Hello everyone!
i am traying to understan how my car spend the gasoline. First of all, i supoused that the main way that my car spend energy is when it have to brake the inerce. for example, when you are in a traffic ligth, you are at 0 km/h and you have to acelérate to be at 40 km/h. that is easy to calculate whit the cinetic energy equation.
But for my surprise, this energy is very low, my results were that whit 1 liter of gasoline, you can brake to 0km/h and acelerate to 40 km/h, by 60 times, its crazy.(i supused that the efficience of my engine to convert the energy of the gasoline is 20%).
After of that, i think in the wind resistence. I have make the calculous and for a velocity of 40 km/h whit a good shape car, the energy is even lower that the before case.
I dont know if i am makeing a mistake, or if i cant recognise a important force.
pd: im from Argentina, im not a good english speaker, i hope that you can understand me :)
good week!
