Yaw is a type of motion of an object around its vertical axis, so that the longitudinal axis changes direction in the horizontal plane. The yaw angle is the angular value between the current longitudinal axis of a moving object, and the direction of travel of the object.
Yaw is a basic movement of an aircraft, ship, or projectile. The basic aerodynamic or hydrodynamic means of changing yaw is the rudder.
