Earth's axial precession, a slow wobble of its rotational axis, is analogous to the gyroscopic motion of a spinning top. The primary cause of Earth's precession is the gravitational influence of the ...

The Earth’s axis of rotation is shifting due to climate change and movements in the Earth’s interior. The corresponding polar motion is triggered by shifts in mass such as the melting of polar ice ...

If you’ve ever played with tops, you know that some spin easily while others wobble. Ever wonder why? The answer has to do with rotational inertia, a property shared by all rotating systems. Sometimes ...
