枪的后座既可以测量,也可以计算。测量和分析结果一般仅能在弹道实验室进行。但是,任何一名能夠求解简单公式的射手,可以计算出准确性很满意的后坐,而且用一台现在非常普遍的袖珍计算机就可以很容易地计算。后坐的基本公式是根据动量守恒定律。从该定律可以知道,枪的后座动量必须等于被推向前的弹头和装药的动量。一个物体的动量是其质量和速度的乘积。后坐的基本公式可以用下列数学方式表示: MgVg=MbVb+McVc式中 Mg,Vg=枪的质量和后座速度 Mb,Vb=弹头的质量和初速 Mc,Vc=发射药的质量和有效排气速度枪的质量、弹头的质量和装药的质量是很
The rear seat of the gun can be measured, can also be calculated. Measurement and analysis results are generally only available at ballistic laboratories. However, any Sagittarius who can solve simple formulas can calculate the recoil with good accuracy and easily calculate it with a pocket computer that is now very common. The basic formula for recoil is based on the law of conservation of momentum. From this law it can be seen that the gun's rear seat momentum must be equal to the momentum of the projectile and charge being pushed forward. The momentum of an object is the product of its mass and speed. The basic formula for recoil can be expressed mathematically as follows: MgVg = MbVb + McVc where Mg, Vg = gun mass and rear seat speed Mb, Vb = mass and muzzle velocity of the warhead Mc, Vc = mass and effective exhaust of the propellant Speed gun quality, warhead quality and charge quality is very good
