Can a Cherry Dropped from 10,000 Feet Crack a Human Skull? Physics Analysis

No. A cherry (~1–2 g, ~1.5–2 cm diameter) reaches terminal velocity quickly due to low mass and high drag.

Physics Estimate

• Terminal velocity (vₜ) ≈ √(2mg / ρAC_d) ≈ 10–15 m/s (22–33 mph).
• Kinetic energy at impact: KE = ½mv² ≈ 0.5 × 0.0015 kg × (12 m/s)² ≈ 0.11 J.

Skull Fracture Threshold

Human skull fracture requires ~60–100 J (depending on site, angle, bone density). A cherry delivers <0.2 J — three orders of magnitude too low.

For comparison: A 150 g baseball at 40 m/s (90 mph) ≈ 120 J — can fracture skull. A cherry is harmless.

Myth likely confuses mass/velocity scaling. Air resistance dominates for small, light objects.
