When you turn the front wheels to the right for example, your car will tend to continue in its original forward direction. However, there is friction between the wheel and the ground that prevents it from continuing in the forward direction. But if we are turning slowly, the wheel is not sliding against the ground (sliding along the axis of rotation of the wheel). Hence we should not be causing kinetic energy loss through kinetic friction. However, when the car comes out of the turn, it is inevitably much slower. My question is, where does the original kinetic of energy of the car go if there was no kinetic friction? All of the above assumes turning at the same height with no change in grav. potential energy.
We can assume that this is happening in a vacuum with no air resistance. With standard gravity. The car turning in such a way that it is not sliding. Also assume that the car engine is off so take away the complication with idle engines. Also assume that the car transmission has a differential so the two wheels can spin independently at different rates.
