What is cavitation? A phenomenon in which speed causes a bullet
to generate pressure waves, which cause
damage distant from the bullet's path.
What is Newton's first An object at rest stays at rest and an object in
law? motion stays in motion with the same speed
and in the same direction unless acted upon by
an unbalanced force.
What is potential The product of mass (weight), force of gravity
energy? (acceleration), and height.
- Energy that
is stored. PE
,= mgh
, What is kinetic energy? The energy of motion or movement
KE = ½ mass x velocity^2 or KE = ½ mv^2
What is a vehicle collision? i. Damage to the car does not directly
affect patient care but does provide
information about the severity of the
collision.
ii. By assessing the vehicle that has crashed, you
can often determine the MOI.
What is a human collision? - Kinetic energy produced by the passenger's
mass and velocity is converted into the work
of stopping his or her body.
- Common passenger injuries include lower
extremity fractures, rib fractures, and head
trauma.
What is an internal collision? i. Internal injuries may not be as obvious as
external injuries, but they are often the most life
threatening.
What do we assume with the Assume major injury because the force was
