Module 11.1

Question 1

Blunt force trauma

Answer 1

Blunt mechanical forces-non-penetrating, hitting, punching, kicking, etc.
Chop wounds-blunt and sharp

Question 2

Force

Answer 2

Push or pull resulting from interaction with another object
Only exist as a result of interaction
F=m*a
3 types of PURE forces: compressive (pressing/squeezing), tension (pulling apart), shear (sliding)
Non-axial forces: torsion (twisting), bending (asymmetrical causing bending)
Can combine
Both objects in motion-change in forces and KE
Species, age, health, etc. factor into damage caused

Question 3

Kinetic energy

Answer 3

Energy of motion
Transferred by force: KE=1/2mv^2
Depends on: amnt of force, time, surface area, body region, and weapon
