When will a bullet stop?

A bullet stops when its kinetic energy is dissipated, typically upon impact with a solid object, such as a wall or another surface, or when it embeds itself in a softer material, like flesh. The distance a bullet travels before stopping can vary greatly depending on factors such as the type of ammunition, the angle of fire, and the medium it encounters. In open air, a bullet will eventually lose speed due to air resistance, but this can take considerable distance. Overall, the bullet will stop when it can no longer overcome the forces acting against it.
