The graph shows the displacement-time history for the rectilinear motion of a particle during an 8-second interval. Determine the average velocity vay during the interval and, to within reasonable limits of accuracy, find the instantaneous velocity v when t = 4 s. 8, m 10 8 00 6 4 2 0 0 Answers: 2 4 t, s When t = 4 s, 6 For the whole interval, Vav= V = 8 m/s m/s
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.
