Newton the first theorems what acceleration and object being an object accept agrees well with outside force F direct proportion, and the object mass becomes inverse ratio , the acceleration direction and the direction closing an outside force.

牛顿第二定律是物体的加速度跟物体所受的合外力F成正比，跟物体的质量成反比，加速度的方向跟合外力的方向相同。
