The Earth causes the same gravitational acceleration of everything, even a doll and a flying Ping-Pong ball.

地球一视同仁地给予了万物同样的重力加速度，不论是小玩偶，还是飞行中的乒乓球。

We also talked about Kepler’s three laws, and calculated the gravitational acceleration on the surface of Mars.

我们还讲了开普勒三定律， 计算了火星表面的重力加速度。

So, you know how we've been describing the gravitational acceleration at Earth's surface as small g?

所以，你知道我们指的是重力加速度吗 在地球表面上用小写的g？

We also talked about Kepler's three laws, and calculated the gravitational acceleration on the surface of Mars.

当我们谈到开普勒三定律时， 我们计算了火星上的重力加速度。

So, you know how we’ve been describing the gravitational acceleration at Earth’s surface as small g? Well, small g is actually equal to big G, times Earth’s mass, divided by Earth’s radius, squared.

那么，您知道我们如何将地球表面的重力加速度描述为小 g 吗？好吧，小 g 实际上等于大 G 乘以地球质量，除以地球半径的平方。
