照我阿sir講,光速下的東西 do not obey Newton Law

接近又會點ga?
其實Relativity 可唔可以用來計古典力學d 數

勁量電芯

繼續離題
我Form 1 o個年 = 99年
當時仲興緊....

離題too

我記得金版係5/6年級果時出ge...

幾有趣....
但點知 dm/dt 係咩

同埋按道理有個Net Force 作用係一件物件....個物件速度會不斷增加......
by F=ma

質量改變
F=d(mv)/dt

你知唔知 要有時光機 回到未來 係要快過光速既 點可能做到出黎呀 同上太空係唔同架 聰明少少ｏｋ？？？唔識就唔好亂插人啦

唉,唔知頭唔知路就唔好出聲啦
當一件物件去到某一個v ge 時候,mass 就會不斷咁加大
by 乜鬼F=ma姐,
讀多幾年phy 先回應啦,睇番你ge chem post 啦!
