Newton’s three important laws
牛顿的三个重要法律
Things that move obey certain laws. Three important laws of motion were established by Isaac Newton
遵守一定的规律移动的东西.三个重要运动定律了艾萨克·牛顿
NEWTON Ⅰ: INERTIA(惯性定律)
牛顿Ⅰ:惯性(惯性定律)
Newton’s first law of motion seems simple: Objects at rest tend to remain at rest, while moving ones continue to move at a uniform speed in a straight line---unless acted upon by an outside force. This resistance(阻力) to change is called inertia, and it explains a lot of everyday experienced no matter where you happen to live.
牛顿第一运动定律似乎很简单:对象在休息倾向于保持静止,运动时的人继续在匀速在一条直线上——如果受到外力的作用.该电阻(阻力)来改变被称为惯性,这说明了很多的日常经验,无论你在哪里发生的生活.
One is that when the car or airplane you’re in begins to move, your body is pushed back against the seat. That is, it tends to remain at rest despite the forward-moving force of the vehicle transferred to you through the seat. Another aspect of this law shows that the normal courses for freely moving objects is a straight line. That explains why, when you whirl
一个是,当汽车或飞机你在开动的时候,你的身体是推迟在阀座上.那是,它往往保持静止尽管forward-moving力的车辆转让给你通过座位.这一法律的另一个方面显示正常课程的自由移动的物体是一条直线.这就解释了为什么,当你试
something around your head---such as a ball on a string---and then let it go, the ball flies straight. It neither keeps circling your head nor does it move off in a sweeping
在你的头上的东西——比如一个球- - - - - - -一个字符串那就让它去吧,球直飞.它既保持著头也不朝一个空前的

NEWTON Ⅱ: F=MA
牛顿Ⅱ:F = MA
Newton’s second law relates the amount of force needed to move an object to the object’s mass and tits acceleration(加速度).
牛顿第二定律的数量与力量需要把一个对象到对象的质量和山雀加速度(加速度).
Push a child in a swing, or ride a planet around the sun, and you’re using Newton’s second law of motion, which states that whenever you want to change the speed or direction of something, you have to apply an appropriate force. The bigger the mass or the larger the intended acceleration, the greater the necessary force. This law’s formula allows engineers to calculate what’s required to launch a jet fighter
把一个孩子在秋千上,或骑行星绕太阳,你正在使用牛顿第二运动定律,该定律,无论你想改变速度和方向的问题时,你必须运用适当的力量.更大的群众还是较大的预定加速度越大,所需的力.该法律的公式计算出工程师需要推出一个喷气式战斗机
