Study Notes
Stopping Distances
- Stopping distance measures the total distance from when a driver perceives the need to stop until the vehicle comes to a complete halt.
Thinking Distance
- Thinking distance is the range covered from the moment a driver recognizes the need to stop until the brakes are applied.
- Calculated using the formula: Thinking Distance = Speed * Reaction Time.
Braking Distance
- Braking distance refers to the distance a vehicle travels after the brakes are engaged until it stops.
- Calculated with the formula: V² = U² + 2as, where V is final velocity, U is initial velocity, a is acceleration, and s is distance.
Reaction Time
- Reaction time can be determined by: Reaction Time = Thinking Distance / Speed.
Relationship Between Speed and Thinking Distance
- There is a direct proportional relationship between thinking distance and vehicle speed, increasing by 3 meters for every 10 mph increase.
Factors Affecting Thinking Distance
- Various factors can influence thinking distance, including:
- Age
- Tiredness
- Alcohol consumption
- Drug use
- Distractions (e.g., mobile phones, passengers)
Factors Affecting Braking Distance
- Braking distance can be impacted by:
- Road conditions (e.g., rain, fog)
- Tire quality and friction
- Vehicle speed
- Mass of the vehicle
- Quality of the braking system
- Road surface (e.g., gravel vs. asphalt)
- Inclines (hills impact gravitational forces)
