The physics engine that comes with Corona Game Edition is an incredibly powerful and easy to use tool. In this tutorial, we will cover the completion of a rudimentary basketball game using this exciting technology

The first thing we do (as in many programs) is get rid of the status bar at the top of the screen. Next, we make the necessary require statement for using physics and store the result in the aptly named "physics" variable. Things become more interesting in the next few lines. In line five, we set the gravitational acceleration. Typically, gravity is set to 9.8 m/s*s in the positive y-direction, but in this instance we want to make gravity pull in the positive x-direction because the application will have a landscape orientation. Furthermore, we set the scale to 80 pixels per meter. This number can vary quite a bit based on the size of the objects in your application, and you may have to play around with it to give your game the correct feel. I chose 80 px/m because I want to fit about 15 feet of vertical space on the screen. Knowing that, it's just a simple matter of unit conversion to get a value.
