A graph of average speeds versus time can give the acceleration due to gravity of the falling object.

平均速度——时间图表可以给出这个自由落体的重力加速度。

The direction of the acceleration due to gravity is straight down as shown in the diagram.

重力加速度的方向竖直向下。

If air resistance is neglected, and the speed of the object is measured over several short, consecutive intervals as it falls, the differences in the speed of the object can be used to determine the acceleration due to gravity.

如果忽略空气阻力，并在几个短暂、连续的时间间隔上测量物体的速度，就可以用物体速度的微分来计算重力加速度。

In the low-low satellite to satellite gravity mission, the intersatellite range and range-rate data are the observable values, while the intersatellite acceleration can be derived from the range-rate through digital differential. Using acceleration data, people can avoid solving the variation equations of the satellite motion and simplify the observation equations. But on the other side, the digital differential will amplify the observation noises and finally affect the solved geopotential accuracy.

低低卫星跟踪卫星的观测量是两低轨卫星的星间距离或星间速度，星间加速度由星间速度通过数值微分导出，用星间加速度作为观测量可以避免解算卫星运动的变分方程，简化观测方程的建立，但数值微分会使观测噪声放大，从而影响重力位的解算精度。
