Collision & Injury Dynamics

Collision & Injury Dynamics:�The mathematical principles of collision physics are complex and unique for each and every accident. They can be simplified, as many of the forces involved are so small that for practical purposes they are insignificant.� Importantly, these principles often support the position of the patient and their doctor.Car accidents can be devastating! Many people suffer through the agony and pain car accidents cause their bodies and many times they have no idea of what to do. People will go to the emergency room and be prescribed medication and sent home. What the hospital does not realize is that these people are still in pain and many times can�t work for days after their accident. That�s where I come in, I make sure the patient receives a thorough evaluation to determine how much damage was done to them after their collision.� Then I will treat the patient according to what they need so they can get back to the quality of life they enjoyed prior to their car accident.� If you�ve been in a motor vehicle collision and don�t know what to do, please give us a call today at�915-850-0900!� I�ll make sure you get the care you deserve.

Automobile Accidents & Tires: Pressure, Stopping Distance Continued

Automobile Accidents & Tires: Pressure, Stopping Distance Continued

In the prior composing we created the foundation of the significance of tire pressures. Specifically, we demonstrated that a third of the vehicles on the street and additional only a third of those vehicles have an underinflated tire and a warning light, respectively.

We also know a 20% decrease in pressure results in substandard performance, these are the factors we’re likely to explore.

Underinflated tires have a different profile and contact patch with the road.

Where the tire meets the roadway is known as the contact patch. Maximizing the touch patch affords the motorist the most performance, specifically steering and braking. What happens if we reduce the contact patch? Under inflation does that.

The contact patch is what connects the vehicle to street, when

How do airbags function?

Why do they deploy in some instances and not others?

The module monitors various vehicle systems and contains a threshold for deployment; in simpler terms, this usually means the collision must meet specific settings to deploy an airbag. The idea is exactly the same while the system of every automobile brand is specifically different from the next.

If the collision, as computed by the module, is intense enough, it’ll deploy the appropriate airbag(s). The module has the final say when an airbag is deployed, this is software & hardware dependent.

The module can understand, through onboard accelerometers, changes in the vehicles direction and speed. The module constantly calculates these changes and when it “sees” a switch beyond preset thresholds it begins to track, quite tightly, the fluctuations (this is called algorithm enablement). If it establishes that the changes meet the standards for airbag deployment, it’ll deploy

Transfer of Energy in No Damage Accidents, Causing Injury

Transfer of Energy in No Damage Accidents, Causing Injury

In the last two writings we explored how low speed collisions can have substantial energy transfers with minimal (if any) damage. Here we will discuss the myth of “no damage = no injury” from a vehicle appearance / design point of view and how it relates to injury in a collision.

So as to get into this subject, we need a little history lesson first. With vehicle style being the topic of focus, the industry exploded after World War II. The jet age influenced bumpers, headlights and taillight’s fins. Something else happened too, for the first time in the automobile’s history, vehicles were more than “around town” horse-less buggies; the power of their engines and speeds potential dawned a whole new arena — security. In the 1960’s vehicle aesthetics began to compromise with safety. Automotive designers started to consider topics like; occupant restraints structural integrity, and crash worthiness.

The industry faced slow growth and change into the 1980’s, each revision or change di

In the prior writing we explored the criteria for vehicle integrity. In this writing we’ll expand on conservation of momentum. You’re encouraged to do so when you haven’t read the previous article.

Expanding on Conservation of Momentum

Remember we previously said, “The momentum moving into a collision could be accounted for at the outcome” when we discussed the concept of conservation of momentum. Here we will introduce the formula and walk through its parts; we have to comprehend this in order to explore each other influence.

The full formula:

Let�s walk through this, on the left side of the equation we have which is the weight of the first vehicle before the collision multiplied by which is the velocity (in feet per second) of the first vehicle before the collision. is the weight of the second vehicle before the collision times which is the velocity (in feet per second) of the second vehicle before the collision. On the right side of the equation we have which is

Where Does the Energy Go in Low Speed Auto Accidents?

There are many factors that play a role in the dynamics of collisions. These include vehicle design and type, speeds, angles of approach, kinetic & potential energy, momentum, acceleration factor, friction… the list is quite long. There are a few constants in which we are curious. These constants are the building blocks of the planet and they make the world of collisions quantifiable and predictable.


Within this two-part series we will explore the factors which have the most influence in low speed collisions and how these factors are associated with injury. Note: nothing about these writings is inclusive, there is too much material to explore in depth. The objective of these writings is to present the concepts.

Conservation of Momentum & Auto Accidents

In this writing the subject of exploration is conservation of momentum and how it relates to low speed collisions and bodily injury of the occupant. Conservation of momentum is built on Sir Isaac Newton’
