In Michael Johnson's world-record 400 mm sprint, he ran the first 100 mm in 11.20 ss; then he reached the 200 mm mark after a total time of 21.32 ss had elapsed, reached the 300 mm mark after 31.76 ss, and finished in 43.18 ss. During what 100 mm segment was his speed the highest?
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.
