Why does a car uses more fuel with lesser air in tyres?
Work done =F.d
The Attempt at a Solution
According to me Friction does no work in rolling if the tyre is purely circular. But when tyes are deflated then they are not circular. Due to this friction does negative work on the wheels. Due to this kinetic energy of the car decreases and hence same velocity needs more fuel. Is that correct? Also is there anything else to be considered.
