您要查找的是不是：
- The rate of change of momentum is proportional to the imposed force and goes in the direction of the force. 物体的加速度跟物体所受的外力成正比，跟物体的质量成反比，加速度的方向跟外力的方向相同。
- The impulse object applied by resultant force is equal to the change of object's momentum, this rule is called theorem of momentum. 这表明:物体受到的合力的冲量等于物体动量的变化量。这个规律叫做动量定理。
- The rate of change of momentum of a body is proportional to the impressed force and takes place in the direction of that force. 一物体动量的变化率与外加力成正比，并与外加力的方向一致。
- A brief dynamic event consisting of the close approach of two or more particles,such as atoms,resulting in an abrupt change of momentum or exchange of energy. 碰撞一个包括两个或两个以上粒子，如原子的高度接近而迅速改变动量和能量的短暂动态过程。
- A brief dynamic event consisting of the close approach of two or more particles, such as atoms, resulting in an abrupt change of momentum or exchange of energy. 碰撞一个包括两个或两个以上粒子，如原子的高度接近而迅速改变动量和能量的短暂动态过程
- The change of the moment of momentum of a system of particles with respect to the center of mass only involves the external forces acting on the system, not the internal forces. 质点系相对于质心和固定点的动量矩定理，具有完全相似的数学形式，而对于质心以外的其它动点，一般并不存在这种简单的关系。

- I noticed a swift change of expression in his face. 我注意到他脸上的表情很快地变化。
- The game of momentum trading appears deceptively easy. 动力交易看起来似乎简单。
- She knew with a change of scene she would soon buck up. 她知道环境一改变她将快乐起来。
- If we are to avoid defeat we need a change of leadership. 我们要避免失败的话，就要换掉领导人。
- I need to tone up with more exercise and a change of diet. 我需要加强锻炼和改变饮食来增强休质。
