Second... Newton's Second Law: ma this is the only force in the x direction.
根据牛顿第二定理：,等于。，ma，equals。。。,这是x方向的,唯一一个力。
So, the direction of the force is going to be that of x, y, z.
所以方向是。
There is no acceleration in the y direction, only in x direction when it starts moving, and that's why we split it.
在y方向上没有加速度，只有在x方向上移动时才有，这就是分解它的原因。
When it is at a random position x, there is a force on it and the force is always in the direction opposing the increasing potential energy so the force is clearly in this direction.
当它在随机位置x处，存在一个作用力，这个力一直在，势能增加的，反方向，所以这个力很明显，在这个方向。
Now what I want to find,actually, V is what are these two vectors, let's call them U and V, that correspond to moving a bit in the x direction or in the y direction?
现在我实际上想知道的是，这两个向量是什么，我们称它们为，U和，两者对应的是x方向和y方向一点位移？
OK, so, if I have a point, at any point, I can slice the graph of my function by two planes, one that's going along the x, one along the y direction.
如果我有一个点，任意一点，我可以用2个平面把函数图像切开，一个是沿x方向，一个沿y方向。
For velocity in the x, y, or z direction.

And the frictional force, in this case will adjust itself just the right way so that Newton's Second Law in the x direction will give you, for the force, a zero.
其它情况下，摩擦力会根据情况调节自身,此时在x方向上使用第二定律,合力为0就是结果。
Unit vectors are always pointing in the direction of the positive axis x in the x direction is this one.
单位矢量,始终指向,轴的正方向,轴方向的单位矢量，and，the，unit，vector,是这个。
x Well, we know how to compute partial w over partial x y or partial w over partial y, which measure how w changes if I move in the direction of the x axis or in the direction of the y axis.
我们知道如何计算∂w/∂,或者∂w/∂,这衡量了我在x轴,或者y轴方向上移动时，w的变化。
Therefore the acceleration since I call - that the "plus x direction"-- that was my plus sign-- must come out plus.
因此加速度必然,是在x正方向-,这里是正好，必然如此。
x Xo must be x zero-- - which I conveniently choose zero-- plus 133 meters per second, which is the velocity in the x direction, which never changes.
回到这个点的时候，x，then，when，it，is，back，at，this，point，肯定是-,为了方便我用0表示-,加上133米每秒，这是X方向的速度，它没有变过。
So this one equals m1 g cosine alpha - and this one, the x component-- which is in the minus x direction now-- equals m1 g sine alpha.
得到m1gcosα,而x方向上-,这里是x负方向-,大小是m1gsinα
Because once you move in the direction to Freedom from X, you start to put yourself in opposition to X.
因为一旦你从x走向自由，你开始把自己放在了X的对立面。
Transform.postScale(float sx, float sy, float sz): Scales the 3D object in the x, y, and z direction.
postScale(floatsx, floatsy, floatsz)：在x、y、z方向伸缩3D对象。
of the force in the x direction.
若只在y方向移动。
The x axis is positive in the right direction, while the y axis is positive in the downward direction (again, this is in contrast to its traditional upward direction).
x轴在右边为正值，但是y 轴在下方为正值（这与传统的上方为正值相反）。
The motion is only in the x-axis, along the x direction.
只在x轴，沿着x轴的方向进行移动。
Let this be the direction of increasing x, and so before the collision I have a certain amount of momentum.
方向为x正轴方向，在碰撞前，它有一定动量。
x but you better believe that there is one y So only when we deal with the y equations - does this acceleration come in-- not at all when we deal with the x direction.
方向上如果没有加速度，There，is，no，acceleration，in，the，x，direction,但是你最好相信,方向是有加速度的。，in，the，y，direction。,所以当我们处理y的方程时,需要考虑到加速度-,与处理x方向完全不同。
And with the same cross section, compress strengths in X direction of specimens with different height were almost the same.
横截面积相同，高度不同的压缩试件在X方向的压缩强度相差不大。
The inertia terms and those relating to conduction in the X direction were also negligible.
