Temperature is a measure of those atoms' kinetic energy.

温度是那些原子动能的量度。

Faster motion increases the kinetic energy of the molecules and atoms.

更快的运动速度导致了粒子的动能增大。

Wind turbines convert the kinetic energy of the wind into mechanical power.

风力涡轮机将风能转化为机械能。

1 Joules, or half the kinetic energy of the cheddar.

1 焦耳，或切达干酪动能的一半。

And calculating the kinetic energy of rotational motion is pretty easy.

寻找运动中的动能 旋转很容易。因为首先，惯性矩。

The MSKT distributes the kinetic energy by crushing the rail while shooting it to the side.

MSKT 通过压碎铁轨同时将其发射到侧面来分配动能。

At those two turning points, the ball won’t have any kinetic energy, since it isn't moving.

在这两个转折点， 球不会有任何动能， 因为它没有移动。

When the box was resting on the ground, we'd say that it had no kinetic energy.

当盒子还在地上时， 我们说他没有动能。

So the total momentum stays the same, but you lose some kinetic energy because there’s less speed involved.

所以总动量保持不变， 但是你失去了一些动能， 因为涉及的速度变慢了。

So now, the kinetic energy of the Swiss is twice the kinetic energy of the cheddar.

所以现在，瑞士人的动能是切达干酪动能的两倍。

As the car slows, the electric motor operates in reverse, capturing the vehicle's kinetic energy to recharge the battery.

当汽车减速时， 电动机反向运转，捕获车辆的动能为电池充电。

So the total momentum stays the same, but you lose some kinetic energy because there's less speed involved.

所以整体势头将保持不变，但我们输了 由于速度降低而产生的一些动能。

At those two turning points, the ball won't have any kinetic energy, since it isn't moving.

在这两个转折点上，不 球具有动能，因为它没有移动。

It has more kinetic energy, because its atoms and molecules are moving around more.

而且它有更多的动能，因为 它的原子和分子运动得更多。

In thermodynamics, there are a few different ways to describe the kinetic energy of a system.

在热力学中，有许多不同的方法 描述系统的热能。

Maybe not an ideal situation for commercial navigation through the river but a perfect scenario to capture the water's kinetic energy to spin a turbine to generate electricity.

对于商业航运来说，这种情况也许并不理想，但对于利用水的动能来旋转涡轮机发电来说，却是再好不过了。

And you don't lose much energy when jumping, so if you could store the kinetic energy back in the spring on landing, the efficiency could be near perfect.

而且跳跃时你不会损失太多能量，所以如果你能在着陆时将动能储存回弹簧中，效率可能接近完美。

So you eject more electrons, and these electrons have a higher speed, and achieve a higher maximum kinetic energy, which is the kinetic energy of the fastest-moving electrons leaving the plate.

所以你射出更多的电子， 这些电子的速度就更高， 达到更高的最大动能，也就是运动最快的电子离开极板的动能。

If you listened carefully, you learned the difference between the net velocity of a gas and the average velocity of its particles, and that both things have a lot to do with the mass and kinetic energy of the particles.

如果你仔细听，你就会了解到气体的净速度与其粒子的平均速度之间的差异， 并且这两者都与粒子的质量和动能有很大关系。
