Because the centripetal force of Earth's rotation is stronger at the Equator.

因地球自转的向心力在赤道处更强。

Is this the centripetal force in action?

这运转时的向心力吗？

The other high tide you can think of is being caused by the Earth's centripetal force.

其它高潮你能够想象到由地球的向心力引起的。

Wow, centrifugal force. Actually, it's centripetal force, which is an inward force generated by the glass acting on the olive...

，离心力。实际上向心力。玻璃对橄榄作用产生的内向力。

But, as she's doing this swing, it's not just this centripetal force that's acting on her.

但，当她做这个摆动动作时，作用在她身上的不仅仅向心力。

And so what we have is called a centripetal acceleration to the inside.

所以我们称之向心加速度指向内部。

So there are centripetal motion. There is some net inward force going on here.

所以有向心运动。这里有一些净内向力。

But also, the force causing spinning balls to curve or hook is friction, not the centripetal force.

但，导致旋转的保龄球产生曲线或钩形轨迹的力量摩擦力，而不向心力。

I mean, why is there such a, what's the opposite of centrifugal, centripetal force in these medieval kingdoms?

我的意，什么这些中世纪王国里会有这种力量，正好和离心力相反，叫向心力？

The reason that people confuse the centripetal force with what feels like a centrifugal

人们混淆吸引力的原因 什么让你感觉像离心力？

With that much friction, micromice today can turn corners with a centripetal acceleration approaching 6 G's.

凭借如此大的摩擦力，今天的微鼠可以在转弯时达到接近6个G的向心加速度。

The inward component of the normal force alone is enough to provide the centripetal force required to stay on track.

仅靠法向力的向内分量就足以提供维持在轨道上所需的向心力。

Centripetal acceleration is equal to V squared over R. This V squared is for the center of mass of something moving around an axis.

向心加速度等于速度的平方除以半径。速度的平方指绕轴运动物体的质心。

When I'm going over a hill, there's a force, a centripetal force, it's like V squared over R, so you have 1g down normally, right?

当我越过一个山丘时，会有一个力，也就向心力， V 的平方除以 R，所以你通常会有 1 倍的向下力，对吗？

So, the acceleration that she experiences at the bottom of her swing is actually a total equals the centripetal acceleration plus acceleration due to gravity.

因此，她在挥杆到底部时体验到的加速度实际上等于向心加速度加上重力加速度的总和。

The steep angles help cars turn with less friction, because part of the normal force itself now points in to contribute to the centripetal force required.

陡峭的角度有助于汽车减少摩擦地转弯，因法向力的一部分现在指向内部， 有助于提供所需的向心力。

That means this car, this reference frame, has a  centripetal acceleration which is directed in towards the center of the circle which is  to your right.

这意味着这辆车， 这个参考系，有一个指向圆心（即你的右侧）的向心加速度。

Putting this back in our acceleration, or centripetal acceleration, V squared over r, plugging in numbers, we get 12.5 meters per second squared, which is roughly equivalent to 1.3 times gravitational acceleration.

把这个数据放回我们的加速度中，或向心加速度，即速度的平方除以半径，输入数字，我们得到的结果 12.5 米每二次方秒，这大致相当于重力加速度的 1.3 倍。

As the air that's routed above makes its way around the nose of the wing, it experiences centripetal acceleration, the force you also feel in a sharply turning car.

当从上方流出的空气绕过机翼前端时，它会产生向心加速度，您在急转弯的汽车中也会感受到这种力。

To do so, Chae studied the statistical relation between the observed  centripetal acceleration of particles in motion and the expected Newtonian acceleration from the  distribution of baryonic matter in the galaxies.

此，车研究了运动中粒子观测到的向心加速度与来自星系中重子物质分布预期的牛顿加速度之间的统计关系。
