The Physics of a Wheelie

While asking my dad about the physics of cars, he happened to bring up the impressive physics involved in doing a wheelie. After going to many drag races with my dad I've seen many cars do wheelies, but I never really thought how it happened until now. If you don't know a wheelie is when a car or motorcycle is riding on only its back wheel(s) for a short period of time. As shown in this picture when a strong force is applied to the back of the vehicle, by the force of the tire pushing against the road, it creates an equal force applied to the center of mass of the vehicle,and once the moment of this overcomes the force of gravity, the front wheels pop up.
