You make a wish and drop a coin into a wishing well. The top of the wishing well is 5.0 m above the water surface. When the coin hits the water surface, it sinks to the bottom of the well with a constant velocity equal to the velocity with which it hit the water. If it takes the coin 3.0 s after it was released to reach the bottom, how deep is the well?
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.
