I will research this because a car that is bigger, means that it will be heavier which could lead to the car being slower than a car that is smaller. In addition, if the car is too small, the person won't be able to fit in and even if it does, the person inside could fall out because of the force that is put in at the back of the car, which cause the car to flip as well, which could cause an accident. As a result, the size of a car is very important as it can change the cars' speed. Due to this, the question "How does the size of the formula one car affect its performance?" is important as I will need to design the car that is the most efficient size, so that it isn't too small or too big. In addition, this is important to know as well because if the racing car is too slow, then the person that will be driving the car won't be able to win the race. Due to this, not many people will be wanting use this car.
