Hello I am new here an the only thing I know about physics is how to spell it. So if you folks would be so kind I have a question. It is about archery and arrows. Years ago when bows were slower you could shoot about any arrow with little difficulty. Today as bows are becoming much more efficient there is a need to build better and better arrows. In doing so it appears there is a need to understand some of the physics behind the way an arrow reacts when shot from a bow. I have done some research and found that the anatomy of an arrow has three specific points along the length of the arrow. 1 is the FOC balance point. This point is determined by taking a finished arrows adding a point on the end and balancing it to find its FOC or Front Of Center point 2 is the front Node also known as the centre of mass, this point lies somewhere between the FOC balance point and the front tip of the arrow 3 is the back Node of the centre of drag, this point lies somewhere between the FOC balance point and the rear tip of the arrow. There are those in archery who feel you can go through a series of steps to bounce the arrow off the corner of a table to identify the front Node. Their thought is you can place the arrow on the edge of the counter or table and lay the back of the arrow in your hand or on another table and pull down on the arrow and let it go to watch the bounce. Then move the arrow forward of that point and back from that point and repeat until you find a dead spot. They believe this is the node! My question is this, if they are correct in finding the front node in this way would the node be in the same place when the arrow is shot from a bow. You have an arrow that you are bouncing by hand sideways and the only energy placed on the arrow if from the process of pulling the arrow down and letting it go to make it bounce. compared to an arrow that is being launched in a horizontal plane after the energy of the bow is placed on it. Thanks in advance.
