I'm reading Overview of pediatric injury prevention: Epidemiology; history; application on UpToDate. It says:
The Haddon Injury Control Model, proposes that all injuries are attributable to five forms of energy (kinetic, chemical, thermal, electrical, and radiation).
A knife wound, or a puncture from an ingested foreign body, doesn't have much mass or velocity, which means it has a very low kinetic energy. But they are even worse fits for the other four forms of energy!
Similarly, drowning, strangulation, smothering, and suffocation also do not seem to fit.
How should I classify these low-energy types of injury?
