Example data table
| Mass | Speed / Scenario | Stop distance | Energy (J) | Avg force (N) |
|---|---|---|---|---|
| 1.0 kg | 10.0 m/s | 0.05 m | 50 | 1,000 |
| 75 kg | 50 km/h | 0.50 m | 7,233.80 | 14,467.59 |
| 0.20 kg | 300 m/s | 0.02 m | 9,000 | 450,000 |
| 1000 kg | Drop 2 m | 0.10 m | 19,613.30 | 196,133.00 |
These samples use idealized averages for comparison.
Formula used
- Kinetic energy: KE = ½ · m · v²
- Drop height energy: KE ≈ m · g · h
- Momentum: p = m · v
- Average force from stopping distance: F̄ ≈ KE / s
- Average deceleration (distance): ā ≈ v² / (2 · s)
- Average force from stopping time: F̄ ≈ (m · v) / t
