Best Answer

A bullet rotates in flight due to the rifling inside the barrel of a gun. The rifling creates grooves that grip the bullet and cause it to spin as it travels down the barrel. This spin stabilizes the bullet's trajectory and improves accuracy.

What causes a bullet to spin?

A bullet spins due to the rifling in the barrel of the gun. As the bullet is propelled through the barrel, the rifling causes it to rotate, promoting stability and accuracy in its flight. This spinning motion helps the bullet maintain a straight path towards its target.


How does a 22 caliber bullet act in the air?

A .22 caliber bullet typically travels at high speeds and maintains stability due to its small size and weight. It can be affected by factors like wind resistance, gravity, and air pressure, but it generally follows a straight path until it hits a target or loses momentum. The bullet can deviate slightly from its path due to external forces, but it is designed to be accurate over short to medium distances.


Does a bullet train travel faster than a bullet?

No, a bullet train does not travel faster than a bullet. A bullet can travel at speeds exceeding 1000 meters per second, while a bullet train typically travels at speeds ranging from 240-320 kilometers per hour.


Will a shot bullet land at the same time dropped bullet?

No, the shot bullet will land after the dropped bullet. This is because the shot bullet has an initial horizontal velocity in addition to the vertical acceleration due to gravity, while the dropped bullet only has the vertical acceleration due to gravity.


What is the difference between a 9mm bullet and a 45 cal bullet?

The main difference between a 9mm and a .45 caliber bullet is the diameter. A 9mm bullet has a diameter of 9 millimeters, while a .45 caliber bullet has a diameter of .45 inches. The .45 caliber bullet is larger and generally heavier than the 9mm bullet, resulting in differences in recoil, speed, and stopping power.

What causes a bullet to rotate on exit?

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.


What direction do you rotate the front sight of the M4 to move the strike of the bullet up?

To move the strike of the bullet up with an M4 front sight, you would need to rotate the sight post counterclockwise. This will raise the front sight, adjusting the point of impact higher.

Does the m-16 bullet tumble?

Technically, it doesn't. Bullets that are stable in air may "tumble" in tissue, or they may not; and "tumbling" itself is generally a mis-statement of what happens. Generally speaking, when a long spitzer bullet hits tissue (long relative to a pistol bullet or a round ball), the center of pressure of the bullet will radically shift forward, to approximately 30% of the length of the ogive behind the point of the bullet; which for most bullets will be very far in front of the center of gravity (and thus the majority of the mass). Because of this, the base of the bullet will tend to rotate around the center of pressure, past the nose once, or at most twice (due to inertia and the initial shock of the wound); and then the bullet will travel base forward (being led by it's mass) until it comes to rest, or exits the body (when it generally WILL completely destabilize and actually tumble). If the bullet travels far enough in tissue (somewhere between 14" and 20" depending on the exact bullet, and the density of the tissue), it will tend to rotate back to point forward, and then to base forward again. That's not exactly tumbling; and it's certainly not "cutting through flesh like a buzz saw", or anything like it. Source: http://anarchangel.blogspot.com/2007/02/terminal-tumbling.html

How does the spiral barrel on a gun work?

If you mean the spiral grooves inside of a rifle barrel- those are the lands (high spots) and grooves (low spots) that make up rifling. The bullet, being softer than the steel of the barrel, is pushed into the rifling when fired. The lands cut into the outer edge of the bullet, gripping it, and causes the bullet to rotate with the spiral. This rotation causes the bullet to travel in a straight line as it passes through the air- and is much more accurate than a smoothbore (no rifling) barrel. Ever notice how a football spins when a pass is thrown? Same thing.
