  1. Direct vs. Retrograde Precession - Physics Forums

    Oct 16, 2017 · (This is not about the motion of the planets.) If one takes a body in space (not outer space, necessarily) with only central forces, it may exhibit one of two types of …

  2. Gyroscope precession - WHY? (What's the cause?) - Physics Forums

    Feb 25, 2006 · This piece of information clears my doubts and explains why the gyroscope makes de precession motion. But why does the body tend to rotate around a line which is a principal …

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

    Sep 4, 2023 · Gyroscopic precession occurs when the bullet translates this forward rotation 90 degrees due to gyroscopic precession. Thereby, the bullet translates some of the downward …

  4. Orbital Precession Calculation: Unit Explained - Physics Forums

    Jan 26, 2023 · Hi, I've just calculated the orbital precession for the earth using the sigma formula of general relativity. What is the unit of the result? Degrees per century or arcsec?

  5. Precession: Explaining the Linear Motion of a Spinning Wheel

    Oct 2, 2009 · So, I understand the idea of precession on a gyroscope: we've got the angular velocity vector, the angular momentum vector (same direction but times the inertia tensor), …

  6. Intuitive understanding of Thomas precession - Physics Forums

    Jan 24, 2014 · The Thomas precession is a purely kinematic effect resulting from the non-commutativity of Lorentz boosts. In Galilean relativity the generators of boosts all commute …

  7. Understanding Gyroscopic Precession - Physics Forums

    Apr 9, 2012 · If the precession angular speed Ω is defined to be the rate of change in the angle about the pivot with respect to time, this gives Ω = τ/L End. I have made vectors bold and also …

  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 the Relativity-Induced Precession of Mercury's Orbit

    Mar 20, 2011 · Can someone explain the cause of the Precession of Mercury’s Orbit in a "language" so simple that my grandmother can understand it? I mean only the part (43 arc …

  10. Torque-Free Precession of Spinning Plates - Physics Forums

    Apr 17, 2005 · To have a precession you need to have an external torque. If torque is zero, no precession occur- the angular momentum must be conserved. The visible "precession" could …
