- Why Doesnt a Spinning Wheel Drop Due to Its Own Weight?
This is the experiment I am a bit confused about this part: There is a torque on the wheel from its own weight That's the τ on the picture 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
- Gyroscopic precession of a spin-stabilized bullet - Physics Forums
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 drift starts with an induced rotation in a spin stabilized bullet As a bullet flies through the air
- The precession of Mercurys orbit - Physics Forums
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 general relativity Then, I started reading about the precession of Mercury orbit "Mercury deviates from the precession

Undergrad How to quantify gyroscopic precession torque? rcgldr Jun 4, 2024 Precession Torque Click For Summary
- What Are the Units for Precession Rate (Ω)? • Physics Forums
The precession rate is given as ##Ω = \frac {Mgr} {Iω}## What are the units here?: I'm calculating it as ##\frac {1} {rad s}## Am I supposed to interpret
- Direct vs. Retrograde Precession - Physics Forums
(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 precession: direct or retrograde If the body is flat, the precession is retrograde: the spin and precession rates have
- Understanding Precession in Special and General Relativity
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 Precession in Flat Spacetime Consider a particle moving in a circular orbit of radius in the equatorial plane in flat spacetime Define a comoving orthonormal basis of 4-vectors:
- Why do bullets precess in the opposite way from gyroscope diagrams?
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 cause a bullet to spin 90 degrees instead of tumble See this diagram: 2)The precession does not cause the
