Define MOI (Mechanism of Injury)
What is "kinetics of trauma" and what can it predict?
Trauma is nearly always the result of what?
Define Kinetics
Define kinetic energy:
What two factors does the amount of kinetic energy a moving body has depend on?
Formula for how kinetic energy in a moving body is calculated:
Which is a more significant factor in kinetic energy?
Mass or velocity?
The law of inertia states:
(Sir Isaac Newton)
Define acceleration
Define deceleration
A faster change in speed (acceleration or deceleration) results in:
Energy Changes Form and Direction
Impacts
Vehicle collision
Impacts
Body Collision
Impacts
Organ Collision
The faster a vehicle is traveling the greater the ____ _____, and the higher rate of acceleration or deceleration, the greater the ____. The greater these factors and the greater number of impacts, the greater _____ for injury.
What are common mechanisms of injury?
Motor Vehicle collisions
You should have a high index of suspicion if:
Motor Vehicle collisions
Frontal Impact
A deformed steering wheel indicates possible ___ or ___ injury.
The heart suffers the effect of two forces: ____ and ____.
_____ force occurs when the heart is caught between the sternum and the spine, which can bruise the heart muscle.
The heart is suspended by the aorta, which is attached posteriorly at the arch by a ligament. ____ force tends to pull the aorta at the ligament, which may tear or transect the aorta.
The "paper bag" syndrome results from ____ of the ___ against the steering column.
Impact marks or cracking to the windshield, also know as "___-___" marks indicates possible ____ injury.
Motor Vehicle collisions
Rear-End Impact
If a vehicle does have headrest or they are improperly positioned, the neck is hyperextended and the anterior spinal ligaments are often stretched or torn. This if often referred to as a "_____" injury.
Injuries to be expected include the initial __ injury followed by either the frontal __- and __ or __- and ___ injuries once the vehicle to a complete stop and the occupant jolts forward.
Motor Vehicle collisions
Lateral Impact

Falls
Energy travels in a ____ line until it is forced to curve.
Feet-first Falls
Falls of more than 20 feet
Extending arms to break the fall can result in a fracture of the wrist bones (first point of energy dissipation) known as a ____ or "____ ____".
