18 Feb 2010 – New iPhone App simulates Newton’s Cradle – The Physics Desk Toy

*Update:  AppReview Live:  5 Stars!!!  Here is a quote:

“This app is pretty cool.  In fact it reacts exactly like the real thing.  The developer has done a wonderful job imitating the physics of the Newton’s Cradle.  In fact it is so realistic that if you turn your phone upside down you may get the balls stuck up top.  If you swing the balls at the wrong point you may get them tangled. “

Newton’s Balls is a Newton’s cradle simulator for the iPhone and iPod Touch, which demonstrates kinetic energy and conservation of momentum.  But more than that, it’s fun.  You can download it here.
