A motion detector is mounted on the floor, pointing straight up. A baseball is held 8 feet above the motion detector and released. Draw a "Position vs. Time" graph and a “Velocity vs. Time” graph to describe the free-fall motion of the ball (i.e. air resistance is considered minimal and do not consider the time when it hits the detector).
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.
