Well, ScottD, the ball of rubber will bounce higher in free air, of course. In a vacuum, neither will bounce at all.
-
no doubts its rubber, yeah its rubber ball, coz glass ball cannot absorb the potential energy as compared to rubber ball.
-
Is this theoretical or a trick? Won't the glass break? Or is that the answer you're hoping for so you can give us the right answer? :)
-
rubber glass will shatter
-
The glass ball is not gonna bounce at all! The rubber one will bounce really high, especially if it's a superball!
-
That depends on just what the floor is made of!
-
Glass. Put a twist off cap back on a beer bottle that thing will bounce. And it also depends on what kind of rubber
-
A quick answer, with out a great deal of thought, would be that, it's dependent on the yeilding nature of the surface they are propelled against. If the opposing material is hard and unyeilding, solid glass doesn't absorb energy like the rubber, and that energy would have to manifest itself in someway, so I'm guessing glass. That's only if the surface is extremely hard, and both the glass and rubber, have the same amount of energy applied to motion.

Wait, you have glass balls?lol
-
The glass ball
-
Depends on the size, weight of each ball and the atmosphere, the surface used for the bounce, that is assuming equal force used to propel them and equal distance from the bounced surface.
-
Glass.The coeficient of restitution is more in case of glass as compared to rubber.

Ok, let's assume that I understood your question. In ideal conditions, two balls, one rubber, one glass, equal in mass are dropped from the same height onto an ideal elastic surface (this means that all energy lost is lost in the ball itself, there is no air, no friction on the surface, nothing but the balls). Assuming you are talking about the rubber which is used in physics (it has constants equal to: static friction (SF) of 1.6, Kinetic Friction (KF) of 1 and elasticity (E) of 0.75 while the glass has constants of SF = 0.9 KF = 0.4 E = 0.96)this rating of the elasticity is what is used to calculate the height of the next bounce, and as the glass is more elastic, it will bounce higher.

glass will bounc higher (but it depends on the rubber
-
a ball of glass

A Goddess lol!!!!!!!!! Hiiiiiiiiiiiiiiiiiiii Scott!!!!!!!!!!!!!!!! So great to see you are still around :):):) Hope all is great!!
