inertia
|
tendency of an object to remain at rest or remain in motion unless acted upon by an external force.
|
|
kinetic energy
|
the energy an object has while it is in motion. It is related to the object’s
mass and velocity. |
|

|
crumple zone
|
the region of a vehicle designed to absorb the energy of impact.
|

pressure wave
|
area of overpressure that radiates outward from an explosion.
|
|
oxidizer
|
an agent that enhances combustion of a fuel.
|
|
blast wind

the air movement caused as the heated and pressurized products of an explosion move outward.
|
|
crush syndrome
|
systemic disorder of severe metabolic disturbances resulting from the
crush of a limb or other body part. |

chemicals released by white blood cells that attract more white blood cells to an area of inflammation.
|
|
overpressure
|
a rapid increase and then decrease in atmospheric pressure created by an
explosion. |

complete displacement of a bone end from its position in a joint capsule.
|
|
transverse fracture
|
a break that runs across a bone perpendicular to the bone’s
orientation. |
|
oblique fracture
|
break in a bone running across it at an angle other than 90 degrees.

|
comminuted fracture
|
fracture in which a bone is broken into several pieces.
