Rubbing wool on the ball transfers electrons (negatively charged) from the wool to the ball. The excess charge builds up and produces static electricity.

Why cant you throw a rubber ball far like a hard ball?
If the ball is lighter than the hard ball, then it is because a heavier ball has more force when moving at the same speed as a lighter ball. If they weigh the same, then it is because in some instances, with certain materials, a hard ball with a lot of "ping" to it will bounce further than a rubber ball, due to motive energy being converted to heat in the polymers of the rubber ball, thus decreasing the total motive energy.
What makes a marble bounce?
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.wmvSkrommel
What factors affected the bounce height of the ball?
Well there are quite a lot of variables-factors- that can effect the height of a dropped ball..........such as...........the weight of the object, or ball droppedthe height in which the ball was dropped fromthe materials that make up the ball( for instance, if it were a bouncy rubber ball, then it would effect the ball's rebound)the surface that the ball hit(like if it were a slanted surface the ball would launch diagonally and wouldn't go as high)and also the force in which the ball was thrown or dropped could possibly affect the ball's rebound.
Why does a turkey wishbone turn rubber when placed in vinegar?
A turkey wishbone will turn to rubber when placed in vinegar because the vinegar dissolves the calcium. Calcium is what makes a bone hard.
A rubber band slingshot shoots a 25g stone What is the initial speed of a stone if the rubber band is drawn back 0.15m with a force of 27N?
This is hard to measure because you need to know the rebound of the rubber band and the force pushing against it, e.g. if you were under water the force will be different.
When two nonconducting materials such as hard rubber and fur are rubbed together what kind of electricity is generated?
Static

Is rubber hard or soft?
It can be either. Consider a hockey puck. And consider a Nerf ball. Both are rubber.
What is the ball in a Compaq mouse made of?
The balls are made of hard rubber.
What bounces better hard or soft rubber band ball?
you want a soft rubber band ball with strechy rubber bands,but you also want to be carefull that you dont make it to big and to small
What happens if the baseball ball is frozen?
It becomes hard.
What is in a lacross ball?
a lacrosse ball is a ball made out of solid rubber. therefor it is very hard. you are very smart for asking this question jack lenox
Why does a rubber ball bounce on a hard surface?
The energy exerted when the runner ball hits the hard surface is compacted and then repelled in the opposite direction. It's basic kinetics. :)
What is a lacrosse ball made of'?
Lacrosse balls are made out of solid indian rubber.
What is are bouncy balls made of?
If you are talking about a rubber band ball, you scrunch up a rubber band and then you wrap another rubber band around that. Keep going (if you can) around it until it's the size of a golf ball. When it reaches that size, it will be roughly round. Hope I helped! ps. if you were talking about a manufactured rubber ball then sorry, i dont know.
What is Ebonite?
Hard rubber. It's named after the bowling ball company that invented it.
Why do balls bounce high on tiles?
Well it is hard to explain but i will give it a try. It actually depends on what type of ball your talking about. Baseball, Basketball, Waffle balls, etc you looking at a bouncy ball its actually because of the rubber used when you bounce the ball hard do you here that slamming sound? That is the sound of the tiles and the ball meeting and since the tiles are a hard smooth surface rubber works well on it so that's how i think of it.
