The spin is forced on to the bullet or shell by grooves in the gun barrel, this is to take advantage of the fact that the axis of a rotating object will tend to remain parallel, this , in effect keeps the shell or bullet in a good aerodynamic profile, without tumbling (which absorbs energy). These grooves are known as rifling and so any weapon which has those grooves in the barrel is said to be rifled.

What quantities remain constant in projectile motion?
All that I can think of are: 1.) Gravity 2.) Wind 2.A) wind speed 2.B) direction of wind 3.) Angle of trajectory 4.) Initial speed of projectile 5.) Material through which projectile travels (as in density) 6.) Mass of projectile 7.) Spin 7.A) speed of spin 7.B) axis/axes spining occurs on 8.) Shape of projectile 9.) Temperature of medium projectile is in 10.) Size of projectile (as in height, width, and depth) 11.) Weighting of projectile 12.) Obsturctions to projectile's path In a vaccuum, though, these are the variables: 1.) Speed of object 2.) Obstructions in path 3.) Gravity
Why spin motion is important for satellite?
Spin motion establishes a direction for the satellite to point to and stabilizes the satellite.
What two factors determine a projectile's range?
The two main factors that affect the range of a simple projectile are the angle and speed of the launch. Both of these can be included in the launch velocity, which is a vector that is usually split up into vertical and horizontal components for processing.There are other factors, like wind resistance (including spin/swing) and changes in gravity, but these are fairly insignificant unless you need high precision or are dealing with projectile motion on a large scale or with objects that aren't dense.
Does adding spin to an object to an object increase accuracy?
it increases the stability of the projectile. so yes it would help create consistency and accuracy.
What causes turbines to spin in hydroelectric power?
Heat
What is the function of rifling?
To impart a longitudinal spin to a projectile which gives gyroscopic stability to the projectile which greatly increases its accuracy.
What is the purpose of the gun barrel?
The purpose of the barrel is to direct the projectile and to contain gases pushing the projectile. Barrels are also commonly used to mount sights.

What is a gun barrel?
That portion of the firearm through which the projectile is propelled by the burning of the powder charge. Unless a smoothbore, it also imparts spin on the projectile to stabilize it.
What causes a tennis ball or a coin to spin?
When the ball hits the tennis racket, topspin (preffered stroke of tennis) makes the ball spin. The upward motion of the racket hitting the tennis ball.
Spin causes electrons to?
Spin causes electrons to exhibit magnetism.
What is the motion of the spin of the earth?
Rotation
How does a moons motion compare to a planets motion?
They both spin on an axis.
How does a moon's motion compare to a planet's motion?
They both spin on an axis.
What is rifling of the firearm?
The lands and grooves in the barrel that impart spin to the projectile
Inside the barrel increased range and accuracy?
Rifling refers to helix-shaped pattern of grooves and bands that have been formed into the inside of the barrel of a firearm to impart a spin to a projectile around its long axis. This spin gyroscopically stabilizes the projectile and improves its accuracy and stability.
