First Integrals of the Equations of Motion, Kinetic Energy,ions are discussed that render a general theorem on work related to the increase of kinetic energy and possibly, for idealized systems, to the conservation of mechanical energy. Integration along a streamline is performed by keeping the time fixed, with the result known as the generalized . equation

Impact,ure, the loading in such a process acts with high intensity during this short period of time. As a result, the initial velocity distribution is rapidly changed (even pressure wave loadings, eg following an explosion, are events of that category). Such rapid loading in the contacting area is a source
