Learning Goal: To leam to use images of an object in motion to determine position, velocity, and acceleration. Two toy rockets are traveling in the same direction (taken to be the x axis). A diagram is shown of a time- exposure image where a stroboscope has illuminated the rockets at the uniform time intervals indicated. (Elgure 1) Figure < 1 of 1> A 1=0 1=1 1=2 1=3 1-2 The moton of the rocket labeled A is an example of motion with uniform (i.e., constant), O and nonzero acceleration O velocity O positian O time
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.
