Discussion Overview

The discussion revolves around the angle formed between the direction of impact and the length of an arrow as it leaves a bow. Participants explore whether this angle exists, its implications, and potential methods to reduce it, touching on aspects of archery and arrow dynamics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the angle between the direction of impact and the length of the arrow, questioning if it can be reduced.
  • Another participant suggests that the direction of impact and the direction of arrow motion typically coincide, indicating a possible misunderstanding of the initial question.
  • A later reply reiterates the inquiry about the angle and proposes that the arrow usually leaves the bow at a slightly upward angle while impacting the target at a slightly downward angle, attributing this to the nature of archery.
  • Suggestions are made for reducing the angle discrepancy, including using a stronger bow, lighter arrows, or employing mechanisms like cams for increased thrust. Creative solutions such as active guidance or shooting in specific conditions (e.g., on the vomit comet) are also mentioned.

Areas of Agreement / Disagreement

Participants express differing views on the existence and nature of the angle between the direction of impact and the arrow's length, with no consensus reached on the specifics or the best methods to address the angle.

Contextual Notes

There are assumptions regarding the definitions of the angles discussed, and the effectiveness of proposed solutions remains unresolved. The discussion does not clarify the conditions under which the angle may vary.

TL;DR
what can the angle between the direction of force of impact and the length of the arrow be?
sir,
I would like to know what the angle formed between the direction of impact and the length of arrow that leaves a bow? If it exists can it be reduced?
thank you

Usually direction of impact and direction of arrow motion coincide. Maybe I am not catching you.

Are you referring to the tension in the string of the bow?

The direction of the arrow as it leaves the bow will usually be slightly upward. The direction of the arrow as it impacts the target will usually be slightly downward. That is why they call it archery.

If you want to reduce the discrepancy between the two angles, you want a faster arrow. Stronger bow, lighter arrow, shortened range, maybe cams to apply more thrust through the release, maybe a crossbow.

Or maybe get really creative with active guidance.

Or do your shooting on the vomit comet.
