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.

Even in twelve minutes, I only touch on this, and as you'll see from the awkwardness of the edit, I forget to say near the start that I was talking mainly about flight arrows - those designed for great range. 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.
