Can you have a positive or negative velocity but a position with the opposite value (negative or positive)? Explain why or why not. (Easy to understand) Can you have zero velocity but a positive or negative position? Give an easy example. As you look at the graph for position, what does the slope of the line for distance vs. time tell us? (hint: Δd/Δt) As you look at the graph for velocity, what does the slope of the line for velocity vs. time tell us? (hint: Δv/Δt)
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.
