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.
