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.
A car's mass may vary in the range of 990 to 2000 kg. However, a typical car may require more than 770 kilograms of steel, 180 kilograms of iron, 110 kilograms of plastics, 80 kilograms of aluminum, and 60 kilograms of rubber, as well as, less significant amounts of different materials. The total mass of an average car may be about 1500 kilograms. One of the most important things about the mass of a car, is the fact that the heavier it is, the safer it for the occupants, and vice versa.
