It is the same as angular velocity. If the angular velocity in rotational motion is ω, the period is T, and the frequency is ν, then the relationship is ω=2π/T=2πν, and so it is called angular frequency. It is 2π times the usual frequency ν. [Mitsuo Muraoka] [Reference] |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
角速度と同じ。回転運動における角速度をω、周期をT、その振動数をνとするとω=2π/T=2πνの関係があるところから角振動数という。通常の意味での振動数νの2π倍である。 [村岡光男] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
