinking distance influenced by?

  Reaction time and alertness
• What is the definition of thinking distance?

  Distance during reaction time
• Order the components of stopping distance in a vehicle.

  1️⃣ Thinking Distance

  2️⃣ Braking Distance

  3️⃣ Stopping Distance
• What are the factors affecting thinking distance?

  Reaction time, alertness, concentration
• Alert drivers have a shorter thinking distance compared to tired drivers.
• What are the factors influencing braking distance?

  Speed, road conditions, brake condition
• What is the definition of braking distance?

  Distance while brakes applied
• Higher speeds require more braking distance.


  True
• What are the two components of stopping distance?

  Thinking distance, braking distance
• What is the formula for stopping distance?

  Stopping distance = Thinking distance + Braking distance
• Steps in calculating stopping distance

  1️⃣ Calculate thinking distance

  2️⃣ Calculate braking distance

  3️⃣ Add thinking distance and braking distance
• The total stopping distance is the sum of thinking distance and braking distance.


  True
• What are the three key factors influencing thinking distance?

  Alertness, concentration, reaction time
• Match the factor affecting thinking distance with its impact:

  Driver alertness ↔️ Reduces thinking distance

  Reaction time ↔️ Increases thinking distance
• Braking distance is calculated using the formula (Speed^2) / (2 × Deceleration).

  True
• As a vehicle's speed increases, both the thinking distance and braking distance become longer
