Why is the speed of a cannonball greater when shot from a cannon with a longer barrel?

The energy needed to move a cannonball is created by burning fuel--usually gunpowder but nothing says they couldn't make a cannon that burned propane to fire projectiles. Anyway, if you're firing a round the speed of that cannonball is determined in part by how long the energy's being applied to it. The longer the barrel is, the longer the energy will be applied and the faster the cannonball will go.

A cannonball shot from a cannon with a long barrel will have a greater muzzle velocity because the cannonball receives a greater what?
Gunpowder burns, heat and pressure rise, ball accelerates Guns are designed so that the potential of the gunpowder is translated into momentum of the cannonball, if you hold the barrel diameter and cannonball size the same, the only way to increase the momentum (and velocity) is to apply the gunpowder force (pressure) for longer, this means: 1) A longer barrel 2) More gunpowder
Does a cannonball go faster if shot from a long cannon or a short one?
The long barreled cannon allows a longer time for the explosive charge to act upon the cannonball, which increases its velocity, making it go farther. You could also say the distance of the force of the long barreled cannon is greater, which increases its velocity, making it go farther.
Will cannonball travel farther if shot from a longer cannon. why?
Yes, because the longer cannon have more energy.
If a cannonball is shot from a longer barrel cannon rather than a shorter barrel cannon it willl have a?
Longer (effective) range. Longer barrels on a firearm allow for more complete burning of the propellant, which results in a higher muzzle velocity, which in turn results in a longer effective range, when compared to an identical weapon with a shorter barrel.
Why does a long-range cannon have a long barrel?
the longer the barrel the further it shoots and is more accrurate
What is the oldest long tom shot gun?
The term "Long Tom" was used to denote a muzzle loading cannon that had a barrel much longer than standard. While slower to load, it had greater range. Over the years it has been applied to guns with a longer than usual barrel, notably shotguns. It is a name used by several makers- the earliest that I have found is between the late 1890's and early 1900s, but they were made up into the 1920s."Long Tom" was an unofficial name for a muzzle loading cannon with a much longer than usual barrel- slower to load, greater range. The name was borrowed by shotgun makers around 1900 to denote a shotgun (usually a single shot) with a longer than usual barrel. Not a brand name, but a model name.
What is the advantage of a longer gun barrel?
Within limits, a longer barrel means a faster bullet. It is pushed by the expanding gasses from the fired cartridge for a longer time, and accelerates to a higher speed. A longer barrel will also mean a longer distance between the front and rear sight, permitting greater accuracy in aim.
Can you make a gun barrel longer?
You will have to replace the barrel
Does the length of a shotgun barrel affects the distance of the shot?
Yes, the longer the barrel the longer the shot.
How did the first explosive cannonball fuse work How did they prevent it from exploding while it was still in the barrel?
The fuse was shielded/wrapped with a non-flammable insulating cover for most of it's length. Longer fuse/more insulation: more distance before downrange ignition.
Does a longer airsoft barrel account to anything?
Longer barrels to increase accuracy and fps slightly, but getting tighter bore barrels has a much greater effect on both. Also, the effect of barrel length works in a way that the longer a barrel is, the less effect a barrel extension has. For example, replacing a pistol barrel with one that is 3 inches longer has a much larger effect on the pistols accuracy than adding 3 inches to a sniper rifle barrel has on the sniper's accuracy. Fps increases with increased barrel lengths are usually negligible, while tight bore barrels can increase fps by up to 15%. If you are going to change the barrel I would recommend a tight bore over a longer barrel (if you can do both then go right ahead). When buying a stock gun, barrel length is something to consider though, because the differences can be quite significant, especially between "normal" rifles and bullpups.
Why do mortars have short barrels?
a mortar has such a short barrel due to the fact that mortars are released from barrel at lower speed than cannon guns thus the need to rifle them and have long barrels is useless and so the tube does not need to be any longer than whats required to stabilize the flight and direction
