RE: To heck with KE formulas and theories

True. But what I was trying to get at is that you could weigh down arrows with super heavy broadheads, melted-in weights, added weight tubes, etc... (going for more and more mass for max momentum)...

RE: To heck with KE formulas and theories

Arthur I can't wait to see you flinging some walled brass tubing as arrow shafts that weigh about 3lbs an arrow! Momentum right?

I think you'll even admit that there's a happy medium, even for...

RE: To heck with KE formulas and theories

You mean to say you directed its KE to go in a specific direction, which gives the momentum. You don't "direct" momentum. You use energy to impart a direction to mass.

You said "momentum is...
