And we write, often for that gravitational acceleration, the letter " g ". 我们通常,用字母g表示,重力加速度。
Since all objects in this lecture hall and the earth fall with the constant acceleration, which is g we can write down that the gravitational force m would be m times this acceleration, g. 由于地球上的所有物体,都受向下的恒定加速度g影响,因此我们可以把重力写作,此加速度g乘以。
I now would like to write down, in most general form the equation for the position and the velocity as a function of time for a one-dimensional motion whereby the acceleration is constant. 我来把更一般的形式,写出来吧,在一维空间中,位置和速度,作为时间函数的,一般形式,这里的加速度是一个常数。
