We discuss the wobbling motion in a lens-shaped body rotation, focusing on the frequencies and the
amplitude of nutation by filming the rotational motion and wobbling of the body. The friction
coefficient of the surface is altered to examine its influence for two lenses with
different curvature radii. MATLAB programs are developed to retrieve the Euler angles, which are
graphed according to time. It is shown that the lens with a smaller curvature radius exhibits the
wobbling effect in all cases, whereas the lens with a larger curvature radius shows such behaviour
in limited circumstances. The study confirms that the friction coefficient has a negative linear
correlation with the vertical axis declination amplitude with the R -squared value 0.878, showing
that friction gives damping and causes smaller axis declination amplitudes. Negative linear
correlation also exists with relation to the number of wobbles before the motion stops, where the R
-squared value is 0.938,…
