Abstract:

In this paper,the basic equations of motion of coins under different

conditions are derived. The problem of the coin's motion around a circle is analyzed,and two

special modes of motion are discussed using the results,which are finally verified via

experiments and numerical simulations.

Key words: coin, disk, rotation mode, nutation, stability
