Understanding Arrow Mass

A step-by-step look at arrow mass, grains, velocity, kinetic energy, and momentum and how these measurements are used in archery physics.

Part 1 — Mass vs. Weight

Part 2 — Why Do We Use Grains?

Part 3 — What Does Your Arrow’s Grain Number Tell You?

Part 4 — Calculating Kinetic Energy

Part 5 – Calculating Momentum

Part 6 – Mass, Weight, Kinetic Energy & Momentum Recap

Understanding Mass Series Complete

Congratulations! You've completed the Understanding Mass series.

You now understand:

  • The difference between mass and weight
  • Why arrows are measured in grains
  • How to calculate kinetic energy
  • How to calculate momentum
  • Why these measurements matter in archery

These concepts provide the foundation for understanding arrow flight and penetration.

 

Coming Next: Newtonian Physics

In the next series, we'll use Newton's Three Laws of Motion to explain how forces control arrow flight and penetration.

From the moment the string is released until the arrow reaches the target, Newton's Laws explain every stage of arrow flight.

Physics Never Lies.
