If they want to hit their targets, snipers can move into a position that doesn’t reveal themselves, their target, wind, humidity, temperature, barometric pressure, gravity, and even world turn They have to consider many variables that can affect the flight of a projectile, such as

Yes, you read that right: Snipers; before they hit their target, the rotation of the earth depends on the bullet they will fire. what effect it will exert in the air They also have to count.

This is called the Coriolis effect, and it’s something snipers should pay close attention to when shooting.

Coriolis force formula

Named after the French mathematician and engineer Gaspard-Gustave de Coriolis in 1835. Coriolis effectaround its axis The earth rotates from west to east It is characterized as a form of inertial force due to rotational motion. Because of this force, any object moving on or near the Earth’s surface must deviate slightly from its orbit due to the rotation of the planet.

The direction and magnitude of the deviation depend on two factors: the latitude And speed of the object. Coriolis effect, latitude 90 degrees near the poles is biggerlatitude 0 degrees zero at the equator fall. This effect is also directly proportional to the speed of the object. The faster the object moves, the greater the deflection.

This annoying situation also causes objects moving in a straight line to deviate from their route in different ways depending on which hemisphere they are in. For example in the northern hemisphere objects in the direction they are aiming to the right; in the southern hemisphere while on your left they turn right.

So how does this Coriolis power affect snipers?

In short, since bullets are also objects that move on our Earth, the Coriolis effect occurs when flying in the air. focused causing them to deviate from their jobs. The longer the flight distance and duration of a bullet, the more pronounced the deviation becomes.

Suppose a sniper at 51.5 degrees latitude wants to hit a target 914 meters away with a projectile flying at 500 km/h. When the Coriolis effect is calculated, this bullet is due to the rotation of the Earth. will deviate approximately 7.5 centimeters to the right. In addition, since gravity pulls the projectile down as it flies, the sniper will have to aim higher or lower depending on whether he is facing east or west.

To give another example, a projectile fired from a distance of 1000 meters in a northerly direction at 45 degrees latitude will be approximately where it would normally impact due to the Coriolis force. Hits 1 inch to the right. If the same bullet is fired in an easterly direction, it will hit about three inches lower than expected.

As you can see, the Coriolis force also affects the vertical component of a bullet’s trajectory due to gravity. fall more or less than expected why would it be. This is because as a projectile travels long distances, it either approaches or moves away from the Earth’s center of mass, changing its potential energy and therefore its kinetic energy.

(This effect is known as the Eötvös effect, named after the Hungarian physicist Loránd Eötvös who worked on it in 1908. The Eötvös effect is the opposite of the horizontal component of the Coriolis force: it causes a projectile headed toward the east is fired falls less than expected , and a projectile fired west to fall more than expected. But that’s the subject of another article…)

How do snipers explain the Coriolis force before firing?

Snipers must consider both components of the Coriolis force when aiming at long ranges or high latitudes. This muzzle velocity, bullet weight, drag coefficient, wind speed and direction, air density and temperature, elevation angle, latitude and azimuth (angle between north and firing direction) using ballistics tables or calculators that take into account various factors such as

Even some modern rifles use these factors. can calculate automatically It even has built-in systems. These tools help snipers estimate how much they need to adjust their aim point to compensate for Coriolis force and other effects.

If you like games, this is one game that you are sure to come across and love. On a Call of Duty missione is also explained. In ‘All Ghilled Up’, where we play the young Captain Price and kill Captain MacMillan and Zakhaev with a sniper rifle, we are asked to consider the Coriolis effect.

Understanding how the Coriolis Effect affects snipers helps us understand how specialized this is. Although we have explained this physical phenomenon through snipers, we have It also sheds light on our world. Thanks to the Coriolis force formula, we can also calculate hurricanes, ocean currents and weather conditions.
