Cara Menghitung Angular Momentum
learn.whatIsHeading
Angular momentum describes the rotational motion of objects, analogous to linear momentum. It's crucial for understanding spinning objects, orbits, and rotational dynamics.
Rumus
The calculator applies L = m × v × r or L = I × ω
- L
- m × v × r or L = I × ω — m × v × r or L = I × ω
- I
- I value — Variable used in the calculation
Panduan Langkah demi Langkah
- 1Input mass, velocity, and perpendicular distance from rotation axis (r)
- 2The calculator applies L = m × v × r or L = I × ω
- 3Results show angular momentum magnitude and direction
Contoh Terpecahkan
Masukan
m = 1 kg, v = 10 m/s, r = 0.5 m
Hasil
L = 5 kg·m²/s
Perpendicular distance crucial
Kesalahan Umum yang Harus Dihindari
- ✕Using linear momentum formulas instead of angular versions
- ✕Forgetting that distance r must be perpendicular to velocity
Pertanyaan yang sering diajukan
Why do ice skaters spin faster when they pull their arms in?
Angular momentum is conserved; decreasing moment of inertia (I) causes angular velocity (ω) to increase.
Is angular momentum conserved?
Yes, in systems with no external torque. This is why planetary orbits remain stable.
