I am a bit confused about this. I was purchasing some Arrows for my bow recently and wanted some light weight arrows for a flatter trajectory. I was looking at some really lightweight carbon arrows and The man at the bowyers shop it wasn't ncessessary. I asked him why and he told me that the draw on my bow would reach the upper bounds of the arrows capability way too soon and the remaining energy would be directed back into the bow. Excess energy being directed into the back of the bow is common knowledge, thats why you don't dryfire bows.
Now I was under the impression that an object had no upper bounds of kintic energy. I got home and looked it up on Wikipedia and found this definition:
So that got me thinking, If it's related to the amount of work needed to put the arrow into motion, then 1) why is Excess energy directed back into the bow, and 2) As long as an arrow will retain its integrity, the amount of force behind the arrow would only increase it's Kinetic Energy.Kinetic energy (also called vis viva, or living force) is energy possessed by a body by virtue of its motion. The kinetic energy of a body is equal to the amount of work needed to establish its velocity and rotation, starting from rest.
Now I realize some arrows are rated for certain draw weights or they will come apart if shot from a fast bow. Thats not what I am referring to, the Carbon Arrows I was looking at were WELL within the specs for my bow.
So my question is this. Does an object have an upper bound for Kinetic energy or does the kinetic energy increase limitlessly based on the force putting it in motion? Is it based on Mass of the Object or is it based on the Work needed to put the object in motion?
