What would be the best way to plot points in a projectile motion simulation like the one seen here: http://phet.colorado.edu/en/simulation/projectile-motion

I know they use a thread.sleep() method to pause drawing after some fixed time, but how is the line actually being drawn? Is it from an external java plotting library or simply using paint in Swing?

Neither, as it's written in Flash :-)

If you want to do this in Java, check out https://coderanch.com/how-to/java/MiceProblem to get you started.

Are you sure? Because if you download, it comes as a jar file.

Why don't you go ahead and inspect the jar file?

You can use the projectile motion equation to draw it

Don't get me started about those stupid light bulbs.
