The point-mass equation of motion is usually given in the form of an explicit expression for the acceleration U.dot (vector). The modified point-mass equation is obtained by adding yaw-of-repose terms to the right-hand side. These new terms are functions of U.dot (vector) so that U.dot (vector) now occurs on both sides of the equation. In this report, the modified point-mass equation is rewritten in the form of an explicit expression for the acceleration.
