Formula and methodology
Formula: Average stopping force = ½m(v in m/s)² / stopping distance.
The model converts initial kinetic energy into work over the entered stopping distance to produce an average force magnitude.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Vehicle mass — kg; minimum 1.0E-6; maximum 1000000
- Initial speed — km/h; minimum 0; maximum 10000
- Stopping distance — m; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Vehicle mass | 1500 |
| Initial speed | 50 |
| Stopping distance | 0.8 |
Average force ≈ 180,845 N.
Assumptions and limits
- Speed is converted from kilometres per hour to metres per second.
- All initial kinetic energy is represented by work over one stopping distance.
- This is not a crash-safety, injury, vehicle-damage, or legal reconstruction tool; peak force and restraint behavior are not modeled.
