Cars greatly vary in size, and therefore in mass.
A car's mass may vary in the range of 990 to 2000 kg. 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 is, and vice versa. In fact, the mass and safety of a car are said to be directly proportional, so a 2000 kg car is twice as safe as a 1000 kg car. In special studies, it was found out that in most cases, the numbers of crashes between cars are directly proportional to the difference in masses of the two cars.
