| abstract =  In this paper we present two methods, the nonholonomic method and the vakonomic&lt;br /&gt;
method, for deriving equations of motion for a mechanical system with constraints. The&lt;br /&gt;
resulting equations are compared. Results are also presented from an experiment for a&lt;br /&gt;
model system: a ball rolling without sliding on a rotating table. Both sets of equations&lt;br /&gt;
of motion for the model system are compared with the experimental results. The effects of&lt;br /&gt;
various forms of friction are considered in the nonholonomic equations. With appropriate&lt;br /&gt;
friction terms, the nonholonomic equations of motion for the model system give reasonable&lt;br /&gt;
agreement with the experimental observations. &lt;br /&gt;
