Question

Why does an arrow start to curve downwards soon after you shoot it?
Почему стрелка начинает загибаться вниз после того, как вы выстрелите в неё?

Answer 1

The arrow can't react to all this energy instantaneously, and different parts gain momentum at different speeds. ... In an arrow shot from a recurve bow, the bend is to the left and right because the string has to get around the archer's fingers on its way back to its resting position.
