如何计算Angular Momentum
learn.whatIsHeading
Angular momentum measures rotational motion analogous to linear momentum. It's conserved in closed systems and calculated as the product of moment of inertia and angular velocity.
公式
L = I × ω where I is moment of inertia and ω is angular velocity
分步指南
- 1Enter moment of inertia I or calculate from mass/radius
- 2Enter angular velocity ω
- 3Multiply to get angular momentum
例题解析
输入
I = 5 kg·m², ω = 3 rad/s
结果
L = 15 kg·m²/s
