Concept explainers

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.

An athletic 6ft tall Human walks in a straight line between point A and point B on a flat surface counting every step untill he has covered the distance between points which is precisely 5 kilometers. The journey takes him 1 hour, so he knows that his body moved at a consistent speed of 5kmph. The Human is then shrunk to a perfectly scaled 3mm tall duplicate and is instructed once again to walk a straight line ( under identical conditions ) keeping the same pace and repeating the exact same number of steps that he took at 6ft tall. Question - Is it true that the tiny 3mm tall Human has traveled at a speed 5kph and traversed 5km of distance ?
