directionality and angle of impact


Here is some of my blood :) The spot on the paper is at a 90 degree angle, the spot under the paper is at a walking/running angle

The measurement of the 90 degree angle is 7mm long and 7mm wide
the measurement of the other droplet is 5mm long and 6 mm wide


Post smash drop is 9mm wide and 10 mm long

The sin A of 90 degree is
7mm /7mm =1

sin of pre smashed blood is 6mm/5mm=1.2

sin of post smashed is 9mm/10mm=.9

Impact spatter- bloodstain pattern produced when an object makes forceful contact with a source of blood, projecting droplets of blood outward from the source

when you are standing directly up and down, the force of gravity will bring the droplet directly straight down, when you run or walk, the droplets follow the path of gravity. Its like one of the laws of gravity, an object in motion will stay in motion (object in this case being blood), an object at rest will stay at rest (standing perpendicular blood drops)
