牛顿第二运动定律讲的是：物体的动量随时间的变化率与受力成正比。或者可以说物体的加速度变化与受力成正比，与质量成反比。牛顿第二定律说明了力是物体运动状态发生变化的原因，与牛顿一、三定律一起作为经典力学的基石。牛顿第二定律适用于宏观低速运动的物体。微观物体应当用量子力学描述，高速物体应用相对论描述。
Newtons Law of Motion In subject area: Engineering Newton's laws of motion state that the force applied to a system may be equated to the rate of change of momentum of the system, in the direction of the force. From: Mechanical Engineer's Reference Book (Twelfth Edition), 1994 About ...
Finding out about and then understanding the forces acting on a moving object, based on a description of the change in motion of this object, is an important part of the conceptual understanding of Newton's law of motion. Using Hempel's deductive-normative model for scientific explanation, we...

牛顿第三定律说的是：相互作用的两个物体之间的作用力和反作用力大小相等，方向相反，作用在同一条直线上。牛顿三大定律最早由艾萨克·牛顿（Isaac Newton）于1687年在他的巨著《自然哲学的数学原理》中提出，是经典力学的基石，在经典力学中具有普适性。 牛顿第三定律继承了前人对动量守恒定律的研究。动量守恒定律...
牛顿运动定律是经典力学的基础，由艾萨克・牛顿在 1687 年出版的《自然哲学的数学原理》一书中提出，包括牛顿第一运动定律、牛顿第二运动定律和牛顿第三运动定律。具体如下：牛顿第一运动定律：任何物体都要保持匀速直线运动或静止的状态，直到外力迫使它改变运动状态为止。该定律明确了力是改变物体运动状态的原因，...

The law proposed by Sir Isaac Newton that expresses the force of gravitational attraction between two bodies as a function of their masses and their distance. Expressed mathematically, F =Gm1m2/d2where F is the force in Newtons, m1and m2are the masses of the bodies in kilograms, G is the...
