Mechanism of injury (MOI)
The way in which traumatic injuries occur; it describes the forces (or energy transmission) acting on the body that cause injury.
Energy concepts related to injury
The three main types of energy associated with injury are potential energy, kinetic energy, and the energy of work (excluding thermal energy, which causes burns).
Potential energy
Energy that is stored and has the potential to cause injury when released.
Kinetic energy
The energy of a moving object.
Energy of work
Energy that is transferred when a force acts over a distance.
Law of conservation of energy
Energy can be neither created nor destroyed, but can only be converted or transformed.
Work
Defined as force acting over a distance.
Kinetic energy relationship
Kinetic energy reflects the relationship between the mass (weight) of an object and its velocity (speed).
Kinetic energy formula
Kinetic energy equals one-half the mass times the velocity squared (KE = ½m × v²).
