Mechanisms of Injury
A definition:
The force applied to (or taken from)
the body and how it reacts.
An example:
Mechanisms of Injury
 Remember these laws:
 Newton’s First Law of Motion
 An object, whether at rest or in motion, remains in that
state unless acted upon by another force
 Conservation of Energy Law
 Energy can’t be created or destroyed, it can only
change form
 Newton’s Second Law of Motion
 F=M X a or F=M X d
 Kinetic Energy
 KE= ½M X V2
