We have all seen bullets being shot in movies. Some may have seen it in real life too. Unless the scene is shown in slow motion we cannot see the bullets traveling with our naked eye. All we know is that it travels at tremendous speeds. Though there have been scenes in movies where some people dodge the bullet after seeing it being fired, it is virtually impossible to dodge a bullet at the speed with which it is traveling.
So, how fast do bullets travel? Has anyone measured the speed? Do all bullets travel at the same speed? These are all questions all of you will certainly like to be answered. However, before we check the speed of the bullet let us see some other facts. What are bullets made of? How are they made?
Anatomy Of A Bullet
The bullets are constructed somewhat like the firecrackers. There are three parts in most of the bullets. The parts are the primer, the propellant and the metal bullet itself.
The primer acts as a fuse. When the trigger of a gun is pulled, the spring mechanism in the gun pushes a firing pin into the back of the bullet. This will ignite the explosive which is inside the primer. There is another explosive inside the propellant. This is ignited by the ignition in the primer. The explosive inside the propellant is what builds the pressure to push the bullet out of the gun. This pressure is what decides how fast do bullets travel.
When the pressure is built up fully the bullet is pushed out of the gun. The main explosive takes up two-thirds of the volume of the bullet. The bullet travels down the barrel of the gun and shoots into the air. When the bullet escapes the gun, the pressure of the explosion which happened inside comes out giving out what is known as the gunfire sound.
Speed And Path Of Bullet
So, how fast do bullets travel? The bullet emerges out of the gun with such a force that it travels at great speed. Most bullets travel at a speed of over 1800 miles per hour. This is more than the speed of light. Mostly the bullets travel in a straight line. But several forces are acting on it which makes the path not so straight after some distance.
The inside of the barrel is grooved spirally so the bullet when it comes out is spinning at high speeds. This gives it the ability to travel up to a distance in a straight path.
