Vehicle Brakes and Forces

• What happens when a force is applied to the brakes of a vehicle?

  Work done by friction force reduces kinetic energy
• How does friction force affect the vehicle's kinetic energy?

  It reduces the kinetic energy of the vehicle
• What is the relationship between speed and braking force needed to stop a vehicle?

  Greater speed requires greater braking force to stop
• What happens to the temperature of the brakes when they are applied?

  The temperature of the brakes increases
• What is the effect of greater braking force on vehicle deceleration?

  It results in greater vehicle deceleration
• What can large decelerations lead to in terms of brake performance?

  They may lead to brake overheating and loss of control
• What are the consequences of brake overheating?

  It can lead to loss of control of the vehicle
• What factors influence the braking force required to stop a vehicle?

  • Speed of the vehicle
  • Distance to stop
  • Weight of the vehicle
  • Road conditions
• What are the effects of excessive braking force on a vehicle?

  • Increased deceleration
  • Potential brake overheating
  • Loss of control
  • Possible brake failure
