Uniform Motion Two cars leave an intersection at thesame time. One is headed south at a constant speed of30 miles per hour, and the other is headed west at aconstant speed of 40 miles per hour (see the figure). Builda model that expresses the distance d between the cars as afunction of the time t.[Hint: At t = 0, the cars leave the intersection.]
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.
