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.
![54 In Fig. 28-40, a metal wire of
mass m = 36.9 mg can slide with
negligible friction on two horizontal parallel rails separated by
distance d = 2.56 cm. The track lies in a vertical uniform magnetic
field of magnitude 42.0 mT. At time t = 0, device G is connected to
the rails, producing a constant current i = 9.13 mA in the wire and
rails (even as the wire moves). At t = 61.1 ms, what are the wire's
(a) speed and (b) direction of motion (left or right)?
