  1. Why Doesn't a Spinning Wheel Drop Due to Its Own Weight?

    Apr 3, 2017 · In this perspective, τ points at the bottom of the page. I understand that that torque changes angular momentum of the wheel and the wheel starts precessing because of that …

  2. Understanding Precession in Special and General Relativity

    May 26, 2019 · The spin vector is such a quantity. The fact that evolves according to Fermi-Walker transport is the source of precession effects in both special and general relativity. …

  3. Minimal rotational kinetic energy for a gyroscope to precess

    Jan 17, 2024 · But as the spin rate drops, the precession rate increases (torque=), making the rotational energy about the diametral axis significant. Taking that energy into account, with a …

  4. Gyroscopic precession of a spin-stabilized bullet - Physics Forums

    Sep 4, 2023 · Hi! I am trying to understand the physics behind the gyroscopic phenomenon called spin drift. Spin drift occurs to bullets that are spin-stabilized over the course of their flight. Spin …

  5. What is the source of additional energy in a precessing gyroscope?

    Dec 28, 2014 · I'm trying to think about gyroscope precession in terms of energy, and I'm a little confused. If you hold the spinning gyroscope at some tilt so that it doesn't precess, it will have …

  6. Why do bullets precess in the opposite way from gyroscope …

    Dec 4, 2023 · 1) Bullet spin causes a bullet to become a gyroscope. Specifically, bullets have their center of pressure in front of their center of mass. Therefore, when pressed, gyroscopic forces …

  7. Why does Larmor precession appear to go against the right hand …

    Dec 23, 2013 · Why does Larmor precession appear to go against the right hand rule? kmm Dec 23, 2013 Direction Larmor precession Precession Click For Summary

  8. The precession of Mercury's orbit - Physics Forums

    Feb 13, 2020 · Hi, I was reading about the general relativity to get some basic understanding and it was said that the proper answer to problem of precession of Mercury was provided by the …

  9. Understanding Gyroscopic Precession • Physics Forums

    Apr 9, 2012 · The discussion revolves around understanding the behavior of gyroscopes and their precession compared to stationary rods. A key point is that a spinning gyroscope experiences …

  10. Can a gyroscope under no external force precess? - Physics Forums

    Dec 8, 2006 · A gyroscope can theoretically spin at intermediate precession angles, such as 45 degrees, due to the principles of angular momentum and precession. The discussion …
