Angle of Impact Calculator

Formula

The formula to calculate the Angle of Impact is:

\[ \text{AoI} = \arcsin \left( \frac{W}{L} \right) \]

Where:

\( \text{AoI} \) is the Angle of Impact (degrees)
\( W \) is the Width of the Blood Droplet
\( L \) is the Length of the Blood Splatter

What is Angle of Impact?

An angle of impact is a term most often used in forensics to describe the angle at which a droplet of blood has struck a surface. While the most common use is in forensics, an angle of impact can be used to describe an object that has motion that strikes a surface.

Example Calculation

Let's assume the following values:

Width of Blood Droplet (W) = 2.5 mm
Length of Blood Splatter (L) = 5.0 mm

Using the formula to calculate the Angle of Impact:

\[ \text{AoI} = \arcsin \left( \frac{2.5}{5.0} \right) = \arcsin (0.5) \approx 30^\circ \]

The Angle of Impact is approximately 30 degrees.
