Momentum is transferred from the first object to the second object. In this case, if a gun exerts a force on a bullet when firing it forward then the bullet will exert an equal force in the opposite direction on the gun causing it to move backwards or recoil.

When jumping from a significant height, it is advantageous to land with knees bent because it increases the time taken by person to come to stop, decreases the impact, and hurts less.

When you jump from an elevated position you usually bend your knees upon reaching the ground. By doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing.

So the momentum of the bullet plus gun should be conserved. Although the bullet’s mass is small, its speed is quite large, so it released with large momentum. The gun has much larger mass, so the recoil speed is much smaller, but still large enough to give a serious kick against the shooter’s shoulder.

Recoil: A shorter barrel usually means more recoil, as the blast created when the bullet exits the barrel is closer to the rest of the gun, and thus, closer to the shooter. Usually, the longer the barrel, the higher the muzzle velocity. This is because the bullet has more time to accelerate in a longer barrel.

You mean cartridge, putting it in backwards is not possible, it will not chamber and therefore not fire. You really do mean bullet, ie the projectile, bullets have no powder or primer and therefore the striker will strike the bullet and nothing else will happen.

The absolute answer is yes, any cartridge can be set off by throwing it, IF you can throw like a big-league baseball pitcher AND if it happens to land just right against some object small enough to protrude into the primer pocket, like a sharp pebble.

No, you should never fire a gun underwater. There are some pretty common things that happen to guns underwater. Water causes issues with the ammunition, the action, and the projectile ballistics. Once you get your gun underwater, the barrel almost immediately fills up with water.

velocity) so the much denser water causes the bullet to decelerate much faster than does the “drag” the bullet experiences traveling through the air. You are quite unlikely to be killed by a bullet while underwater.

“It is extremely, painfully loud to fire a Glock underwater. I fired the Glock once underwater. It was very painful for me shooting the gun and the people that were with us a good distance away felt like the gun went off in their ear,” he says. “You have to understand that water is not compressible like air.”

If you’re wondering how it’s even possible to shoot a gun underwater, gunpowder contains oxygen — a key element in the firing process — the gun still goes off exactly as it would on land.

Typical bullets can travel just a few feet through the water before they’re slowed to a stop. CAV-X bullets can reportedly travel 60 meters underwater, and can go through 2 centimeters of steel fired from 17 meters away, indicating that it could even be used to penetrate submarines.

The truth is, car doors do not offer protection against bullets. Glass windows may or may not shatter immediately, but will weaken enough that subsequent bullets fired will most likely get through.

3/4″ plywood isn’t going to stop any bullet that’s likely to be fired at your home in a drive by shooting. 3/4″ plywood isn’t going to stop any bullet that’s likely to be fired at your home in a drive by shooting. It will probably absorb birdshot well enough.

When it is shot underwater, the story is quite different. The bullet was launched only four feet. The denser water is the cause of such a decline in power. While a gun does shoot and looks pretty cool underwater, do not try this at home.

1 Underwater Defense Gun helped combat swimmers defend themselves beneath the waves. The weapon was relatively simple and even has a safety switch that just reads “on” and “off.” The pistol functioned in the same manner as a normal revolver, according to SEAL-UDT expert Kevin Dockery’s Special Warfare Special Weapons.

It is not designed to fire underwater. It needs to be kept dry at the barrel and bolt end to be able to fire.

Enter names like the SPP-11 or the HK P-11 and no, they’re not a spear guns. These hush-hush handguns are true underwater firearms—percussion weapons specifically designed to fire deadly projectiles and take out opponents while submerged under water.

Yes! They can. Glocks can fire underwater relatively easily given the circumstances. So long as the rounds are intact they will still fire.

A spear gun is an one-and-done kind of thing. If you’re hit in a vital area, it can definitely be fatal.
