Routh's rule of inertia

例句：

1. 1. The law of inertia states that objects at rest will remain at rest and objects in motion will continuein motion unless acted upon by an external force.
   惯性定律表明，静止的物体将保持静止状态，运动的物体将继续运动，除非受到外力作用。
2. 2.In the case of a car, for example, if you apply the brakes suddenly, the car will not immediately come to a stop but will continue to move forward until it reaches a point where the inertia of the moving parts is overcome bythe force of the brakes.
   例如，在汽车的情况下，如果你突然踩刹车，汽车不会立即停止，而是会继续向前移动，直到动部件的惯性被刹车力克服为止。
3. 3. The principle of inertia is fundamental to understanding the behavior of objects under gravity or other forces.
   惯性原理是理解物体在重力或其他力作用下行为的基础。
