Galileo measured the acceleration of gravity through experiments.

伽利略通过实验测量了重力加速度。

The acceleration of gravity is the acceleration of an object in free fall.

重力加速度是物体自由下落时的加速度。

In physics class, we learned about the concept of acceleration of gravity.

物理课上，我们学习了重力加速度的概念。

The acceleration of gravity on the Moon is only one-sixth of that on Earth.

月球上的重力加速度只有地球的六分之一。

On the Earth's surface, the acceleration of gravity is approximately 9.8 meters per second squared.

在地球表面，重力加速度大约是9.8米每秒平方。

The force of gravity is such that it produces an acceleration of about 32 feet per second for every second that an object falls.

重力使物体每降落一秒钟产生大约每秒32英尺的加速度。
