Precessional or processional physics
WebRobert E. Terry received the B.S. degree in physics from the Massachusetts Institute of Technology, Cambridge, MA, followed by the M.A. and Ph.D. degrees from Johns ... Web3) Static gravitational and magnetic fields create a torque or "twisting force" acting perpendicular to both the field and the direction of the angular momentum. The gyroscope or nucleus does not "tip over" but is instead deflected into a circular path perpendicular to the field. 4) The resultant circular motion is called precession.

WebMagnetic Torque Equals Gravitational Torque. This is a statics experiment. A gravitational torque is applied to the ball by a weight on an aluminum arm inserted in the ball's handle. When the magnetic torque is adjusted to equal the gravitational torque: µ × B = r × mg. Here, r is the radial distance of "m" from the center of the ball. http://hyperphysics.phy-astr.gsu.edu/hbase/top.html
Webthe surface of a cone. Give it a nudge, however, and the axis will start gyrating wildly around the vertical, its motion tracing a cone ( drawing ). The spinning Earth moves like that, too, though the time scale is much slower--each spin lasts one day, but each gyration around the cone takes 26 000 years. The axis of the cone is perpendicular ... WebApr 13, 2004 · good day to you, good sir or madam! i am in a bit of a predicament with a physics assessment of mine; i need to know the mathematical relationships between the precessional frequency, the couple (or torque, as i have read it called) and the angular momentum of a gyroscope, and (here comes the tricky bit) i would like to understand it...
WebThus, the value of the spin vector precessional frequency, ωS, is given by Eq. 14b. ωS = [MSgµHz]/\ (14b) From Eq. 14b, the values of ω are directly related to the same factors as the magnetic energy associated with coupling to the field. For two states with the same absolute value of MS, but different signs of MS, the precessional rates are WebAmerican Institute of Physics. 1 Physics Ellipse College Park, MD 20740 +1 301.209.3100.

In astronomy, precession refers to any of several gravity-induced, slow and continuous changes in an astronomical body's rotational axis or orbital path. Precession of the equinoxes, perihelion precession, changes in the tilt of Earth's axis to its orbit, and the eccentricity of its orbit over tens of thousands … See more Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. … See more • Larmor precession • Nutation • Polar motion • Precession (mechanical) See more • Media related to Precession at Wikimedia Commons • Explanation and derivation of formula for precession of a top See more Torque-free precession implies that no external moment (torque) is applied to the body. In torque-free precession, the angular momentum is … See more Torque-induced precession (gyroscopic precession) is the phenomenon in which the axis of a spinning object (e.g., a gyroscope) describes a cone in space when an external torque is applied to it. The phenomenon is commonly seen in a spinning toy top, … See more

When a torque is exerted perpendicular to the angular momentum L, it produces a change in angular momentum ΔL which is perpendicular to L, causing it to precess about the z axis.
