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.
![A cyclist riding in a straight line has an initial velocity of 3.5 m/s, and accel-
erates at - 1.0 m/s² for 2.0 s. The cyclist then coasts with zero acceleration
for 3.0 s, and finally accelerates at 1.5 m/s2 for an additional 2.0 s.

(a) What is the final velocity of the cyclist?
(b) What is the average acceleration of the cyclist for these seven seconds?
Calculate the desired quantities, as well as draw the v-versus-t graph and show
the same quantities as a result of graphical calculation.
