Hi Guys If you type that thread title into Google images, you get plenty of examples describing bouncing ball movement, but I’d like to know what a ball bouncing up and down on the same spot looks like. Are there any examples of that? I’m after 180 degrees of amplitude data essentially so a program could simulate a convincing bouncing ball on a 2D screen that never loses energy. I’m just not sure if that will look sinusoidal or actually circular. Cheers, Brek.
