向心加速度

在此注意，向心加速度与r是成正比的。

Notice that the acceleration , the centripetal acceleration is linear in r.

本文利用精密离心机转速与其向心加速度之间的对应关系对SAW加速度计的测量数据进行了计量标定。

The SAW accelerometer was calibrated using the relationship between the rotating speed of the centrifugal machine and its centripetal acceleration .

所以你需要，This，v，equals，omega，rv=ω，向心加速度，依然毫无商量余地。

R and therefore , you require centripetal acceleration towards the center & that is non-negotiable .

如果此时，我想让你转得更快，即v更大，那么向心加速度也会随之增大。

Now I 'm going to swing you faster , so the v will go up and so the centripetal acceleration will go up .

运动中不因r变化的是ω，故以此公式为准，向心加速度，与r成正比。

Since omega is the same for the entire motion you really have to look at this equation and you see that the centripetal acceleration is proportional with r.

这样我们，就能求出向心加速度。

And we can calculate now what the centripetal acceleration is .

但这里却没有力，能提供向心加速度。

But there is nothing to provide that centripetal acceleration .

因而需要一定的向心加速度，才能绕着圆周旋转。

And so you need a certain centripetal acceleration to go around in that curve .

给出了向心加速度的精确表达式及在加速度计坐标系的分量，同时也给出了重力加速度在加速度计坐标系下的分量。

The component of centripetal acceleration and gravity is also given under the accelerometer coordinate .

这叫做向心加速度。

It is called the centripetal acceleration .

这个向心加速度，对这个物体达到点，来说是必须的。

And that centripetal acceleration D is a must for this object to reach that point D.

小球受到绳子的拉力，这就是向心加速度的来源。

This ball is feeling a pull from the string and that provides it with the centripetal acceleration .

试管的内壁和液体正朝这个方向，推动微粒，并提供向心加速度。

The side of the glass and the liquid is pushing in this direction to provide this centripetal acceleration .

但是别把这个切向加速度，它是沿着圆周的，和向心加速度混淆。

Do not confuse ever the tangential acceleration , which is along the circumference , with a centripetal acceleration .

现在我要把向心加速度，和能被感知到的重力联系起来，来看看我们是如何感知重力的。

I 'm going to make a connection between centripetal acceleration and perceived gravity The way that you perceive gravity .

则现在，必然等于m乘以向心加速度，嘿，看起来太眼熟了。

So what I get now is must be m times the centripetal acceleration Hey ! That looks very familiar .

前提要求就是，具有向心加速度，朝这个方向，向心力的作用。

There is a requirement that there is a centripetal acceleration , which is in this direction , a centripetal .

再用ω2乘以行星，与太阳的平均距离，就能得到向心加速度。

And then I take omega squared times the mean distance to the sun and this is , of course , the centripetal acceleration .

绳子连接着，转盘与小球，因此，其拉力产生，向心加速度。

The string forms the connection between the rotating disc and the ball and therefore , the pull is responsible for the centripetal acceleration .

通过建立五个坐标系，计算各坐标系间的姿态矩阵关系，得到向心加速度和重力加速度在加速度计各轴上的分配。

Here establish five coordinate systems to calculate the relationship between attitude matrix , get the centripetal acceleration and gravity acceleration on the three axes .

因此得出无懈可击的结论，这向心加速度，是由引力引起，并呈1/r2递减。

Therefore , you cannot escape the conclusion that the centripetal acceleration which is the result of gravity , falls off as one over R squared .

先前在讲行星时，我们讨论过这个，我们讨论的是，匀速圆周运动，而且我们评估了，向心加速度。

We have discussed that earlier when we dealt with the planets , and we dealt with uniform circular motions , and we evaluated the centripetal acceleration .

于是我用对数坐标，作了张图，列出了向心加速度，与平均距离的关系。

So what I did was I plotted this data , the centripetal acceleration versus the mean distance to the sun and I did that on log paper .

另外，结合回归分析法，发现通风器内腔和通风管段的分离效率与向心加速度和湍流强度呈现一定的线性关系。

In addition , it is found that the separation of inner Cavity and ventilating pipe is linearly related to the centripetal acceleration and turbulence intensity using Regression Analysis .

这个向心加速度，就像我们记得的，甩一桶水的时候，等于。

And that centripetal acceleration , as we remember from when we played with the bucket of water , v ^ 2 / r that is v squared divided by R.
