The graph shown below is the velocity, in cm/sec, of an object moving along the x-axis between times t = 0 and t = 5 seconds. Positive velocity indicates motion to the right. 2 -3 v(t) 3 5 t (a) At time t = 5, where is the object in relation to its starting position? O The object is right of its starting position. O The object is at its starting position. O The object is left of its starting position. (b) At time t = 1, how far is the object from its starting position? cm (c) How far has the object traveled between t = 0 and t = 5? cm
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.
