Someone said the following and it just doesn't sit right with me. How do I effectively tell them what's wrong here? " It applies to physics the same, as can be seen with the Kinetic Energy Formula Ke = 1/2MV^2 http://www.edmunds.com/car-reviews/...mustang-boss-302-vs-2011-ford-mustang-gt.html As we can see by the track times above, it takes roughly the same time to accelerate from 0 - 30, as it does from 30 - 60 miles per hour. http://www.frontierpower.com/library/makingsense.htm From this graph we can see that fuel consumption of an internal combustion engine is quite flat. So, with this in mind, we can conclude that the same amount of fuel was used to accelerate the car from 0 - 30 as it does 30 - 60. Since kinetic energy is a product of velocity... Where is this extra energy coming from? Either the car should take 4 times longer to achieve the velocity, 4 times the fuel, or our cars gain 400% efficiency every time you double the velocity. “Today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. ” ― Nikola Tesla "
