Even though NASCAR started as a backwoods unauthorized race to run moonshine, it has today evolved into a sport that is not only entertaining but depends on physics too. The obvious element in the physics of NASCAR is the aerodynamic design essential by these cars in order to achieve top speeds of bordering upon 200 mph with the minimum drag coefficient. But there are other forces involved too such as Newtons Law of Motion and centripetal force.

Newtons Law of Motion states that a body will remain in move unless it is acted upon by some external force. In outer space for example, in the inexistence of gravity, an object will go on forever. So there are forces that resist the movement of a NASCAR vehicle such as draught drag and another known as centripetal force.

Centripetal force should not be confused with centrifugal force. However without getting too technical, you can ponder of centripetal force as a existing force acting perpendicular to the course of the transitional body. Centrifugal force on the other hand is indeed a fictitious force and what we feel as we are thrown outward from a mercurial vehicle is the reaction force.

Centripetal force in the physics of NASCAR is crucial to keeping a car on the track. The tires of the vehicle provision the roughness which is part of the centripetal force. The centripetal force needed to keep the car on the track cannot exceed the square of the speed of the car. To put it in unaffected terms, if the car takes a go around too fast, the wheels leave the ground and an accident occurs. The physics of NASCAR dictates that turns on the racetrack must be banked in order to increase the rubbing (part of the centripetal force) to hold the car.

Another ingredient of physics of NASCAR that serves to keep the vehicle with all tetrad wheels on the track during the race is center of gravity. Center of heaviness is basically the point where you could balance the car on the top of a flag pole (theoretically). Racing vehicles need low centers of load in order to keep the weight occlude to the track. If a vehicle has a high center of counterweight then it can lose control when it hits a circumvent much faster. Think of an ambulance with a high profile patient area. If the ambulance took a bend too fast, it would topple over. But if its profile was not too high, it could take the circumvent faster the center of load is lower.

An ambulance needs the high profile in order to get patients in and treat them but the physics of NASCAR dictate the low center of burden in order to apply more centripetal force and keep it attached to the track on a turn.

Then there is the machining of engine components in the physics of NASCAR that are important for building horsepower with the minimum of friction. You want scraping when it comes to centripetal force but you dont want it inside of an engine. This is why internal engine parts are machined to within very accurate tolerances much more accurately than automobiles for family and everyday use. Why? It is you want to minimize elbow grease inside the engine. When engines torque at these speeds, abrasion is a very dangerous enemy.
