Angular momentum- rotating rod - Physics Forums
Feb 15, 2025 · The angular momentum of the assembly about its center is not the difference of the contributions from the two masses. It is the sum. If you want to perform a proper parallel axis computation to shift the reference axis, you could start with the angular momentum about the one axis: The sum of the angular momenta of the two masses about the fixed ...
What is the angular momentum of a spinning solid sphere
Dec 27, 2003 · What is the angular momentum of a spinning solid sphere of mass 'm', equitorial velocity 'v', and radius 'r'? (The mass of the sphere being uniformly distributed and the spin being along a single axis only) I can't figure this out because the …
Difference between "Spin" and "Angular Momentum"? - Physics …
Jun 29, 2015 · Orbital angular momentum is a kinetical quantity of a moving body, it can always be related to the change of spatial degree of freedom. EDIT: I didn't pay a close attention to your question, I thought you wrote orbital angular momentum. So, spin is an angular momentum, just orbital angular momentum is.
Is the Angular Momentum of a Pendulum Conserved? - Physics …
Jan 30, 2019 · No, the angular momentum ##L = mvl##, where m is the mass of the ball and v is its speed at an instant. Note, this is an example of (non-uniform) circular motion whereby vector v ##\perp## radius vector r at all instants.

Direction of Torque and Angular Momentum - Physics Forums
Jul 15, 2011 · Then, when all the angular momentum is lost in the ball, the ball will stop, then start to drop while starting to move faster and faster around its vertical axis. The speed at which it drops (which can be pictured as the magnitude of the angular momentum vector) determines how fast it will be spinning.
Angular momentum and centripetal force - Physics Forums
Sep 19, 2016 · Suppose you have a ball on a string, and you make the ball to move around in a circle. The force on the ball is caused by the tension of the string, and is called the centripetal force F = mv^2/r. If you were to let go at any moment, the ball would stop rotating and move with linear velocity...
Is angular momentum always conserved? - Physics Forums
Jan 15, 2015 · You have not shown how the velocities and rotation rates resulting from the collision were derived. With three conserved quantities (linear momentum, angular momentum and energy) you should be able to solve for three results (ball velocity, rod velocity and rod rotation) in such a way as to conserve all three.
Angular Momentum of Mass: Understanding the Equations and …
Jul 4, 2015 · I was objecting to using L = mvr to determine the angular momentum of the body when it is rotating about any axis, such as the axis through the centre of the rod. I merely said that "The equation L=mvr (for a rigid body rotating about an axis such this 50 g mass rotating about an axis through the centre of the rod) ... is true only for point ...
