The energy to be dissipated (proportional to the square of the combined speed of bird and plane) would be more like half a ton being dropped ten feet.

被消耗的能量(与鸟和飞机的速度相加的平方成正比)将大约是半吨的重物落下十英尺。

Without proof-- - you will see this if you ever take 803-- I will tell you that the speed of sound is the square root of Young's modulus divided by the density of the material.

现在不证明-,你们将在803章学到-,我告诉你们声速,是杨氏模量的平方根,除以介质的密度。

By the laws of physics, the increase in drag equals the square of the increase in speed, so even a slightly faster flight requires a lot more fuel.

根据物理定律，阻力的增加相当于平方的速度增加。

Sometimes they give you the speed in miles per hour, kilometers per year, pounds per square foot.

有时候速度的单位是英里/小时,千米/年,英磅/平方米

Whenever you see a particle moving in a circle, even if it's at a constant speed, it has an acceleration, v square over r directed towards the center.

只要看到质点做圆周运动,即使是匀速圆周运动,也存在一个加速度,大小为 v^2 / r,方向指向圆心

Scaling back the speed by a factor of 28 leaves you where you were, dragwise, because the square root of 800 is somewhere around 28.

FORBES: Cruising Altitude: Minus 400 Feet

McLaren's Juan Pablo Montoya was sent to the back of the grid last year when he dropped his speed from 278kph on the previous lap to a mere 86kph on the fast approach to Casino Square.
