The above diagrams indicate the motion of a ball moving from left to right and subject to one or more forces on various surfaces. Each circle represents the position of the ball at succeeding instants of time. The time-interval between each successive position is the same. The bold arrow indicates the positive direction. Below are various plots of position, velocity and acceleration versus time. In the space to the right of each above diagram, write ALL of the possible plots which may represent the motion shown in that diagram. (Not all the diagrams can be represented by the same number of plots.)
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.
