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。
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?
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.

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
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。
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。
And I can therefore calculate S and what the velocity So what is the velocity in the x direction at point s?
然后我可以推测出,点在x轴方向的速度,what,the,velocity,在y轴方向的速度,那么在S点的x轴方向的速度,是多少呢?
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)。
Transform.postScale(float sx, float sy, float sz): Scales the 3D object in the x, y, and z direction.

Along the way I noticed another kind of critical junction and made another X and an arrow in the right direction.
路上又发现了一个关键的交叉点,于是又划了个“X”,并加上个右箭头。
The inertia terms and those relating to conduction in the X direction were also negligible.
惯性项和那些与X方向的导热有关的项也被略去。
The disturbances advances in the X-direction as a so-called surface or evanescent wave.
