Abstract

An exactly harmonic potential seldom occurs in nature; a small anharmonicity is almost always present. In analytic calculations such perturbation terms present considerable difficulties. In numerical calculations on the computer, on the other hand, it makes scarcely any difference whether the potential is harmonic or anharmonic. In what follows we shall again consider the one-dimensional motion of a point mass with mass M = 1kg. Friction will be ignored. The potential of the restoring force has the form
$$V(x)\, = \,A\frac{{|x{|^{B + 1}}}}{{(B + 1)}}.$$
