pysäytysvoima
Pysäytysvoima is a Finnish term referring to stopping power or the effectiveness of an object, weapon, or method to halt a moving target or motion. In common usage it appears in discussions about firearms and ballistic performance, but the concept also appears in physics as the force required to stop a moving body. The term is descriptive rather than a single, standardized measurement.
In firearms and terminal ballistics, pysäytysvoima describes how effectively a projectile can incapacitate or stop a
Measurement and interpretation of pysäytysvoima are subjects of debate. Common indicators include kinetic energy at impact,
From a physics standpoint, stopping force can be described by classical mechanics: F = Δp/Δt and F =
