1F：推 Eisberg:a=F/m 218.170.47.33 08/03
2F：推 unknown1:有解答可是看不懂... 好像要微分有一点复杂~140.116.141.134 08/04
3F：推 Eisberg:a=F/m+dv/dt 这样? 218.170.39.235 08/04
4F：推 unknown1:不是... F=d/dt(v/(1-v^2/c^2)) 再继续化...140.116.144.124 08/04
5F：→ unknown1:我是不知道继续化要怎麽化~140.116.144.124 08/04
6F：推 Eisberg:将F=d(γmv)/dt 乘上dv/dv140.116.143.178 08/06
