    In this video, we look at what is meant by the stopping distance of a vehicle. We explore the idea of thinking distance and braking distance before looking at the factors that affect these.

    I thought that the speed of the vehicle also affects the braking distance since it takes longer for the brakes to slow down the vehicle if it's speed is high.

    • @devsehgal7432
      @devsehgal7432 3 ปีที่แล้ว +2

      It does, as more work needs to be done by the breaks

  • @StepanKuzmenko
    @StepanKuzmenko 6 ปีที่แล้ว +10

    Fun fact: more worn tires actually decrease the stopping distance in dry conditions as more of the thread comes into contact with the pavement, and the car could brake harder without losing grip and skidding.

    • @siyonasingh5421
      @siyonasingh5421 5 ปีที่แล้ว

      Maybe the deceleration would be greater if speed of the vehicle would be greater and hence the distance covered by the car will be more ?

    • @rihana6787
      @rihana6787 3 ปีที่แล้ว +2

      because your car is moving faster the stopping distance is longer as it would take longer for the brakes to actually stop the car.

    surely having a distraction wont increase your reaction time it will decrease it

    • @Freesciencelessons
      @Freesciencelessons  5 ปีที่แล้ว +11

      Decreasing your reaction time means that you are reacting faster (in a shorter time). Distractions have the opposite effect (ie a longer reaction time).
