Tips

usage
Two registers: in physics class it's strict 'kinetic energy'; in economic news it's a stock metaphor — 动能 'new growth drivers', 释放动能 'release impetus', 转换动能 'shift the engine of growth'.
memory
'movement' + 'energy' → energy of movement. Mirrors the English 'kinetic' (Greek kinētikos = moving).
