Neurons propagate slowly in axons, 100 meters per second, tops.

神经元在轴突中传输的速度较慢， 最多 100 米每秒。

Which is 343 meters per second.

也就是 343 米每秒。

We went from 5 meters per second squared to 10 meters per second squared.

从5m/(s^2) 变为 10m/(s^2)。由此我们可以得出 力与加速度为正比例关系。

InSight is now traveling at a velocity of 2,000 meters per second.

“洞察”号火星探测器正在以每秒2000米的速度飞行。

So 9.8 meters per second times the mass.

所以9.8m/s乘以质量。

Intercept velocity will be 11 meters per second.

对接速度是每秒 11 米。

InSight is now traveling at 1,000 meters per second.

“‘洞察’号火星探测器目前正以每秒1000米的速度飞行。

What's the relative velocity? - 12 meters per second.

相对速度是多少？- 每秒 12 米。

And it can travel up to six meters per second.

它可以每秒飞行6公尺。

Your acceleration is going to be 4.9 meters per second squared.

这个力，也就是平行於斜面的这个地心引力的分力。

I can grab the MAV at 5 meters per second.

我能抓住速度为 5 米每秒的飞行器。

Earth's equator is spinning around at hundreds of meters per second.

赤道以每秒460公尺的速率转动。

Just then the Gulf Stream's speed was 2.25 meters per second.

这时，海湾暖流的速度是每秒2.25米。

And gravity accelerates something at 9.8 seconds-- 9.8 meters per second squared.

重力加速度是9.8所以我要用12 我要推。

As that happened the velocity of the water 2,000 cubic meters per second was released.

当这种情况发生时，每秒2000立方米的水流速度被释放出来。

The booster's speed was slowed to about 10 meters per second by a parachute.

助推器的速度受降落伞影响减慢到大约10米/秒。

今年到目前为止，伊泰普大坝的平均流量为每秒6800立方米。

The current prototype works at wind speeds ranging from 1.5 to 7 meters per second.

目前原型机运转所需风速在每秒1.5到7米之间。

Workers at Itaipu say the dam normally averages an inflow of about 11,000 cubic meters per second.

伊泰普大坝的工作人员说，通常情况下，大坝的平均流量大约为每秒1。1万立方米。

The engineers who built the robot said it can walk at a speed of 2.1 meters per second.

制造该机器人的工程师说，它可以以每秒2.1米的速度行走。
