Research & Notes.
In-depth articles on the math and logic behind our tools — written for people who want to understand the calculations, not just run them.
The Physics of Kinetic Energy: Why Speed Matters More Than Mass in a Crash
Kinetic energy scales with the square of velocity, not mass. That single mathematical fact explains why a modest increase in driving speed disproportionately increases crash severity and stopping distance.
