Question 1

3 Mechanisms of injury

Answer 1

Permanent Cavity
Temporary Cavity
Pressure Wave

Question 2

what is the permanent cavity

slower moving bullets

Answer 2

When the bullet enters the skin it takes that piece of flesh from the beginning and carries it through - sometimes all the way out of the body

Question 3

temporary cavity is when

tissue moving and then the pressure wave blows out hollow organs

Question 5

Mass is the

Answer 5

size of the bullet (weight and caliber)

Question 6

Velocity is determined by..

Answer 6

Gunpowder in the bullet
