Blood Spatter Analysis Calculator
Introduction & Importance
Blood spatter analysis is a crucial aspect of forensic science, helping to reconstruct crime scenes and determine the sequence of events. This calculator aids in understanding and interpreting blood spatter patterns.
How to Use This Calculator
- Enter the height of impact in meters.
- Enter the impact speed in meters per second.
- Enter the angle of impact in degrees.
- Click ‘Calculate’.
Formula & Methodology
The calculator uses the following formula to calculate the distance of blood spatter:
D = (V² * sin(2 * A)) / g
Where:
- D is the distance of blood spatter (in meters).
- V is the impact speed (in meters per second).
- A is the angle of impact (in radians).
- g is the acceleration due to gravity (9.81 m/s²).
