PNL Testers

NEWTONIAN PHYSICS — APPLIED TO ARCHERY

PNL Testers is beginning a new video series exploring the physics behind the shot.

From the moment the arrow begins to accelerate until it reaches and penetrates the target, its behavior is governed by physics.

We'll follow the arrow through acceleration, flight, impact, and pe*******on, applying:

• Newton's Three Laws of Motion
• Work-Energy Theorem
• Impulse-Momentum Theorem

This won't be just equations.

Real bows. Real arrows. Real measurements. Real testing.

Watch the official series trailer below.

Coming Soon — Newtonian Physics Applied to Archery

PNL Testers — Physics Never Lies

Newtonian Physics / PNL SHORTS | PNL Testers This series applies Newtonian mechanics to real-world archery using real bows, real arrows, real measurements, and real testing.

The Understanding Mass Series is Complete!

If you've ever wondered why arrow mass matters, this series is for you.

Over six short videos, we cover:

✔️ The difference between mass and weight
✔️ Why arrows are measured in grains
✔️ How to calculate kinetic energy
✔️ How to calculate momentum
✔️ How these concepts work together

These concepts provide the foundation for understanding arrow flight and pe*******on.

The next series, Newtonian Physics, will build on this foundation and explain how Newton's Laws govern what happens from the moment the string is released until the arrow reaches the target.

Physics Never Lies.

Understanding Arrow Mass / PNL SHORTS | PNL Testers Learn the difference between arrow mass and weight, how mass affects velocity, and how mass and velocity are used to calculate kinetic energy and momentum.

Understanding Arrow Mass — Parts 1 through 5 are now available.

This series starts with the basics of mass and weight, then works step by step through measuring arrow mass, kinetic energy, and now momentum—all using the same physics that applies to an arrow in flight.

There is one more part left to complete the Understanding Arrow Mass series. Part 6 will bring everything together in a final recap.

All five current parts can be watched in order at the link below.

Part 4 is now added to Understanding Arrow Mass

I’ve already shared Parts 1 and 2 of my Mass Fundamentals series here on Facebook, and Part 3 is now finished.

Instead of continuing to post each one separately, I’m sharing the link to the Mass Fundamentals page on the PNL Testers website. This keeps the series together and makes it easy to start with Part 1 and watch them in order.

I’ll continue adding Parts 4, 5, and 6 to the same page as they’re released.

The goal of this series is to build the physics one piece at a time—starting with what mass actually is, then working toward how we use it in arrow physics.

New Research Papers Added

Two papers have been added to the PNL Research Library that examine arrow pe*******on from a Newtonian mechanics perspective.

• Understanding Pe*******on: A Newtonian Perspective
Introduces the fundamental physics governing arrow pe*******on.

• Pe*******on Mechanics: A Force-Based Perspective
Builds upon those concepts by examining force, work, and resistance during pe*******on.

These papers are intended to provide a physics-based foundation for future PNL laboratory test methods and standards.

As always, constructive comments and technical discussion are welcome.

Lethality - The Lethality section explores the scientific principles that influence terminal performance in archery. Topics include pe*******on physics, broadhead design, wound […]

I'm excited to announce the release of PNL-TS-002 Rev. 1.0 – Standard for Measuring Archery Projectile Pe*******on Performance.

This document establishes a standardized framework for documenting archery pe*******on testing, including projectile specifications, launch and impact conditions, environmental data, calculations, measurement requirements, and reporting. The goal is to improve repeatability, transparency, and meaningful comparison between tests.

PNL-TS-002 is the foundation for future PNL Test Methods that will provide detailed procedures for specific pe*******on tests.

I welcome constructive feedback as the PNL Standards continue to evolve.
