According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.
Power factor (PF) in practical shooting competitions refers to a ranking system used to reward cartridges with more recoil. Power factor is a measure of the momentum of the bullet (scaled product of the bullet's mass and velocity), which to some degree reflects the recoil impulse from the firearm onto the shooter (see section on limitations).
The nature of the recoil process is determined by the force of the expanding gases in the barrel upon the gun (recoil force), which is equal and opposite to the force upon the ejecta. It is also determined by the counter-recoil force applied to the gun (e.g. an operator's hand or shoulder, or a mount).
If the shot mass is 10 kg and its velocity is 1000 m/s, the force generated by the shot on the side of the barrel, as it tries to follow this curvature, will be 10,000 N. Figure 10: Typical transverse forces on a shot front band. Thus, transverse forces generated between the shot and the barrel may be very large.
With eleventh hour guidance from the state, Maine gun retailers on Friday began requiring a three-day wait period for gun purchases under one of the new safety laws adopted following the state’s ...
Deciding whether the gunfire at Crown Center qualifies as a mass shooting depends on what definition you use. Here are a few definitions from different organizations, compared with the facts of ...
On October 1, 2015, after a gunman shot and killed his professor and eight students at Umpqua Community College in Oregon, President Barack Obama, who three years earlier, following the massacre ...
Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy (E t) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f) for non-SI units of measure.
