5a) Assuming that the cart started at rest at the point x = 0.0 m when t = 0.0 s, what was the position of the cart when t = 4.0 s? 5b) Assuming that the cart started at rest at the point x = 0.0 m when t = 0.0 s, what was the position of the cart when t = 6.0 s? 5c) Wait... No, we were wrong... The cart was actually at the point x = 2.7 m when t = 0.0 s. With this new piece of information, what was the position of the cart when t = 3.0 s? 5d) No wait... That's still not right... The cart was at the point x = 2.7 when t = 0.0 s, but it already had an initial velocity of 1.7 m/s. Now using this information (and that's the last correciton, honest),what was the position of the cart when t = 3.0 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.
