Does a bullet shot from a gun undergo any acceleration after it leaves the barrel?
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
When a rifle is fired horizontally the bullet leaves the barrel and doesnt drop at all for the first 35 meters of flight Is this true?
No, this statement is not true. When a rifle is fired horizontally, the bullet immediately begins to drop due to gravity as soon as it leaves the barrel. The rate of drop will depend on the muzzle velocity of the bullet and the distance it has traveled.
Define trAjectory of the bullet velocity of the bullet velocity?
Bullet trajectory is the path the bullet travels once it leaves the barrel. Bullets travel on a long arch and cross the line of sight twice. Once shortly after leaving the barrel and once again on target assuming the sights are properly zeroed. This is the trajectory of the bullet. Bullet velocity is the speed at which the bullet is traveling along it's trajectory.
What makes a bullet spin?
The barrel of the gun has lands and grooves (grooves and ridges) cut in a spiral. The bullet molds to these and starts to spin as it moves down the barrel. The bullet just continues to spin after it leaves the barrel.Correct. The ridges are known as 'lands'. It is possible to calculate how fast a bullet will spin if you know the twist rate of the barrel and the velocity of the bullet. My AR15 has a twist rate of 1-in-8 ie for every eight inches the bullet travels down the barrel, the bullet is rotated once. It fires a .223 round at approx 2,800 feet per second so... The formula is (bullet velocity x 720)/twist rate so... (2,800x720)/8 is an incredible 252,000RPM!
Is a bullet leaving a muzzle at it's full speed?
No, a bullet does not reach its full speed immediately upon leaving the muzzle. It needs time to accelerate due to the forces acting on it like wind resistance and gravity. The bullet will gradually reach its maximum velocity as it travels through the air.
What is the formula for muzzle velocity?
No specific formula. MV is the speed that a bullet is moving when it leaves the muzzle of a firearm. It is measured. Variables that affect it include bullet weight, size, powder charge, composition of the bullet, and length of barrel.
How does a bullet leave a gun?
A bullet leaves a gun barrel because it is forced out by the pressure of burning gasses.
What is a muzzle for a gun?
It is the opening at the front of the gun where the bullet leaves the barrel.
What is a muzzle in a gun?
It is the hole at the front end of the barrel where the bullet leaves the gun.
What would cause a bullet to explode after it leaves a rifle barrel?
how fast it is going
Does a shotgun sabot slug rise after it leaves the barrel of the gun?
No, a sabot slug does not rise after it leaves the barrel of a gun. No bullet rises after it leaves the barrel of a gun. It always falls from the line of sight of thebarrel. All firearms have to be "sighted in" a bit high to hit a target downrange. At close range, there is little time for a bullet to drop and hit "low" on the target. Down range, however, the drop is more significant. The more time a bullet is in flight, the more it drops below the line of sight of the barrel. But a bullet always begins to drop below the line of sight of the barrel after it leaves the muzzle. Always.
Does a bullet shot from a gun undergo any acceleration after it leaves the barrel?
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
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 causes a bullet to spin when fired?
Rifling in the barrel is actually grooves cut into the barrel by the manufacturer to cause the bullet to spin as it leaves the barrel. Before rifling the bullets would tend to tumble when they left the barrel causing them to have shorter range and be less accurate.
When a rifle is fired horizontally the bullet leaves the barrel and doesnt drop at all for the first 35 meters of flight Is this true?
No, this statement is not true. When a rifle is fired horizontally, the bullet immediately begins to drop due to gravity as soon as it leaves the barrel. The rate of drop will depend on the muzzle velocity of the bullet and the distance it has traveled.
What factor affects a firearm's maximum projectile range?
The weight and shape of the bullet, the speed at which the bullet leaves the gun, and the degree of tilt of the barrel above the horizontal.
Does a bullets trajectory rise before it drops?
The line of sight of the bore of the firearm is tilted up. When the bullet leaves the barrel, it is traveling up, and will fall back through the line of sight.
