A bolt is dropped from a bridge under construction, falling 85 m to the valley below the bridge. (a) How much time does it take to pass through the last 23% of its fall? What is its speed (b) when it begins that last 23 % of its fall and (c) just before it reaches the ground? (a) Number i Unit (b) Number Unit (c) Number i Unit
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.
