A particle moves along one dimension with a constant acceleration of 3.45 m/s2 over a time interval. At the end of this interval it has reached a velocity of 10.2 m/s. (a) If its original velocity is 5.10 m/s, what is its displacement (in m) during the time interval? m (b) What is the distance it travels (in m) during this interval? m (c) A second particle moves in one dimension, also with a constant acceleration of 3.45 m/s2 , but over some different time interval. Like the first particle, its velocity at the end of the interval is 10.2 m/s, but its initial velocity is −5.10 m/s. What is the displacement (in m) of the second particle over this interval? m (d) What is the total distance traveled (in m) by the second particle in part (c), during the interval in part (c)? m

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.
