This study reported a computational error and its resolution calculation of a differential equation related to the relativistic motion of objects with variation gravitational acceleration and friction using the hep of a computer algebra system Reduce or programming language with Taylor series Numerical method. This study has successfully performed two computational conditions between non relativistic falling motion of a body with the relativistic motion of objects corrected by variation of the acceleration of gravity and friction. Taking the truncation error in computation into insideration, we obtained the result z = 1.0999 ± 0.001 unit of length. The difference between the value of non-relativistic motion of falling objects with corrected relativistic motion of objects with variation of gravitational acceleration and friction is 0.005 unit of length.
