Archery ballistics

How long or thick or heavy should an arrow be? Why are quarrels and bolts short, and is this good? Longbows and crossbows.

I spent a few hours trying to find all the great and clear pictures I had of barrelled arrows, in vain - sorry about that. Several people in the comments have said that I am using the terms 'inertia' and 'momentum' in a confusing manner. People are generally familiar with the fact hat heavy things do not want to go anywhere, and that when they are moving they are difficult to stop, and I used the terms to describe these two things. Both inertia and momentum vary with mass, so what I said was not wrong, but it is also true that some physicists will use the term 'inertia' also to describe the reluctance of a moving body to being slowed down. I apologise to any physics teachers out there who want to get the complete definition of 'inertia' into the heads of their pupils.
