Physics of Rifle Recoil :: physics recoil gun guns

Missing figuresRecoil, commonly referred to as kick, occurs as a result of Physical properties at work. However, it is often undesirable because it can be uncomfortable for the shooter and can reduce accuracy. The purpose of this webpage is to discuss the physical science involved with rifle recoil in order to address discordant methods of minimizing it.Rifle recoil is most simply explained by Newtons First and sustain Laws of Motion. When a rifle is pink-slipped, a thrust is exerted on the bullet that projects it forward. By Newtons 1st Law, it can be inferred that and opposite mogul will be imposed on the rifle. From Newtons 2nd Law it can be deduced that this squelch can cause an acceleration (linear or angular) which results in velocity and therefrom kinetic energy. Energy is also transferred into the marksman in the form of work. The summate of this energy is called Recoil Energy and can be calculated. When a crap-shooter is being held at rest, there are three ram downs acting on it. The weight of the gun pushes downward, and the shooters hands exert a recipe force upward on the gun as shown in Figure 2 below. The point P represents the point of contact between the stalk and the marksmans shoulder. pic - Torque 2Figure 2When the gun is fired, the bullet is projected forward by a force, and an opposite force (F) pushes backward on the gun. Since the barrel where the force is acting is slightly above the point of contact with the shooters shoulder, torque is created. The normal forces put on the gun by the shooters hands momentarily run low negligible.* The forces acting on the gun directly after the gun is fired can be simplified as in Figure 3. R is the perpendicular distance between the recoil force and the point P. L is the perpendicular distance between the location of the force due to solemness and the point P. The resulting linear and angular acceleration can be seen in Figure 4.Image - TorqueFigure 3Image - Torque 3Figure 4The rise caused by the angular acceleration can decrease accuracy by altering the trajectory of the bullet, and the horizontal acceleration causes a force to be exerted on the shooters shoulder which can be painful.*This suggestion is not all accurate because the shooters grip will put a downward force on the gun when the gun is fired.
