Abstract  The form invariance of Appell equations of holonomic mechanical systems under the infinitesimal transformations of groups is studied. The definition and the criterion of the form invariance of Appell equations are given. This form invariance can lead to a conserved quantity under certain conditions.
Keywords:  form invariance      Noether symmetry      Appell equations      conserved quantity
