Over a period of nearly 26,000 years, the Earth's rotational axis moves in a circle with respect to the stars. This is known as precession. As a result, our current north star, Polaris, will appear to slowly drift and be replaced by a different north star. ... Make a new version of this Demonstration...

The version of the equation of time implemented here accounts for the variation of sidereal time with the precession of the equinoxes over a period of 26,000 years. The cylindrical plot of the equation of time shown here in 3D is implemented as a mechanical cam that ... Note: To run this Demonstration you need the free;

Precession refers to a change in the orientation of the rotation axis of a rotating body. It can be defined as a change in direction of the rotation axis in which the second Euler angle (nutation) is...

The precession of the equinoxes refers to the precession of Earth's axis of rotation with respect to inertial space. Hipparchus discovered that the positions of the equinoxes move westward along the ecliptic compared to the fixed stars on the celestial sphere.

Demonstration of gyroscopic precession ... Toy gyroscopes provide a good demonstration of precession. In this case it is not an applied weight which results in a couple but the fact that center of mass of the gyroscope is not above the point of contact and so the weight force and reaction force are offset.

Demonstration changes, new equipment and new demonstrations for Auburn Physics Department ... This can be used as a small scale demonstration of precession. Unlike the large bicycle demo of precession, the disk slowly falls over. It thus also demonstrates conversion of gravitational potential energy to rotational kinectic enegy.

[Archive] Help with precession experiment General Physics ... The best demonstration of precession would be: Spin the bicycle wheel, hang the bicycle wheel from a string attached to ONE side of the axis. Since the weight of the wheel causes a torque in a plane that is perpendicular to the angular momentum of the wheel;
