Braking and Forces

• What factors influence the stopping distance of a vehicle?

  Driver's reaction and braking force effectiveness
• What is the definition of thinking distance?

  Distance traveled during the driver's reaction time
• What is thinking distance directly proportional to?

  Vehicle's speed
• What affects thinking distance?

  Driver's reaction time
• What is braking distance?

  Distance traveled under braking force after brakes are applied
• What factors affect braking distance?

  Speed, road conditions, brake and tire condition
• How does speed affect braking distance?

  Greater speed results in greater stopping distance
• How does thinking distance change with speed?

  Increases linearly with speed
• What is the relationship between speed and kinetic energy?

  Higher speed means more kinetic energy
• What is the formula for braking force?

  $v^2 =$$u^2 +$$2as$
• What does the braking force do when braking?

  Converts kinetic energy into thermal energy
• What happens to the brakes when kinetic energy is converted?

  Temperature of the brakes increases
• What are potential safety concerns related to braking?

  Loss of control and overheating brakes
• What is the equation for force in relation to mass and acceleration?

  $F =$$ma$
• What are the factors influencing reaction time?

  • Tiredness
  • Drugs and alcohol
  • Distractions
• How can reaction time be measured accurately?

  • Use the ruler drop test
  • Perform multiple tests
  • Calculate average reaction time
  • Test under different conditions
• What influences the effectiveness of braking force?

  • Speed of the vehicle
  • Brake condition
  • Road and weather conditions
  • Tire condition
