I wonder what is better to achieve the best possible traction for good acceleration: – much weight – less weight Suppose I have unlimited power available, what accelerates better, a vehicle with 1000kg, or one with 2000kg? In the heavier car, the pressure on the press would have to be higher, but also the mass to be accelerated. What is better now and how can one explain this physically? (as I said, purely theoretically with the assumption that infinite vie l power is available, but which must be transmitted via the wheels)
