Is Angular Momentum Conserved About Point O?

Click For Summary
SUMMARY

Angular momentum is conserved about point O due to the absence of external torques acting on the system. The discussion references the equation M(P) = d/dt (h(P)) + v(P) x mv(G), which illustrates the relationship between angular momentum and linear momentum. The conservation principle is affirmed as a fundamental law of physics, indicating that in a closed system, the total angular momentum remains constant. This principle is crucial for understanding rotational dynamics in physics.

... without looking: because that's the Law.

What makes you think it might not be?
