The EJS Falling Body On Rotating Earth 3D model illustrates the trajectory of an object dropped from rest (relative to the rotating Earth) from above any point on Earth's surface. The user can set the initial latitude of the object, the height of the object above (or below) the Earth's surface, as well as the rotational speed of Earth. The motion of the object can be viewed from an inertial reference frame, or from a frame that rotates with the Earth (illustrating the effects of the so-called "Coriolis force" among other things). The simulation can be made to stop when the object hits Earth's surface, or it can allow the object to move through the Earth.
The user can select from a variety of options that control the gravitational and resistive forces acting on the object as it falls. The simulation can also generate plots of the object's longitude (initially assumed to be zero) and latitude as a function of time.
