    在速度v遠小於光速c時,物體質量m幾乎等於靜止質量m,但是當­v逼近光速c時 ,m就會急速暴增,逼近無窮大,這也說明了超越光速的運動是不可­能的.

    f=ma是用在力的轉換跟能量是兩回事,而且a是加速度不是速度

  • 我突破光速了 我是從2020年來的

  • made in china mutha fucka

  • shock wave occure due to rapid increase in pressure and density, it usually at point of maximum thickness and it accelerate to sonic speed as it reach maximum thickness point if airspeed close to speed of sound.

  • 飛行員表示: 幹 要墜機啦!!(彈跳

  • 阿就追上自己的聲音

    不過還真帥!

  • @b8904311 多吸收點知識吧講到音爆(sonic boom)前,要先理解的是能量震波(shock wave),

    大家都知道物體在大氣裡移動時需要排開周邊空氣,

    排開的空氣因為擠壓到週邊的空氣形成波動(wave)來傳遞能量­,

    而當物體運動速度超過音速時(在大氣及常溫中大約是343 m/s,也就是一馬赫),

    因為週邊空氣無法應付及時的變化,

    所以很多個波動(wave)就會堆積在一起,

    這些堆績而結合在一起的波動因為能量的疊加而形成能量震波(sh­ock wave),

    能量震波威力很強,

    所以一般戰機在操演超音速飛行時,

    都需要飛到至少離地面兩萬公尺(平流層)。

  • @mobius797 安安你動畫看太多了

  • 一個冇實驗証明的推論==

  • Best sonic boom video.

  • 只要滿足條件就能產生那個白霧,雖然是要夠快,但不一定要超過音­速

    超過音速時會產生強烈破壞力的衝擊波,那種距離那些觀眾會全掛

  • 說不家多拉A夢的時光機也是光速行的
