曾经有人比喻过:汽车如同和平时期的炸弹,交通事故如同没有硝烟的战争。汽车与炸弹,在物理学上都有一个共同具备的东西,那就是能量。炸弹的能量来源于化学反应,并且是在爆炸的瞬间释放出来;而汽车的能量来源于汽油的燃烧,并表现在行驶速度上——汽车速度越快,它所蕴涵的能量就
Someone once said: cars are like bombs in peacetime. Traffic accidents are like no smoke war. Cars and bombs, in physics have a common thing, that is energy. Bomb energy comes from chemical reactions, and is released at the moment of the explosion; and the car’s energy comes from the combustion of gasoline, and showed in the driving speed - the faster the car, the energy it implies
