    Undergrad The final explanation to why kinetic energy is proportional to velocity squared

    Just wanted to say it cannot be first power because not enough. I bother about the topic, I'm still thinking about it and haven't accepted it, to be honest. Sometimes when mathematics goes too far I loose the touch of reality. It's my limit. Alberto

    Undergrad The final explanation to why kinetic energy is proportional to velocity squared

    We all know from reality that a car has much more than a double damage when it crashes at 100 km/h instead of 50 Km/h. So speed must be considered more than first power. Let's choose second power: it works! So why don't accept it?
