Abstract

The precession movement contains surprising and attractive details that although they cannot be examined in depth at the medium level, they can be presented and displayed with elements as simple as a spinning top or a bicycle wheel, using appropriate rudimentary approaches, basically consisting of reason about the effect of the angular impulse applied on the system by the moment of the acting force. These pages show how it is possible to gradually go deeper into the application of the angular impulse law, maintaining the reasoning of physical sense to transcend the rudimentary approaches, without entering the usual mathematical treatments.
Finally, it shows how to incorporate ideas into a simple calculation program that solves all situations, and allows them to be explored through the manipulation of initial values.
