Download the 22 sprites and 23 scripts of "Planet Collision" and open it in Scratch Project Notes
What happens when a small planet is within an asteroid belt. Eventually, the planet will gain mass (size) due to the collisions, and mostly clear its orbit.
In reality, a planet would not be entirely in free-fall, the asteroids would collide too, and all the objects would be affected by gravity. But I suppose anyone who remixes this can figure that out ;-)

interesting. You could add music to your projects, though.
Thanks! I don't normally add sounds because it makes the project lag.
Cool! I never new all these things! I always thought that too many asteroids would result in it disintegrating. What about the asteroids, why don't they grow too? It takes a while for the planet to start growing, but it is worth it. I think I'll let it sit for awhile and see how big it can get.
Thanks! The asteroids don't grow because this is just a basic demonstration. I don't think Scratch has enough memory to do that anyway, but I could be wrong.
(view all replies)Neat! Trying to calculate gravity forces for all those objects would take more processing power than Scratch can provide :)
That's cool...
