重力加速度 Gravitational acceleration
（重定向自Acceleration of free fall）
重力加速度（Gravitational acceleration）是一个物体受重力作用的情况下所具有的加速度。重力加速度会随高度增加而下降。
假设一个质量为m的质点与一质量为M的均匀球体的距离为r时，质量所受的重力大小为：
其中G为重力常数。 根据牛顿第二定律
可得重力加速度为
Acceleration of free fall

Gravitational acceleration 重力加速度
（重定向自Acceleration of free fall）
In physics, gravitational acceleration is the acceleration on an object caused by force of gravitation. Neglecting friction such as air resistance, all small bodies accelerate in a gravitational field at the same rate relative to the center of mass. This equality is true regardless of the masses or compositions of the bodies.
