通常进行10至15分钟的小跑之后再加速。

Always begin with 10 to 15 minutes of easy running before picking up the pace.

你可以先跑个加速度的一英里来热热身，再加速度跑个一分钟，然后再恢复到一个平缓的速度跑个一分钟。

You can start adding speed by warming up for a mile and then running at a faster pace (breathing heavy but still in control) for a minute and then recovering at an easy pace for a minute.

你将拥有四驱全开，408的马力，再加上4.4秒的百公里加速时间。

You get all-wheel drive, 408 horsepower and a 4.4-second 0-to-60 time.

youdao

Their difference divided by the difference in times is going to be the acceleration.

它们的差值再除以时间的差值,就是加速度

That's how by either balancing the unknown force with a known force or by simply measuring the acceleration as I fall towards this podium and multiplying by mass, you can find the force that exerts on me.

我们既可以让未知力与已知力平衡,也可以只测量我冲向讲台时加速度的大小,再与我的质量相乘,都能求出作用在我身上的力的大小

At any point on the graph you can take the derivative, which will be tangent to the curve at each point, and its numerical value will be what you can call the instantaneous velocity of that point and you can take the derivative over the derivative and call it the acceleration.

在图上的任意一点,你可以进行求导,得到曲线上每一点的切线斜率,所得到的数值,即为该点处的瞬时速度,然后你再求一次导,得出它的加速度
