momentum The product of the mass and velocity of an object.
nautical mile A unit of measurement defined as 1852 meters (approximately 6,080 feet or 1.2 statute miles).
Newton’s Laws of Motion Three physical laws that describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.

velocity The rate of change of an object's position with respect to a frame of reference, and is a function of time.
vertical axis Also called yaw axis, is defined to be perpendicular to the wings and to the normal line of flight with its origin at the center of gravity and directed towards the bottom of the aircraft.
