9 2. During the last second of its free fall a body covers part of the total 25 distance traveled. Free fall acceleration is g = 10 m/s?. Find: (1) the height h from which the body falls; (2) the duration of falling. A) 100 m; 4 sec. B) 125 m; 5 sec. C) 150 m; 6 sec. D) 175 m; 7 sec.
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.
