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.
ground?
b) What is its final velocity?
2. A pebble was dropped from the window of a building, 80 meters above the ground. a) How many seconds will
it take the pebble to reach the ground? b) How fast is it after 2.0 seconds? c) When will its velocity be 25 m/s?
3. A stone is tossed upward at the moment a ball is dropped from a height of 25 meters. The stone’s initial
velocity is 25 m/s. At what height will the two meet? In how many seconds.
4. A ball is thrown downward with an initial velocity of 20 ft/s. a) How fast is it moving 2s later? b) How far
does it fall in these time ?
