When shooting, arrows actually bends as it moves forward!

When we describe the speed of something, we often say "flying straight like an arrow". In fact, this statement is incorrect. The arrow does not fly straight to the center of the target as we imagine, but twists and rotates forward. Why does the arrow that flies fast after leaving the string move forward in a curved manner? When the archer releases the bowstring in his hand, a great force will be generated on the tail of the arrow, and the bowstring will quickly return to its initial static position. At this time, the tail of the arrow will transmit kinetic energy to the arrow shaft.

Since the arrow cannot completely absorb the sudden kinetic energy, different parts obtain different speeds, causing the tail of the arrow to first obtain the energy generated by the string release, and it will move faster than the arrow head.

Arrows and tails with different forces About the curvature of recurve bows When an arrow leaves a recurve bow, the arrow will bend from left to right because the bowstring begins to return to its position after leaving the archer's fingers. The launch at this time adds the force of the horizontal element, which is why recurve bow archers need to use arrow side pads to make the arrow fly better when it leaves the bow.

Arrows that bend forward About the bending of compound bows When a compound bow shoots an arrow, there is no horizontal influence because the fingers do not directly touch the release of the bowstring (compound bows generally use a special release device to release arrows). The mechanical release eliminates the back-and-forth swing in the left and right directions, and the pressure applied by the bowstring is up and down. The arrow rest only touches the bottom of the arrow, so the arrow is launched in a state of shaking up and down.

Bending of compound bows and arrows Each arrow has two nodes when flying, one near the tail and one near the head. The node is the point where the arrow shaft can maintain the same position when other parts of the arrow body are bent. How about the two nodes of the arrow? Have you learned something new? Never say that the arrow flies straight in the future. Remember, the arrow is bent forward!
