The quantity of damages sustained in a website traffic collision is determined by the power your auto has in ~ the minute of impact, and the power of the thing you hit. It is essential to understand the pressures at work in collisions, as there is generally some activity a driver deserve to take to minimize the severity that a crash, if one is imminent.

You are watching: What is more important in determining the amount of damage an object sustains in a collision?


Remember that your car must lose all that is kinetic power to concerned a finish stop. In a normal driving situation, gradual braking and slowing will allow time because that this energy to be soaked up by the brakes. In one emergency once a moving automobile comes to a sudden stop, that is kinetic power must dissipate instantaneously. If you protect against suddenly through colliding with another vehicle or object, the amount of kinetic energy your auto has left in ~ that moment will determine the pressure of the impact. The greater the energy, the higher the severity the the crash.

The two determinants which identify the power of a moving vehicle are its weight (or an ext specifically, that is mass) and also the speed at which it is traveling. In straightforward terms, one object’s kinetic power is same to fifty percent its mass multiply by the square the its speed. Heavier objects have much more energy yet in regards to crash severity, speed has actually a lot an ext to answer for.

The pressure of a collision

The force and subsequent severity of any kind of collision count on the power your auto has in ~ the moment of impact, and the power held through the object you collide with. Newton’s 2nd law claims that any object girlfriend hit will certainly exert force ago onto your auto – also if it is stationary. As every activity results in one equal and opposite reaction, your rate at the allude of influence (and the weight of the object you hit) will determine how much force it exerts on her car. Things light enough to move when you hit it will absorb few of your kinetic energy, for this reason limiting the severity the the collision.

So, if friend hit a an extremely light thing such together a trash can or a website traffic cone, the vehicle’s pressure will much outweigh the of the object and also the damage your auto sustains have to be minimal. In all likelihood, a trash deserve to would simply bounce turn off your auto leaving little more than a dent in the wake. Colliding v a heavier stationary thing such as a parked automobile or a lamp short article would it is in a an extremely different story. If your pressure on influence is not enough to relocate the object, the force it sends ago at your automobile will be significant and could do a great deal the damage.

Colliding with other vehicles

The total force of affect (FOI) in a collision in between two vehicles is affected by the direction both cars are traveling in and also the allude at which they connect. If both vehicles are relocating toward every other, their an unified kinetic energy will contribute to the FOI and result in a much more severe collision. This is why head-on collisions space so dangerous and frequently an outcome in loss of life or major injury.

When two cars collide head-on, the car with much less kinetic energy will take it the many damage. This means a slower auto will it is in affected an ext than a much faster car, and a lighter car will be affected much more than a more heavier car. As soon as there is a significant disparity in between the weight and/or rate of 2 colliding vehicles (for instance, once an articulated truck access time a tiny passenger vehicle) the lighter vehicle may be thrown behind or totally crushed.

Traffic collision severity

Let’s look in ~ how pressure affects impact severity in different species of collisions.

Head-on collisions

Head-on collisions constantly produce the greatest force on impact. If you room traveling at 40mph and collide head-on with another vehicle likewise traveling at 40mph, the force of the influence will be equivalent to hitting a brick wall.

Side-on collisions

Side-impact collisions (also known as T-bone collisions) room the second most severe kind of collision. Together the two colliding vehicles room not moving directly toward every other, few of the FOI is decreased by front motion.

Sideswipe

Collisions where 2 vehicles hit each various other in a side-on, sideswipe movement are among the the very least severe. If you finish up in a situation where you cannot stop a crash, you need to steer evasively to aim because that a sideswipe fairly than a T-bone or head-on collision.

Rear-end collisions

Rear-end collisions tend to have the the very least FOI. The force of the rear auto is transferred into the front vehicle upon impact, using up kinetic power by moving it forward.

Minimizing the force of impact

There is nearly always miscellaneous that can be excellent to minimization the force of affect when a collision is unavoidable. You might only have a couple of seconds to evaluate the situation and also react, but this need to be plenty of time if you continue to be calm and remember your driver’s training. Right here are part severity-reducing methods which can aid you to prevent serious injury in the event of an imminent collision:

Hit something softer.If friend cannot slow down in time to stop a collision altogether, friend may be able to redirect your auto towards an object that will an outcome in less damage. Select bushes, crash barriers and sand barrels end concrete barriers, buildings and also other vehicles.

Hit side-on rather than head-on.If you are on track for a head-on collision with an additional vehicle, consider whether you have the right to lessen the severity of the incident by steering come hit one more vehicle side-on instead.

Vehicle safety and security systems

Today’s cars are designed v safety attributes to aid lessen the severity the collisions and improve the vehicle’s in its entirety performance. Few of these functions – such together seat belts – are existing in all vehicles, vice versa, other much more advanced functions are only accessible in certain makes and models. Girlfriend should know these features and how lock work, in situation you should ever drive a automobile that utilizes them. This details will additionally be valuable when girlfriend come to picking a auto for yourself.

ABS, ESP and also traction control

It is quite typical for modern vehicles come include electronic safety systems which aid to keep optimal balance and improve traction.

Traction control systems.Traction manage systems use sensors ~ above the vehicle’s wheel to detect once one or more wheels have lost traction and also are rotating much faster than the others. The mechanism then automatically applies the brakes on the wheel, to sluggish it down till it regains traction.

Electronic security programs (ESP)Electronic stability programs or active steering control systems space designed to minimization understeering and oversteering. This clever solution compare the motion of the steering wheel v the really course and trajectory the the car. If it detects a disparity in between the two, the mechanism will strategically apply the brakes to assist the driver remain in regulate of the vehicle.

There is no doubt that electronic safety systems can make it far less complicated to control a car in negative driving conditions or during an emergency. However, as with the mechanical contents of her car, these safety and security systems space susceptible to malfunctioning. All vehicle drivers must know how to maximize traction, restore balance and also prevent understeer or oversteer without the aid of these equipment as they might one day be compelled to cope without them.

Seat belts

No matter how many high-tech automobile safety solution are emerged in the future, none will certainly ever have the ability to reduce death and also injury as successfully as the simple seat belt. This is the car’s ultimate security feature, and yet, so numerous motorists disregard to buckle up before driving. Wearing her seat belt is the solitary most effective method to remain in control during emergency maneuvers and also protect yourself during a collision.

If you space not put on a chair belt, executing evasive maneuvers can throw friend from the driver’s seat, making the harder to reach the steering wheel and pedals. Her seat belt will likewise ensure you are in a safe position if an affect causes the airbag to deploy. Without the chair belt holding you in place, the force of a deploying airbag could reason serious injury.

Know your owner’s manual

Most vehicle drivers have little an ext than a short flick with their vehicle owner’s manual before tossing it right into the glove compartment or on come the ago seat. Familiarizing yourself through the materials of your owner’s hands-on is imperative, as it includes invaluable information around the vehicle’s safety features and electronic equipment which could one day save your life in an emergency. Something you must know around in-car adjustments, tire pressure and also alignment, weight distribution and also dashboard controls will be comprehensive in this publication – make sure you examine it thoroughly!
