Free Fall 3D

Free Fall 3D simulates the same physics as the Free Fall model but with a 3D View of the model's data.  The ball falls with constant acceleration g=-9.8 m/s2 in the z direction.  Click-dragging on the ball changes its height but leaves its velocity unchanged.  The reset button stops the animation and sets the initial conditions to y=1.8 and vy=0.  See the Free Fall model for a description of this model is implemented in Ejs.

Note:

This simulation was created by Wolfgang Christian using the Easy Java Simulations (Ejs) modeling tool. You can examine and modify this simulation if you have Ejs installed by right-clicking within a plot and selecting "Open Ejs Model" from the pop-up menu.
