The force, as this weight drops is constant, mgh and so the work is just going to be m g h, h where this is h.

当重物掉落时候的力是恒定的，因此做功就是，这段长度是。

Otherwise, I'm going to get a new guess by taking g, x over g, adding them, 2 and dividing by two.

或者呢，我会有一个关于g的新猜想,就是X大于g，将二者相加，然后除以。

So, we know in this example the initial height should be 15 meters and the initial velocity should be 10, and for acceleration, I'm going to use -g and to keep life simple, I'm going to call it -10.

我们知道在这个例子中,初始高度为15米,初始速度为10,然后是加速度,我们用"-g"表示重力加速度,为了计算方便,加速度的值取为-10

I'm going to start with a guess, I'm going to call it g. And then I'm going to say, if g squared is close to x, stop.

我会从一个猜想开始，把它叫做g，然后我会说，如果g的平方接近于X，打住。

Let me show you one more class, though about-- sorry, let me show you two more classes of algorithms. Let's look at the next one g- and there's a bug in your handout, it should be g of n and m, I apologize for that, I changed it partway through and didn't catch it.

请大家看，额,在你们的课堂材料中有个错误,应该是g，很抱歉-,我改了一部分这个错误但是没看到这里的，好，这儿的增长率，有人想猜猜么？

I know this is the right answer, because if I now find the acceleration, I find it's mg divided by m and I get -g as the answer for all bodies.

我知道这个等式是正确的,因为现在如果我要求物体的加速度,用 mg 除以 m,我就得到 -g,这个结果对所有物体都成立

For example, we know that if a body is near the surface of the Earth, the force of gravity of that object seems to be m times g, where g is 9.8.

例如,我们知道,如果在地球表面有一个物体,该物体受到的重力大小为 m 与 g 的乘积,g 等于 9.8

Right. The most famous example is that when things fall near the surface of the Earth, they all have the same acceleration, and the acceleration that's common is called g, and that's 9.8 m/s^.

最有名的例子就是,当物体地球表面附近下落时,它们都拥有相同的加速度,这个普遍的加速度叫做g,大小为9.8m/s^
