AI Thread Summary
The discussion centers on the angular velocity of a rod swinging from the ceiling, with a focus on its harmonic motion. The provided formula for angular velocity, ω = sqrt(g/l), is questioned in relation to the concepts of angular momentum and torque. It is clarified that the correct term to consider is angular frequency of oscillations, which differs from angular velocity. The distinction between these two concepts is emphasized, highlighting the need for accurate terminology in physics. Understanding this difference is crucial for solving problems related to physical pendulums.

Homework Statement


please check if my answer is ok.
There is a rod, with length L and maximum angle α swinging from the ceiling and making harmonical movement.
What is the angular velocity of the movement?

Homework Equations


ω = sqrt (g/l)

The Attempt at a Solution


that is the answer?
it's weird because we learn now angular momentum, torque and rigid body, and my answer has nothing to do with that.thank you.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
