How legs become 150 km/h at the wrist.
Numbers: Front-foot contact returns 8–10× body weight, converted into ~200 J of rotational energy at the shoulder.
Technical Breakdown
19-section schemaDefinition
Bowling is a whip — passes leg → hip → trunk → shoulder → elbow → wrist, each segment amplifying speed.
Physics Involved
Each joint acts as a lever amplifying angular velocity. A 1% sequencing gain adds 2–3 km/h at release.
