In vehicle dynamics, what does the "pitch" axis refer to?

The "pitch" axis refers to the rotation around the lateral axis of a vehicle. This rotation involves the tilting motion that occurs when the front of the vehicle moves up or down in relation to the rear. For example, when a vehicle accelerates, the weight shifts toward the rear, causing the front end to rise. Conversely, when braking, the front end dips. Understanding the pitch axis is critical for various performance factors, including handling, stability, and passenger comfort, particularly during maneuvers that require turning or sudden speed changes.
