If a car has less weight, it will speed up faster and stop faster because the momentum of the car is less than that of the heavier car. A: It is called the power to weight ratio.o. What an object weighs (which is the effect of gravity on the object's mass) does not affect it's speed whether it's free falling or on an incline. On Earth which has an at â¦ mosphere, drag has an effect on the speed of the object.
Hitting an immovable object, such as a wall, the speed of the car would have to be 10-15mph. I suppose the difference would be that hitting the wall would be instantaneous deceleration, whilst hitting another vehicle would give a cushioning effect. Its not really a case of How fast but more a case of how hard. For example an air bag will deploy in the case of a stationary car being hit by a lorry at 5mph.
