描述

This great App shows how forces affect objects in space! Drop objects into the scene and put forces in the scene to affect the objects!

Demonstration of gravity, anti-gravity and vortex forces with images dropped in to the screen that get attracted to the forces when the users touches. The user can select Vortex, Gravity or Anti-Gravity forces and watch the fun in this physics simulation!

Vortex will cause the objects on screen to rotate around. The user can increase or decrease the vortex forces on screen so the rotate left, stop or rotate right. The user can also increase or decrease the gravity forces on screen.

Gravity will attract objects on the screen. Anti-gravity will repel objects on the screen.

The user can increase or decrease the mass of the colored squares on screen by swiping up or down. Reset color mass to defaults by swiping left.

Clear the screen by swiping right.

Show or hide forces by pressing the buttons on the top of the screen.

Special Thanks to NASA for the public domain images used for the Space pictures!
