Final answer:
Droplet size can predict blood splatter velocity and injury type. Larger droplets tend to travel at lower velocities and produce a spatter pattern with larger droplets. Smaller droplets can travel at higher velocities and create a spatter pattern with smaller droplets.
Step-by-step explanation:
Blood spatter can be influenced by the size of the droplets. Larger droplets tend to travel at lower velocities while smaller droplets can travel at higher velocities. When a droplet of blood impacts a surface, it can create various injury types depending on the velocity. If the droplet travels at a high velocity, it can result in a high-force impact and produce a spatter pattern with smaller droplets. On the other hand, if the droplet travels at a lower velocity, it can create a low-force impact and produce a spatter pattern with larger droplets.
