Why do dropped phones land screen-down?
Show answer & explanation
Answer: Phone rotates during fall
Phone rotates during fall ✓ — Correct! Physics, not bad luck! Phone typically held with screen facing up, slight tilt when dropped. Phone begins rotating as it falls (angular momentum from initial tilt/slip). Typical drop height (~1-1.5m) gives phone time for ~180° rotation—lands screen-down. Center of mass + initial conditions determine rotation. Higher drops = more rotation (might complete 360°, landing screen-up). Shorter drops = incomplete rotation, lands screen-up/edge. Butter-side-down toast = similar physics!
Murphy's Law applies — Wrong. Feels like Murphy's Law, but actual physics: initial tilt + rotation during fall + typical drop height = screen-down landing more probable.
Air resistance flips it over — Wrong. Air resistance affects fall, but rotation comes from initial angular momentum when phone slips from hand at angle.
