So here comes the work that Walter Lewin has to do when we go from infinity to that point, which is capital R, radius, from this object.
所以,这就是,我要做的功,从无穷远处移到这点,也就是距离这个物体,距离为R处。
The formal definition is that the gravitational potential energy at a point P is the work that I, Walter Lewin, have to do to bring that mass from infinity to that point P.
形式定义就是,它在点P的重力势能,等于我,将物体从无穷远处,移动至点P所做的功。
Because of the special behavior of infinity, NaN, and 0, certain transformations and optimizations that may appear harmless are actually incorrect when applied to floating point Numbers.
由于无穷大、NaN和0的特殊行为,当应用浮点数时,可能看似无害的转换和优化实际上是不正确的。
