It's very interesting because velocity seems to require two different times to define it -- the initial time and the final time.
这非常有趣,因为速度似乎需要两个时间才能算出来,初时刻和末时刻

This makes sense; the rate at which the cell population is growing, the derivative dX/dt, is proportional to the number of cells I have.
这个说的通,细胞数目的增长速度,就是导数dX/dt,和细胞数目呈比例关系
-
But de Broglie has told us that the wavelength is related to the instant velocity through this formula.
但德布罗意曾说过,波长是和瞬时速度相联系的,通过这个公式。
-
RAM You probably know your computer has something called RAM which is where documents and programs live just temporarily while you're running them 'cause RAM tends to be pretty fast and whereas your hard disk is where programs and files live permanently.
也许你知道电脑有一个,正在使用的程序和文件都暂时存放在那里,而且会加快电脑速度,而硬盘是程序和文件,永久存储的地方。
-
What de Broglie is saying we can know the wavelength of any matter at all, as long as we know its mass and it's velocity.
通过德布罗意所说的,只要我们知道了,它的质量和速度，我们可以知道,任何物质的波长。
-
That limit will be some arrow we can call the velocity at the time and it will always be tangent to the curve.
那个极限也就是一个矢量,我们称之为瞬时速度,并且它总是和轨迹相切的
-
So, if the speed was so and so now, then the time had to be this.
所以,如果速度在过去和现在都是这样,那时间就是这个
-
So the velocity at any part of the curve is tangent to the curve at that point.
曲线上任意一点的速度,都在该点和曲线相切
-
It says that, "If a body has an acceleration, then you need a force and the relation of the force to acceleration is this thing."
它是这么说的,"如果一个物体有加速度,那么你需要有一个力,力和加速度的关系是这样的"
-
Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.
好了，我们已经定义了，这些术语，我们知道了，频率和波长，现在可以来考虑,波的速度了，特别是光波的速度，速度等于它走过的距离,除以所用的时间，因为我们。
-
They tell you the initial location and initial velocity of the object.
它们表示的是物体的初始位移,和初始速度
-
The fact that you don't need a force for it to move forever at a given speed in a given direction, that's not obvious, because in daily life you don't see that.
对于物体不需要力的作用就能保持,确定的速度和方向持续运动这一事实,它并非显而易见,因为在日常生活中你看不到这种情况
-
For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
-
For example, if you're talking about the chalk--if I throw the chalk, you will have to know where it is and how fast it's moving.
比如说,这支粉笔,如果我扔出这支粉笔,你就像知道它的位置和速度
-
What is it you have to know about this object that was thrown, I claim, is the initial location of the object and the initial velocity.
关于这个物体,我们需要了解什么,我要强调的,就是这个物体的初位置和初速度
-
Now, a little later, and a little later later, because between the first and second, you get a velocity, the second and third you get another velocity.
现在,再晚一点,再再晚一点,因为第一个和第二个位置,你得到一个速度,第二个和第三个位置,你得到另一个速度
-
So，the point is,every object falling under gravity is given by the same formula, but there are many, many objects that can have many histories, all falling under gravity, and what's different from one object and the other object is, when was it dropped, from what height, and with what initial speed.
关键是,每一个受重力作用下落的物体,都有同样的表达式,但是各个受重力作用下落的物体,都有不同的初始条件,所以它们的区别在于,下落时刻,下落高度和初始速度
-
Second formula tries to relate the final velocity of some time, t, to the initial velocity and the distance traveled with no reference to time.
第二个式子能把某段时间t的末速度,和初速度,经过的路程联系在一起,并且不引入时间

-
If X is the number of cells, then the rate of change of X, dX/dt, the rate of change of the cell population, how fast division is taking is proportional to the number of cells I have.
如果X是细胞数目,那么X的改变率就是dX/dt,就是细胞数目的改变率,分裂的速度有多快,和细胞数量呈比例关系
-
So, the average is found by taking two instants in time, say t1 and later t2, and you find out where it was at t2 minus where it was at t1 and divide by the time.
平均速度就是取两个时刻,比如t1和之后的t2,用t2时刻的位移,减去t1时刻的位移,再除以这段时间
