    Undergrad Why does kinetic energy increase seem to give free energy with relative velocities?

    I suspect your response is that it says at face value; you didn't read it.

    Undergrad Why does kinetic energy increase seem to give free energy with relative velocities?

    I still don't get this and most answers all over kind of miss the point and just kind of recite without really explaining. Here's the dilemma. Yes, kinetic energy grows exponentially with speed. So a 1kg object changing from 0 to 1m/s increases by .5J. And from 4 to 5m/s increases from 8J to...
