the hardness is different
-
Rubber ball made of rubber which makes it jump higher...and it is lighter as well...Marble ball is heavier and it is made of glass if i'm correct..So marble ball won't bounce well
-
the rubber ball is more stretchier than the marble and thus the rubber ball (since its rubber like an elastic band) like an elastic band shoot right back up when you bounce it and a marble is hard and it isnt elastic enough to bounce higher.
-
A rubber ball bounces better than a marble ball because rubber is more bouncy than marble. It sounds like a stupid answer, but that is the reason. As to why rubber is more bouncy ... zoom in and rubber is made of billions of molecules like rubber bands tangled together. Imagine a big ball made of tightly tangled rubber - it will bounce just like a soccer ball. Marble is made of billions of molecules like small rubber balls stuck together with glue. Imagine a big cube of this. It will bounce but only an inch or two. It will tend to flop down.

Because rubber is soft enough to squish, but firm enough to rebound quickly.

I know 2 9 nine year olds who can grasp this: Dexter within his lab and Lio the comic strip child. The kinetic properties within marble are impeded by the solid bondingings within the silicate molecules while the loose structure of bonding within the molecules which compose the complex make-up of the rubber molecules has a greater expanxe of connectivity which provides a much larger tolerance rance for the intrusion of the molecular scpace for invaried intrusions upon the weaker areas of molecular bondage whereby allowing "more give" hence provinging the so called bounce which is experienced when a "super-ball" is bounced. Hence in caveman heavy and tight make no go bounce bounce and loose and elastic make big bouncies

more molecules

It doesn't. It all depends on what surface it bounces on. Either the ball or the surface changes shape. A rubber ball changes it's shape, but a marble changes the shape of the surface it bounces on. And if the change is only temporary, it snaps back to it's original shape, and the ball bounces. But some energy is lost in the process, and the ball bounces lower each time. Generally a hard surface will make a hard ball bounce higher, since they hardly change shape, and they keep more of their energy. So on an ideal surface a marble would bounce higher than a rubber ball, as long as it doesn't break. Check out liquid metal: http://www.liquidmetal.com/media/ball_bounce_DSL.wmv Skrommel
