Newton’s Cradle Shows Physics in Motion

Written iPhone App Review

Price: Free    Score: 7/10    By Shaun CampbellNewton's Cradle Pro

A simple yet amusing app, Newton’s Cradle for the iPhone simulates the classic desktop toy.

Although only a novelty, the Newton’s Cradle does also demonstrate some important concepts in physics, namely conservation of energy and momentum.

Newton’s Cradle was developed by Enabled Solutions and features a 5-ball cradle that responds to both touch and tilt control. You can select any number of the balls using your finger and then lift them to a desired height before dropping them. Tilting the device will directly affect the behavior of the balls through ‘gravity’.

There isn’t really any other options or features to discuss – there’s not much to Newton’s Cradle – but it does what it set out to do, and it does it for free. A special Valentines Day version is currently available for a limited time for all the romantic physics geeks. The balls are replaced with little hearts you can write a message on. Kind of pointless if you ask me.

Newton’s Cradle requires the 2.2.1 software update and is compatible with both the iPhone & iPod Touch
