But a growing number of legal cases claim Toyota knew for a long time about the sudden acceleration issue with other vehicles.

Now, gravity, well force, is equal to mass times acceleration, g and the acceleration due to gravity is g.
是重力,等于质量乘以加速度,由重力导致的加速度是。
Therefore, when you divide by the mass to get the acceleration, the response of different bodies is inverse to the mass.
因此,当你拿力除以质量得到加速度时,不同物体的加速度与质量成反比
"Buildings in Jakarta are built to withstand horizontal acceleration of about and this earthquake which just happened yesterday maybe about five percent of gravity,"

You will learn in 8.02 that if you have a charged body changing direction, that constitutes an acceleration.
你们将在8。02中学到,如果一个带电体改变方向时,产生一个加速度。
The National Highway Traffic Safety Administration has linked more than 50 deaths to the unexpected acceleration problems -- a safety issue Toyota has blamed on floor mats and sticky gas pedals.

And bathing inside the inner ear fluids where they become stimulated by sound waves and acceleration forces.
毛细胞悬浮在内耳液中,接受声波和其它外力的刺激。
Gates' stressed that,in any case, he saw no cause for a slowdown in the pace of U.S.troop pullouts, but that any acceleration, would necessarily depend on an assessment of the situation by U.S.Commander Ray Odierno.

To understand India's economic growth acceleration you really have to go back about 25 years.
想要了解,印度经济的腾飞,你真的必须回过头,从25年前观察起。
I think there's at least and I'm not going into any specifics but I think there's at least some chance of a modest acceleration But,because of the way General Odierno sees things going, that remains to be seen,".

Why should the amount by which you're attracted to the Earth be also a measure of how much you hate acceleration?
为什么物体受地球引力的大小,恰好能衡量物体加速的难易程度呢
So, a massless body cannot have a net force on it, because the acceleration of the rope cannot be infinite.
所以没有质量的物体不会受到力,因为绳子的加速度不可能是无穷大
It's useful to have the average acceleration, which you can find by taking similar differences of velocities.
平均加速度也是很有用的,你可以用类似方法,取速度的变化量求出来
When you're falling to the surface of the Earth, you are describing a problem of constant acceleration.
当你讨论下落问题时,你在描述一个加速度恒定的问题
And know intuitively that if they move together, they will behave like an object of mass 5 and the acceleration will again be 2.
凭直觉认为既然它们一起运动,那么它们就相当于一个质量为 5 千克的物体,然后我们可以算出加速度为 2
And, you know acceleration means either change of speed or change of direction.
你知道加速度意味着,不是改变速度就是改变方向。
It says that, "If a body has an acceleration, then you need a force and the relation of the force to acceleration is this thing."
它是这么说的,"如果一个物体有加速度,那么你需要有一个力,力和加速度的关系是这样的"
He just said whenever there's an acceleration, it's going to be due to some forces and it's your job to find what the forces are.
他只说过只要有加速度,就说明有力的作用,你们的任务是要找出这些力
One is inertial mass, which is how much you hate your velocity to change, how hard you resist acceleration.
一个是惯性质量,它反映了物体速度改变的难易程度,即保持加速度的难易程度
But the acceleration it produces on the elephant and on the mass, are in an inverse ratio of their masses.
但这个力使大象和物体产生的加速度,与它们的质量成反比
You cannot have a spring pulled only at one side, because then it will then accelerate with infinite acceleration in that direction.
你不可能对弹簧只施加一边的拉力,因为那样的话弹簧就会以无穷大的加速度加速,就在这个方向上
Now I can measure that, because I pull it by one centimeter and I find the acceleration it exerts on a known mass.
现在就能测量这个力了,因为把弹簧拉伸 1 厘米,我就知道它让一个质量已知的物体产生的加速度
Simply knowing the acceleration is not enough to tell you where it was at the initial time.
仅仅知道加速度是,不足以告诉你它在初始时刻的位移的
So, when you divide by the mass to get the acceleration, you get the same answer.
因此,当等号两边除以质量来求加速度时,结果是相同的
A limited class of problems is one in which the acceleration is just a constant.
在这类有限的问题里,加速度均为常数
As you start on the top and go down, your acceleration is negative.
当你在顶楼准备下降的时候,你的加速度是负的
Then you guys know, you just told me, acceleration is -9.8, We call it "minus" because it's accelerating down and up was taken to be the positive direction.
然后你们都知道,你告诉我,加速度是-9.8,我们取负号是因为加速度方向朝下,而正方向为竖直向上
What's your plan for measuring acceleration if some little thing is moving?
如果某个小物体在运动,你要如何测量加速度
Can you tell me why I'm sure the Earth has an acceleration?
你能告诉我为什么我确信地球有加速度吗
Newtons acting on 2 kg, gives you an acceleration of 2.
牛的力作用在 2 千克的物体上,那么其加速度大小就是 2
