This kinematic motion situation in mechanics is a dynamic sketch of an object falling in a moving elevator. This sketch requires Geometer's Sketchpad to run it. The sketch shows the object falling from the ceiling of the elevator as the elevator rises or falls. It calculates the position and speed of the elevator and of the object as time passes. The user can control the height, initial speed and acceleration of the elevator. You must have Geometer's Sketchpad to use this sketch.
