Planet Gravity isn't just about gravity anymore. Select a planet to get a scrolling fact about that planet on the display. This app is a twist on the Newton’s cradle balance balls. The pendulum balls collide just like the real set and you can select other planets to use that planet’s gravity. How does the pendulum swing with different gravity?
