Angular Momentum کا حساب کیسے لگائیں
Angular Momentum کیا ہے؟
Angular momentum describes the rotational motion of objects, analogous to linear momentum. It's crucial for understanding spinning objects, orbits, and rotational dynamics.
فارمولا
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
مرحلہ وار گائیڈ
- 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
حل شدہ مثالیں
ان پٹ
m = 1 kg, v = 10 m/s, r = 0.5 m
نتیجہ
L = 5 kg·m²/s
Perpendicular distance crucial
عام غلطیاں جن سے بچنا ہے
- ✕Using linear momentum formulas instead of angular versions
- ✕Forgetting that distance r must be perpendicular to velocity
اکثر پوچھے جانے والے سوالات
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.
