Wisconsin statutes don't have a definition of the term "firearm", they do have a definition of "airgun" which would include a pellet gun. In the absence of a statutory definition, a term is construed by the dictionary definition "any weapon in which the projectile is propelled by the force of an explosion".
In addition, in the statute that prohibits weapons on school grounds, firearms are distinguished from airguns. This would be authority for the proposition that airguns are not firearms throughout Wisconsin laws.
You did not say the context of your question. It must be noted that Wisconsin has a broad definition of "dangerous weapon" which would include high powered pellet guns.
They propel their projectile by a different means than an actual firearm does. BB and pellet guns use air or spring propulsion, whereas a firearm's projectile is propelled by detonation.
No such thing. ANY firearm, including high powered pellet guns CAN produce a fatal injury.
A pellet Gun and a Air gun are the same thing. A pellet rifle and an air rifle are the same thing. You are most likely referring to a Pellet gun/rifle verses an Airsoft gun/rifle. Pellet guns fire a metal projectile up to 1.500 FPS (Feet per Second) and are used for target practice or hunting. Airsoft guns are capable of firing a 6mm plastic projectile up to 500 FPS and are designed to be used in Combat play where people shoot at each other. Much like Paintball only with less force. That's where the term "SOFT" come from. Unfortunately "AirSoft guns" are often mistakenly referred to as "air guns" when they should be referred to as 'AirSoft guns". Airsoft is considered more as a toy where "pellet air guns" are the next closest thing to a firearm with less power. Airsoft guns/rifles all have red tips to let everyone know that they can be shot at another person. Pellet air guns/rifles look similar to a firearm (NO RED TIP) and are never used in team play where people shoot at each other.
No... but the government does consider them to be very dangerous.
This will depend on the license laws in your jurisdiction- which you did give. MOST states in the US do not treat pellet guns as firearms. NJ treats all pellet guns as firearms. Great Britain and some members of the EU set limits on energy of the gun. Depends on where you are. In the case of a true firearm, speed does not matter- they are all firearms.
Montana has no law regulating non-powder (i.e., BB and air) guns.
Any of the PCP class of pellet guns or rifles. These are high pressure pellet guns that are capable of shooting a 50cal pellet.

Pellet guns and Pellet rifles.
Many modern 'BB' or Pellet guns will shoot a projectile at close to standard firearm speeds. You can buy a combo BB/pellet gun at big family stores for under fifty dollars that have a velocity of eight hundred feet per second. A lower velocity pistol is often only 60-100 feet per second faster. While the projectile in the BB/pellet guns is very small and light, it could easily pierce skin or eyes. So it can be very dangerous if mishandled. But so can many other things, so the importance of BB/pellet guns is to use them to teach safe handling of a firearm to prevent accidents.
No, that why they are named Air guns. Air is what drives the pellet or BB. <><><> Above is correct- however, if you mean a firearm, yes, they can work with no air. Gunpowder contains its own oxygen chemically combined.
Not all pellet guns use C02 some are designed to use a spring or pump. Pellet guns that use C02 are rapid fire guns and do not require re-cocking or pumping between each shot. BUT they usually have less power that spring or pump pellet guns.
