Air Resistance of a Car

The resistance of an environment significantly influences the movement of cars, trucks and sports cars. The shape of the air flow around the cars' bodies is used to compare their aerodynamic properties. To state a drag of an individual body, a variable called **a drag coefficient** (*C*) was established. Sports cars have a coefficient *C* less than 0.3. For passenger cars, the coefficient is higher (*C*= 0.34), and for trucks even higher.
