On a hot summer day in the state of Washington while kayaking, I saw several swimmers jump from a railroad bridge into theSnohomish River below. The swimmers stepped off the bridge,and I estimated that they hit the water 1.5 s later. (a) How high wasthe bridge? (b) How fast were the swimmers moving when theyhit the water? (c) What would the swimmers’ drop time be if thebridge were twice as high?
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.
