Wheelbase is a term used to describe the distance between the centers of the front and rear wheels of a vehicle. It is a horizontal distance that is measured in millimeters or inches, depending on the region. The wheelbase is not equal to the overall length of the vehicle, which is measured from its front and rear ends. The wheelbase is an important factor to consider when choosing a vehicle, as it affects the vehicles stability, handling, and ride quality. The longer the wheelbase, the more stable the vehicle is, but it may be less maneuverable. On the other hand, a shorter wheelbase may be more maneuverable, but it may be less stable. The wheelbase is related to the force on each pair of tires by a formula that takes into account the mass of the vehicle, the distance from the center of mass to the front and rear wheels, and the gravity constant.
