11. • A meterstick moves past you at great speed. Its motion rela- tive to you is parallel to its long axis. If you measure the length of the moving meterstick to be 1.00 ft (1 ft = 0.3048 m)-for example, by comparing it with a 1-foot ruler that is at rest rel- ative to you, at what speed is the meterstick moving relative o vou?
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.
