A car moves downhill starting from rest and moving at a constant acceleration covering a certain distance in 6 s. Another car, starting from rest, moves in the same direction with the same acceleration for only 2 s. How is the displacement of the first car different from the displacement of the second car? one-third as large three times larger one-ninth as large nine times larger 1/√3 times as large
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.
