| 摘 要： | 直接求解史瓦西时空中自由粒子的测地线方程,得出粒子运动方程的一般常见形式.此方法与一般教材中根据史瓦西度规的静态球对称性以及四速归一条件得出的运动方程完全相同.此方法物理意义更清晰、明确,同时对理解弯曲时空中的测地线方程具有重要意义.

| Abstract: | The usual form kinematics equations of a free particle are obtained via directly solving the geodesics equations in the Schwarzschild space time.Comparing with the method in some text books,where the kinematics equations are given by the spherical symmetry of space-time and normalized four-velocity,the results are completely same.However,the geodesics method is more physical,and it is useful and meaningful to understand geodesics equations in a curved space-time. |
