Getting started with physics

Phaser uses multiple physics engines that you can choose from to implement realistic simulations in your game. For simplicity's sake, we're only going to be concerned with the wrapper Phaser gives us.

Check out some examples of what you can do here:

For reference, Box2d is the most popular open-source 2D physics engine that has been ported to almost every language. We won't get into it now since using Phaser's built-in library is easier.
