END of changes log

Fling anywhere on the the Canvas to see the gravity demonstration.

Try adjusting the gravity, bounciness and rolliness values to simulate different materials and bodies (earth - 1.5 vs the moon - 0.25)

How it works: 

A Clock Timer is used to update the position of a ball by applying x and y velocities and gravity.

When the ball bounces a bounciness multiplier reduces it's y velocity until it eventually stops bouncing.

When the ball rolls, a rolliness multiplier reduces it's x velocity until it eventually stops rolling.

Nice demo, but my ball mostly just lays there.

I may need to consult with my personal physicist.

Are you flinging the canvas (not the ball itself) in a upward direction?

If the ball doesn't move much, you can reduce gravity and/or increase the FlingVelocityAdjustment value to be more responsive.

If the ball sticks to the bottom of the canvas rather than bounce sometimes that (hopefully) has been corrected with a bug fix in updated version 2 which is attached here and in the Gallery.

Thanks for trying it out!
