What is Ballistics.run?
Ballistics.run is a simple demonstration site showcasing basic trajectory calculations. Think of it as a "toy" calculator - a quick, interactive way to see how different parameters affect projectile flight.
This is not a professional ballistics tool. It's a lightweight demo built to illustrate the core concepts of external ballistics in an accessible, browser-based format.
What It Does
The calculator performs simple point-mass trajectory calculations using basic physics:
- Drag force based on ballistic coefficient
- Simple wind drift approximations
- Drop and velocity calculations at range
- Energy retention estimates
What It Doesn't Do
This is an intentionally simplified tool. It does NOT include:
- Coriolis effect calculations
- Spin drift modeling
- Atmospheric density corrections
- Complex drag curves or multi-segment BC
- Aerodynamic jump or pitch damping
For Serious Work...
If you need production-grade ballistics calculations with full physics modeling, check out ballistics.rs - the complete simulator with advanced features, validated physics, and comprehensive environmental modeling.
Ballistics.run exists to demonstrate that you can do basic trajectory math in a browser. It's a proof-of-concept, not a substitute for professional tools.
Technology
Despite being a "toy," this site is built on the same open-source ballistics-engine Rust library used in production systems. We're just using a simplified subset of its capabilities.
Educational Use
This site is great for:
- Learning basic ballistics concepts
- Quick "back of the napkin" calculations
- Demonstrating trajectory physics to others
- Understanding how BC and velocity affect downrange performance
