What else can I help you with?
Will cannonball travel farther if shot from a longer cannon. why?
Yes, a cannonball will generally travel farther if shot from a longer cannon. A longer cannon gives the cannonball more time to accelerate and build momentum before exiting the barrel, resulting in a higher initial velocity and longer travel distance.
Which fires the farthest a long or short cannon?
A long cannon fires farther than a short cannon due to the longer barrel allowing for a longer distance through which the projectile can accelerate and gain velocity. This results in a higher muzzle velocity and longer range for the long cannon compared to a short one.
Why does a bullet have less momentum fired from a short barrel vs long barrel?
At the instant the gun fires, the bullet is at rest- speed zero. As the expanding gasses from the burning gunpowder reach the bullet, they begin pushing the bullet up the barrel. It's speed is increasing- and the longer the push, the higher the speed. There IS a point of diminishing returns- where a barrel LONGER than the perfect length begins to slow the bullet- you have used all the expanding gasses, and now friction is slowing the bullet. If you had a barrel 20 ft long, the bullet would not make it all the way up the barrel, it would stop.For barrels on any realistically-usable weapon, a longer barrel will provide more momentum to the bullet than a shorter one. In addition, longer rifled barrels will also impart more spin, which will increase accuracy.
An object is at rest. Once there is enough force to overcome the inertia of the object the longer the same force acts on the moving object the (lessergreater) its change in momentum.?
Greater. Since force is directly proportional to the change in momentum, the longer a force acts on an object, the greater the change in its momentum.
What the work energy theorem of a rifle with a longer barrel that fire bullets with a larger velocity than a rifle with a shorter barrel?
The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. In the case of rifles, the longer barrel allows for a longer acceleration distance for the bullet, resulting in a higher muzzle velocity. This means that the rifle with the longer barrel does more work on the bullet, giving it more kinetic energy and a higher velocity compared to the rifle with the shorter barrel.

Yes, a cannonball will generally travel farther if shot from a longer cannon. A longer cannon gives the cannonball more time to accelerate and build momentum before exiting the barrel, resulting in a higher initial velocity and longer travel distance.
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
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.
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.
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.
Why does a long-range cannon have a long barrel?
the longer the barrel the further it shoots and is more accrurate
Which fires the farthest a long or short cannon?

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.
Can you make a gun barrel longer?
You will have to replace the barrel
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.
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
