Since a bell-clapper vibrated at regular intervals of time, it can be used as a timing device. With the ald o carbon paper and ticker-tape, the position of an object relative to time can be determined. Figure 1 shows ª sample of a tape drawn through the bell-clapper. a b Figure 1. During what interval was the velocity constant? Between (& D During what interval was the acceleration greatest? Instead of using a time unit of only one vibration, we might use five vibrations, a penta-tick. Scm. What is the distance traveled during the first penta-tick? If we know distance and time, then we know the speed. Therefore the average speed traveled during the first penta-tick is during the second penta tick is 10

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.
