factors affecting braking distance

• what can braking distance be affected by & explanations

  • road conditions - wet, icy - decreases friction
  • poor condition of the vehicle - brakes, tyres - decreases friction
  • increased mass of car - more work needs to be done to stop the car
• what energy transfers take place when a car applies it's brakes?

  • work done by the friction force between the brakes and the wheel
  • reduces the kinetic energy of the vehicle & the temperature of the brakes increase
• to stop a car in a given distance, if its speed is increased, what must happen to the braking force?

  it needs to be greater
• what happens to the deceleration of a vehicle the greater the braking force? what can this lead to?

  the deceleration is greater, this can lead to overheating and/or loss of control
