The velocity of a free falling object is given V = √√2gh where Vis velocity (in meters per second), g is acceleration due to gravity (in meters per second squared), and h is the distance (in meters) the object has fallen. The value of g depends on which body/planet is attracting the object. If an object his the surface with a velocity of 30 meters per second, from what height was it dropped if you are on Earth where g = 9.81 m/s²?
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.
