Hi Claudio, Realistic physics means that the car in the game will react properly to real world physics and mechanics. For example, think of what happens when you are driving down the strait away at 200 MPH and hit the breaks. Does the car just stop? No, it will slide and skid along ways down the track before it comes to a stop. The only way you can accurately predict how far it will slide is by calculating the known laws of physics applied to that car. For example, in algebra we were all taught the expression distance equals rrate times time which will calculate the distance an object will travel at a given rate in a specific amount of time. However, we don't know the actual rate of the car when the breaks were applied. So we have to use physics to figure how much friction, counter force, was applied by the breaks to calculate the rate of deceleration. If a developer wants to go by the book on physics he is going to want to consider things like the weight of the car, the weight of the driver, the condition of the tires, and so on. All of those factors could come into play. Take the tires for example. On the average family car there are all purpose tires with thick tread for use in snow, dirt, mud, bla. The idea is to get friction and traction in various weather and driving conditions. Though, on a Nascar sports car they use a bald tire. The reason for this is that the bald tire will offer less resistance, less friction, on the track while racing. As a result that same bald tire would offer less counter force when pressing the breaks than your average all purpose tire. Anyway, once you figure out how much counter force was applied you can use that to get the amount of deceleration. Which in turn can be used to reduce the rate of the car. Once you know the current rate you can pass that off to your distance equals rate times time equasion to find how far the car will slide down the track.
