Abstract


Here we show how to separate into variables the scalar kinematic equation $V^{2}=V_{0}^{2}+2\vec{a}\cdot\Delta\vec{r}$ in Cartesian coordinates, a procedure that is little considered in the school texts on general physics, and also the connection between the kinematic expression and the theorem on work and kinetic energy. We also show a generalization of this same kinematic equation.
