Projected impact stains are what?

Explanation:
Projected impact stains occur when a source of blood is struck or otherwise forced, causing the blood to be dispersed into droplets that travel away from the origin. The defining feature is dispersion by an external force, producing spatter that emanates from a point or area where the blood originated. This contrasts with gravity-driven flows, which simply move downward under gravity, and with transfer stains, which result from direct contact between two surfaces. The pattern often shows droplets of various sizes radiating outward from the source, allowing investigators to infer the location of the blood source and the direction of travel.
