The Zero Gravity Research Facility (for more information you can check out their homepage at the URL http://zeta.lerc.nasa.gov/facility/zero.htm). At the Zero Gravity Research Facility at NASA Lewis Research Center the main facility is a tower which allows to drop something from a height of 145m. a) How long can an object be in free fall if it starts falling from the top? b) What is its speed just as it reaches the catching device at the bottom? c) When caught, the object experiences an average deceleration of 25g as its speed is reduced to zero.
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.
