proper acceleration

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

(physics) The acceleration felt by an object, as opposed to the coordinate acceleration. For example the acceleration of an object at the surface of the Earth is 9.81 m/s² upwards, but has no coordinate acceleration. The proper acceleration of an object is Lorentz invariant.

日本語の意味

（物理学）物体が実際に経験する加速度。これは、座標加速度ではなく、物体自身が感じる加速度を指し、ローレンツ変換下でも変わらない不変の値となる。
