Vaidya’s spacetime is the simplest non-static generalization of Schwarzschild’s solution to Einstein’s field equation. Vaidya metric represents radiating universe.With the aid of differential forms, various geometrical quantities related to Vaidya metric are obtained. We obtained the electrical parts of the Weyl tensor, it is found that they are related to the radial vector. We explored kinematic parameters in the terms of Ricci rotation coefficients. Also, we investigate behavior of general observer quantities at naked singularity r = 0.
