How fast does a fired bullet reach?



The word 'bullet' is often used when something is done at great speed, such as 'bullet shot' or 'bullet round trip.' However, little is known about how fast a bullet actually travels. LiveScience, a science news media, explains the speed of a bullet fired from a real gun.

The speed of a bullet fired from a gun is affected by internal factors such as the type of propellant that propels the bullet, the weight of the bullet, and the shape and length of the barrel. External factors such as wind, gravity, and the forces exerted on the bullet as it moves through the air also have a significant effect. Furthermore, these factors greatly affect the '

terminal trajectory ,' which describes the behavior of the bullet when it hits the target.

According to forensic scientist Michael Haag, the term 'bullet' refers to only a small portion of a bullet. Bullets (warheads) are usually made of heavy metals such as lead and are encased in brass or copper casings. When you pull the gun's trigger, the firing pin impacts the detonator located at the bottom of the bullet. The detonator then ignites the gunpowder, sending the bullet attached to the front of the cartridge flying forward at tremendous speed.



As the bullet moves toward the muzzle, it experiences friction. 'The longer the gun barrel, the longer the gas that accelerates the bullet has to reach its maximum velocity, which increases the speed at which the bullet leaves the barrel,' said Stephanie Wolcott of Virginia Commonwealth University. It will rise,” he said.

For this reason, the gun that can achieve the highest speed is basically a rifle. Rifles are primarily intended for long-range use. It is said that a bullet fired from a rifle can travel up to about 2 miles (about 3.2 km).

When

a .223 Remington is fired with a rifle, the actual bullet speed reaches a maximum of approximately 4390km/h. According to LiveScience, this speed is enough to cover the distance of about 11 soccer courts in one second. Also, when firing a 9x19mm Parabellum bullet from a handgun, it can reach approximately 2200km/h.



The speed of bullets fired from

the AK-47 , one of the most widely used firearms around the world, reaches approximately 2580 km/h. The AK-47 is capable of firing in full auto mode and can fire up to 600 bullets per minute.

On the other hand, the fired bullet immediately experiences air resistance and begins to decelerate. Also, the bullet travels straight while rotating due to the gyroscopic effect , but soon the bullet no longer flies straight due to the effects of air resistance and gravity.



Mr. Wolcott said, ``All bullets are designed to reduce air resistance as much as possible, and continue to travel straight for a while after being fired.However, after that, they are greatly influenced by gravity and air resistance, and gradually the bullet It will fall towards the ground.'
