把
①力的作用是相互的.同时出现,同时消失.②相互作用力一定是相同性质的力 ③作用力和反作用力作用在两个物体上,产生的作用不能相互抵消.④作用力也可以叫做反作用力,只是选择的参照物不同 ⑤作用力和反作用力因为作用点不在同一个物体上,所以不能求合力.
翻译成英文.不要网络上的直接翻译,谢谢（越快越好!）
再加一个：自然界中任何两个物体都相互吸引，引力的方向在它们的连线上，引力的大小与物体的质量m1和m2的乘积成正比，与它们之间距离的r的二次方成反比。

Answer 1

1.forces are mutual.At the same time appear,disappear at the same time.
2 .the nature of interaction must be the same role in
3.action and reaction forces on the two objects,the role can not cancel each other out.
4.force can also be called reaction,just choose the reference
5.Action and reaction for different point not on the same object,so can't together.
Any two objects in nature are attracted to each other,the direction of gravity on their attachment,the size of the gravity of the m1 and m2 to the mass of the object is directly proportional to the product,and they r of the distance between the two inverse proportion.
