定律

It follows of the principle of the relativity that Newton's second law of motion, although fundamental i n classical mehcanics, only has an approximate and by no means complete validity.

personal version：牛顿第二运动定律关于相对性的原则，虽然这是经典力学的基础，但是也毕竟是大概的并非完全正确。

Newton's second law of motion describes force. It says force equals the mass of an object, multiplied by the change in speed it produces in an object.

第二定律：F=ma，物体上的外力=物体质量*加速度，就是说物体的加速度，与施加在该物体上的外力成正比，定义了物体的质量就是物体惯性大小的量度。

The gas flow is determined by local average Navier-Stokes equation, the motion of individual particle is obtained by solving Newton's second law of motion, particles collisions are taken into account.

气相流动通过求解局部平均Navier-Stokes方程获得，通过求解牛顿第二定律得到颗粒的运动，同时考虑颗粒之间的碰撞。

To simply thd research process, they isolate the individual objec from its surroundings, and describe its performance in thd time and space domain with linear continuous-variable epuations, arriving at a deterministic analysis, such as Newton's Second Law of Motion and the Epuation of Moving Body.

为了简化研究工作，先把研究对象孤立起来，使之从其所处环境中分离出来，再把它的性能用线性连续数学公式在其所处时空领域中进行描述，得到确定性的分析，例如牛顿的力学定律、运动的方程式等。

Morse potential function was employed to describe interaction forces, and coupling followed Newton's second law of motion. A Gear's predictor-corrector algorithm was used to calculate molecular positions, velocities and accelerations at every time step.

奈米超微粒分子间采用 Morse 势能模型来计算铜原子间的作用力，依循牛顿第二运动定律，并使用 Gear 五阶预测修正法来分析每个步阶的分子位置，速度等物理量。

You can demonstrate Newton's third law of motion with a garden hose.

你可以用一根浇花使用的胶皮软管来说明牛顿的第三运动定律。

And Newton's third law of motion.- See?

牛顿第三运动定律-知道了吗？
