Let’s look at a couple of examples for reference. Momentum is why even an old traditional bow shooting much slower than any modern compound bow can still manage to propel a heavy arrow completely through a big game animal.

The formula for momentum is p=mv very similar to kinetic energy, but in this case, mass and velocity are equally weighted in the equation. In other words, it is the ability of an object (an arrow in our case) to continue moving in a particular direction against resistance. In other words, we are more concerned with the penetration of the arrow than its “knockdown power,” and the best way to measure potential penetration is with momentum. What we as bowhunters want is for the the broadhead and arrow to pass completely through the animal, severing any arteries and cutting through any organs it contacts along the way. Ashby, an arrow will never produce the roughly 500 ft-lbs of kinetic energy needed to create hydrostatic shock (more on those figures later). With an arrow, though, we’re not concerned with how much “shock” or tissue damage outside the wound channel is created. Heavier arrows reduce stress on your bow and typically produce a quieter shot than a lighter arrow. In firearms lingo, it’s sometimes referred to as “knockdown power.” That works well for ballistics, because of the shockwave effect the bullet’s kinetic energy has on a game animal, damaging tissue well beyond the actual bullet hole.īut the benefits of a heavier arrow don’t just stop with better penetration. It is non-directional, so that when an object such as a bullet makes contact with its intended target, kinetic energy is released in all directions. Kinetic energy is actually a measurement of how much stored energy an object in motion has. The problem with using kinetic energy in choosing an arrow setup is that it’s not really applicable to how well an arrow will perform on a live animal.

In this formula, arrow speed is more influential than weight, because it gets squared. Kinetic energy is expressed in the formula K.E.=1/2mv 2, where m is the mass of the object (the arrow in this case) and v is the velocity (speed) of the arrow. Oftentimes proponents of lighter, faster arrows point to the arrow’s kinetic energy as support for their preferences.

With that in mind, let’s take a look at why heavier arrows can provide some valuable benefits over their lighter counterparts, and how to strike a balance between arrow weight and speed for the best of both worlds. Ashby has dedicated much of his life to studying arrow performance and broadhead lethality, and his research helped legalize bowhunting in South Africa and other sub-Saharan countries. Ed Ashby of the Ashby Bowhunting Foundation, whose mission is to “provide the bowhunter with the information to achieve highest possible success rate and reduce the wound/non-recovery rate of big game to the lowest level possible.” Dr. The information provided here was inspired by the research of guys much smarter than I am when it comes to physics, with a lot of information coming from Dr. Some of the science can be confusing and has been debated over the years. I’ve done a lot of reading on momentum, kinetic energy and their impact (pun intended) on arrow performance. What I failed to understand at the time, and for a long time after, was the importance of momentum and the role arrow weight plays in creating it.īefore I dive too deep into the topic, let me put a big asterisk on this article - a disclaimer of sorts - that I am not a physicist. I had no idea how fast my bow was shooting or why I needed it to be any faster, but I bought into the hype that faster was better, and it made sense to me that lighter arrows would shoot faster than heavy ones. While my meager bank account during my early bowhunting days kept me from getting too caught up in the speed craze, I do remember jumping on the bandwagon by putting an old overdraw setup on one of my first hunting bows so I could shave two or three inches off of my already heavy Easton XX75 aluminum arrows. The quest for speed not only led many hunters to buy the latest and greatest bow each season, but many of these same hunters also turned to their arrows and broadheads to squeak out every possible foot-per-second by going as short and light as possible. During that time, manufacturers often touted their bows’ IBO or ATA speeds above all other features, and hunters gladly handed over their hard-earned dollars for whichever models posted the highest numbers for that year. For decades now, bowhunters have seemingly been on a quest to own the fastest shooting bow possible.
