Kinetic energy is the energy something has because it is moving — a rolling ball, a running person, a flying plane. A still object may have other energy stored in it (often called potential energy), but it has no kinetic energy until it moves.

Kinetic energy動能 is the energy something has because it is moving是某樣東西因為在移動而擁有的能量 a rolling ball, a running person, a flying plane像滾動的球、奔跑的人、飛行中的飛機 A still object靜止的物體 may have other energy stored in it可能儲存著別種能量 (often called potential energy)（通常叫做位能） but it has no kinetic energy until it moves但在它動起來之前，沒有動能

Artists also talk about kinetic art: sculptures that actually move, with motors, magnets, or wind.

Artists also talk about kinetic art藝術家也會談到kinetic art（動態藝術） sculptures that actually move真的會動的雕塑 with motors, magnets, or wind靠馬達、磁鐵，或風來運作

The word sounds technical. In ordinary chat people just say moving or about motion. Scientists and designers use kinetic when they want the precise label.

The word sounds technical這個字聽起來很專業 In ordinary chat平常聊天時 people just say moving or about motion大家就只會說moving或about motion Scientists and designers科學家和設計師 use kinetic會用kinetic when they want the precise label當他們想要用精確的說法時

It is an adjective, so it needs a noun: kinetic energy, kinetic sculpture, kinetic theory.

It is an adjective它是形容詞 so it needs a noun所以後面需要接名詞 kinetic energy, kinetic sculpture, kinetic theory像kinetic energy、kinetic sculpture、kinetic theory
