Does the earth spin have any effect on a sniper shot ?

Question

very very long shot .. like the one in a movie called Shooter.
in the movie he said it may have a little effect ..

i wanna know if that is true ..

Answer 1

Vincent G is on the right track. The Coriolis force is an effect of the earth's rotation, and it causes all horizontally-moving objects to feel a slight push toward the right (in the northern hemisphere. The push is to the left if you're in the southern hemisphere).

Contrary to what Vincent says, it works whether the object is moving north, south, east or west.

Extrapolating from equations on Wikipedia, I get the following equation for the sideways deflection of an object due to the Coriolis force:

deflection = (ω•sinφ•x²)/v

where:
ω = earth's angular velocity;
φ = your latititude;
x = distance the object (bullet) travels forward;
v = object's velocity

If you plug in some values, say φ = 40 degrees, and bullet travels 1000 yards, at a speed of 1000 yards per second, you get a deflection of about 4.5 centimeters (about 2 inches) to the right.

Very long-range bullets (like the ones shot from battleships) definitely need to adjust for the effect, or the bullets will land to the right of the target.

Answer 2

you probable won't discover any snipers at here... you're extra probably to in my view understand a expert soccer participant than a armed forces sniper. even nonetheless, in case you would be able to provide the load of the bullet (no longer the whole around) and the value, i'm confident the individuals interior the physics area can assist you to out. keep in mind that no longer all rounds fired from a .50 cal could be the comparable, there are various diverse varieties designed for various issues. OR extra useful yet, look up each and every of the formulation and attempt it out your self... no longer the capturing, basically the formulation.

Answer 3

Not at the range a rifle would have.

The Earth's rotation would have an effect through the Coriolis force, which will be noticeable only if the projectile reaches very high altitude, and then only for the component of the speed that is aligned North-South.

Practically, to feel the influence of Coriolis, you'd have to reach an altitude that takes you out of the atmosphere.

When was the last time real scientists were hired by Hollywood to ensure the movies were authentic?

Answer 4

The bullet will be unaffected by the earths rotation because the bullet at rest is traveling at the same speed and direction as the earths spin, as is the target. Both target and bullet are traveling at the same relative velocity as the earth

Answer 5

no because the target, bullet and the sniper is moving relative to the earth's spinning.

you could look at it this way, the earth is not spinning while the rest of the universe revolves around earth

Answer 6

I really dont think so. The velocity of the bullet is faster than the speed of the rotation of the earth.

Answer 7

No it's the wind, humidit, you name it the earth's rotation has nothing to do with it.

Answer 8

Why would it, if everything is
moving at the same rotation speed.
