Force of Impact

Topic Progress:
  • Force of Impact

    The Force of Impact is the force with which a moving vehicle collides with an object or other moving objects.

    Affected by the Kinetic Energy of the vehicles involved in the collision.
    Distance travelled after the initial impact between them until the vehicle/s come to a complete stop.
    Weight of the vehicle/s involved in the collision
    Speed at which the vehicle/s were traveling

  • Force of Impact

    Diminishing the Consequences
    When you are about to be in a collision you should:
    Reduce your speed

    Head-On Collision
    Accident with two carsIf two vehicles of equal weight traveling in opposite directions at equal speed collide, their force of impact will be equal to that of the two speeds combined
    50km/h going east collides with 50km/h going west is equal to a vehicle going 100km/h and running into a solid barrier
    If one vehicle is larger or moving faster than the other, the smaller, slower moving vehicle will receive more damage.



    Avoid a head-on collision at all costs.
    Steer to Avoid Oncoming Traffic Steer to the right, and avoid hitting another vehicle
    Steer Toward Objects That Will Absorb on Impact Aim towards a “softer” object rather than a “harder” one.

    Hit Something Moving In The Same Direction As You
    The Kinetic Energy involved will be the difference in speed between the two vehicles

    Hit A Stationary Object Rather Than An Oncoming Object
    A stationary object has zero kinetic energy and will absorb some of the force, increasing your chance of avoiding injury

    Hit a Stationary Object With A Glancing Blow
    Deflecting the crash will diminish the force of impact on your vehicle and increases your chance of avoiding injury.

    Choose Where You Are Hit
    Accelerate or brake so that a side-impact collision occurs with the front or rear of your vehicle, thus protecting the passenger compartment.
