The grooves in the barrel.
Ballistic spindrift is when the spin imparted on the bullet causes a drift in the direction the TOP of the bullet is spinning in.
What causes it to rotate is the rifling in the barrel. What causes it to continue to rotate after it leaves the barrel is centrifugal force.
There are spiral grooves engraved on the inside of a rilfe or pistol barrel. When a bullet is fired, it is forced into those grooves, which impart a spin to the bullet. The grooves are called rifling.
If you mean literally then a bullet, pole etc.
Grooves in the barrel. That is called rifling.
Assasination of Franz Ferdinad?
The grooves (rifling) cut into the barrel.
Part or parts malfunction. Get to a gun smith.
Yes, it's quite possible to survive from bullet wounds at any time including the 1920's, it all depends what injury the bullet causes, a flesh wound in the arm, leg, buttocks etc. is not usually fatal, if the bullet hits a vital organ such as the heart or brain, causes serious internal injuries or the wound becomes infected then you are in trouble.
I suppose that the causes are the high energy, density and speed.
Hollow Point bullets have a hollow nose or an hole in the nose of the bullet. This causes the bullet to mushroom into a larger diameter when it hits something. A regular bullet is conical or blunt nose in shape. Some can be pure lead or can be jacketed with a bronze or copper coating.
When the bullet penetrates into an object its velocity decreases very much or becomes 0 suddenly. This causes a change a momentum of bullet and impulse is applied. Technically the kinetic energy is converted to potential as a deformation occurs inside that object, transferring some of the kinetic energy into the object.
It causes the bullet to spin which makes it go straighter.
It can. The rifling in the barrel causes the bullet to spin. This usually keeps the bullet moving relatively straight (because of gyroscopic stabilisation). However, as the bullet slows down at longer ranges, the spinning can cause it to wobble and drift. This is called spin drift. Spin drift can be upwards, so yes, rifling can cause a bullet to go up, but only at extreme ranges.
Ok. So first there is the sound of the explosion in the bullet casing when the bullet goes off. Then when the bullet flies through the air and there is a slight sound. The sound is like when you whip something around so fast such a a rope. It goes so fast that it makes a wiffle sound like a wiffle ball. I hope this helped.
Gravity and air resistance will both play a part. Air resistance is likely to reduce speed and gravity will cause the bullet to be pulled towards the ground.
Rifling. The barrel is not smooth on the inside. There are small grooves spiraling down the barrel which makes the bullet spin. Nearly all shotguns do not have rifling in the barrel.
Projectile expansion or projectile tumbling.
An object in motion will stay in motion until acted on by another opposing force. So gravity causes a bullet to fall back to the ground, but wind and air resistance cause the bullet to not fall strait back from where it came, aka one barrel. ____________ The above is true, only if Newtons theories are correct. If Newtons Theories are incorrect, then the bullet performs in the manner The Creator of all things and happensings decreed that it will. [see discussion on this comment]
Rifling causes the bullet to spin through the barrel and downrange. This spin stabilizes the bullet, allowing it to maintain a straight course to the target. Without the spin, accuracy would be dismal.
Having a bullet-proof screen attached, and running it over with a truck usually does it for me.
Rifling a gun barrel causes the bullet to spin when it comes out. This makes the bullet fly more straight and greatly improves accuracy. Much like a spinning football spirals.
