The reason a golf ball goes as far as it does (Not in my case.), is that it compresses on impact. Two super-balls hitting each other should increase the rebound. Hell, I was alive when they first came out (1967?). We loved them and would bounce them off the big wall that was in our highschool quad. Then, we couldn't stop them and got bored.

"How many does your boyfriend have?"

well the closest thing I have to a "boy-friend" is Cleveland John...so why don't we just ask him.. [img]/images/graemlins/laugh.gif[/img]

No, it's because of the dimples in the ball, which though the air behind, reducing air friction on the ball, thusly allowing it to travel a greater distance.

If two superballs of the same mass colided in mid air, and both where 100% elastic, they would just fall to the ground. But, the chances that they are 100% is very slim, so they would recoil off each other... not in random directions at all... at a slower speed, if you had actuall numbers it wouldn't be hard to work it out.

This is highschool physics stuff :P

How fast were they going when they collided?
I mean if they were each traveling at say 400 MPH, they would explode on impact. [img]/images/graemlins/grin.gif[/img]

Watch a slow mo of a golfball being hit. Never took highschool physics. Too hard. Got my degree in Soc. That way I didn't have to memorize anything. [img]/images/graemlins/laugh.gif[/img] [img]/images/graemlins/laugh.gif[/img]

Hahaha, good stuff then :P I actually have a physics examination coming up soon... *grabs list of 10,948 fomulas*

you're sure about that?
I mean, if I press them on the ground, so they deform to some kind of egg-ish form, and take my hand off rapidly it will jump off the ground.
the same will happen if I put another superball (always have to think of this big kid with his acoustic... [img]/images/graemlins/laugh.gif[/img] ) right under it and press them together.
the material will get back to it's usual form, the ball. there is an acceleration in this progress and since mass is slowly in reaction with that, the ball will even have speed when it's usual form is already there again.

it's not that easy for me to discuss things like this in english, but I'm sure the speed should not change all that much. energie is constant, the deforming will cause some warmth inside the material, but where else should it go?
as long as the ball get's the ball-form again after bouncing, all the energy provided by the material under pressure is gonna be revealed again.

not sure if this makes sence to anyone... [img]/images/graemlins/laugh.gif[/img]

actually I think the loss in energy should be compareable to the loss in hight if you bounce it on the ground in right angle.


but how do you define 100% elastic anyway?

Re: I have a question.. can\'t get it out of my min

For the balls to just drop to the floor (hehe, I just said balls drop to the floor [img]/images/graemlins/laugh.gif[/img] ), they would have to be EXACTLY identical in mass, material (this is where the elasticity comes into play) and velocity and be traveling EXACTLY parallel to each other along the same plane (i.e., straight at each other). Otherwise the different velocity vectors come into play.

While you guys are playin' with yur balls...I'm gonna go find something important to watch on tv.

It's a matter of how much of their energy is absorbed in the collision. A lot of energy is lost when the 2 balls are momentarily squashed together (Like a bugs ass going through its mind right before it hits a windshield) and energy is lost when the ball bounces in the other direction. The balls will definitely bounce off each other, but they will not go in the opposite direction at the same speed they connected at.

Well, no of course not, but they will rebound.
