Shown below are six POSITION vs. TIME graphs. Let EAST be the positive direction. Identify all the graphs that show an object MOVING EAST THE ENTIRE TIME. Then identify all the graphs that show an object MOVING WEST THE ENTIRE TIME. Finally, identify all the graphs that show an object MOVING AT A CONSTANT VELOCITY THE ENTIRE TIME. MOVING EAST the whole time MOVING WEST the whole time MOVING AT CONSTANT VELOCITY the whole time 0 ■ U POSITION vs. TIME GRAPHS ✔ ■ H ■ x x
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.
