Researchers doing satellite tracking of albatrosses in the Southern Ocean observe a bird maintaining sustained flight speeds of 35 m/s- nearly 80 mph!! This seems surprisingly fast until you realize that the particular bird was flying with the wind, which was moving 23 m/s. What is the bird’s airspeed- its speed relative to the air?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
