is constant
Precession may refer to:
Precession, one of the Euler rotations

Astronomy: precession of earth - Washington State University
The physical cause of the precession is a torque (twisting) of the earth, caused mostly by the sun's and the moon's gravity pulling on the equatorial bulges of the earth. If earth were NOT spinning, the sun and moon would pull the earth so that the bulges were flat in the sun-earth orbital plane. The planets have some gravitational influence ...

precession
precession/prɪˈseʃn; prɪ`sɛʃən/ n[U](also pre,cessionof the `equinoxes) gradual change in the angle at which the earth revolves daily, causing the equinoxes to occur slightly earlier in each successive year 岁差(地球自转角度的渐次变化, 使每年的春分点及秋分点比上年略为提前).

What causes precession and other orbital changes
Joakim Lodin. Yup, the strength of gravity changes from about 9.78 m/s^2 at the equator to about 9.83 m/s^2 at the poles, mostly because of the spin of the earth and the resulting centrifugal force. Gravity also changes depending on how high up you are: the further you get from the center of mass the lower the gravity.

Precession - Wikipedia
Precession. Nutation. in obliquity of a planet. 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. In other words, if the axis of rotation of a body is itself ...

How to fix precession in pedal axle? The axle on my bike that supports the pedals appears to have loosened, so that there is precession in it - I can slightly jiggle the pedals back and forth in a perpendicular direct...
You have a loose bottom bracket. It needs to be replaced. You need to buy a new bottom bracket, along with two special tools: A crank puller and a bottom-bracket tool. If your current bottom-bracket is cup-and-cone style (I'm betting it is), it can be removed with basic tools and elbow grease. If it...

How to normalize (dimensionless) the relativistic Binet's equation for mercury $$\frac{\delta^2 u}{\delta\theta^2}+u=\frac{\mu}{h^2}+3\mu u^2. $$ This is Binet's relativistic equation. I was trying to make perihelion...
Following the dimensionaly correct equation on wikipedia, you have $$\frac{d^2 u}{d\theta^2}+u=\frac{r_s c^2}{2h^2}+\frac{3r_s}2 u^2$$ with $$r_s=\frac{2G\mu}{c^2}$$ Now $u$ is inverse distance, so in order to make it dimensionless you need to multiply it with a constant with units of distance. The ...

Relativistic Precession
The special and general theories of relativity give three types of corrections to the Newtonian precession, of a gyroscope near a large mass such as the They are:

Larmor precession
In physics, Larmor precession (named after Joseph Larmor) is the precession of the magnetic moment of an object about an external magnetic field. This term describes Fermi–Walker transport and leads to Thomas precession. The second term is associated with Larmor precession.

Axial precession
Their combination was named general precession, instead of precession of the equinoxes. Lunisolar precession is about 500 times greater than planetary precession.
