Why does a rubber ball called "Crazy Ball " used by children bounce much more ?
608626
Due to law of conservation of energy. The kinetic energy it gains during falling is restored in the rubber at the time of collision while in other balls it is lost in sound & heat. So the crazy ball bounce much more than other balls.

I have an idea, wrap your kid in bubble wrap and never ever let him do anything fun! That way he'll be safe AND miserable! Yes, get him a trampoline, but teach him how to be responsible with it and enforce that responsibility, i.e. only so many people on at a time, no wrestling matches, and by all means flip! That's what they're for, and he's not going to want one when he's fifteen. I had access to three trampolines because of family by the time I was six and I've never broken a thing, but if I had, it would have taught me not to be retarded on the trampoline. Kids aren't glass.

Why is it these days that people seem to think that kids are hyper-active? It is NORMAL for children to be energetic. You worry when they are NOT energetic. This is when they are learning the most and need to have things to do that will help them learn. Sometimes, you need to get them out and let them just run and jump and climb, so they can develop their muscles, as well as wearing them out enough so they will pay attention when you are trying to teach them things that require them to sit still.\nLittle boys are usually far more interested in the physical exercise than the other things, and this is also normal. Don't try to push them into doing things they are not ready to do. Don't let other people tell you that there is something wrong with your child, because he is different from others. We are ALL different. DON'T let the doctors give him drugs to "calm him down."

The ball (like basketball) is spherical (circle) because it is easier to let it bounce to where you want it to bounce than when it is any other shape. In other words, a spherical ball is easier to control...

My guess is 2 things... First of all, the lower the air pressure, the less resistance that the ball will encounter along its path.  Secondly, if the ball is hollow (e.g. a tennis ball or basket ball) then the pressure difference between the inside and outside of the ball will reflect how easily it will bounce.

The more pressure, the harder the ball is. If it doesn't have enough pressure, kicking it won't be very effective. But if it's plump, the ball will fly much easier.

The thin light bat allows you to better control when hitting pop-ups/grounders to individual players.  This exercise was called fun go at some point and thus the bat became fungo.  Why fungo?  Probably some kids were having fun making the ball go where they want and fungo was born.

You are soooo right.\nHow can they call a game 'foot' ball, when it is theoretically possible to go through an entire game without feet making contact with the ball, its absurd.\nThen again, only in America.\nSeems like alot of these answerers are 'foot'ball loving yanks.

The more pressure a ball has inside it, the less its surface dents during a bounce and the more of its original energy it stores in the compressed air. Air stores and returns energy relatively efficiently during a rapid bounce, so the pressurized ball bounces high. But an underinflated ball dents deeply and its skin flexes inefficiently. Much of the ball's original energy is wasted in heating the bending skin and it doesn't bounce very high. In general, the higher the internal pressure in the ball, the better it will bounce. However, the ball doesn't bounce all by itself when you drop it on a flexible surface. In that case, the surface also dents and is responsible for part of the ball's rebound. If that surface handles energy inefficiently, it may weaken the ball's bounce. For example, if you drop the ball on carpeting, the carpeting will do much of the denting, will receive much of the ball's original energy, and will waste its share as heat. The ball won't rebound well.

Rubber.  Players used to use rubber balls, but they bounced and rolled too much.  With experimentation, they found that slicing the top and bottom off created a puck that slid across the ice and was easier to control.

a basketball will bounce the highest of these objects because it is mad of a harder material whose material will retain its shape more readily than the others. also it has higher air pressure inside.

Since "gatorball" is another name for "speedball"...\n\nhttp://en.wikipedia.org/wiki/Speedball_%28American%29

I know, i have no idea why they do that!!! maybe the little kids are like lucky charms or something

Rubber, like many other materials has a property called ELASTICITY, that is the ability of an object to recover its shape after a deformation.\n\nSo, when the ball bounces, the force of the hit deforms the ball, and it recovers its shape because of elasticity, "pushing" ground in the opposite way, as Newton´s Second Law states.

When you hold a ball up in the air, it develops potential energy because gravity wants to pull it down.  As the ball is dropping, that potential energy became kinetic energy, but loses some energy because of friction with the air.  At impact more energy is lost to the ground via thermodynamics (heat loss) and deflection (strain energy transfer).  The ball bounces back up with the remaining energy.  Something like that, better to ask a physics professor in high school or college :)

I've always though the standard was a waist high bat and have the kid hold the bat straight out. If he can't hold it straight it is too heavy.

Our coach used to set up 55 gallong rubbermaid trash cans and we'd have to hit them with enough force to knock them over.  Since they are smaller than a goal from 30-40 feet away it makes a pretty good challenge just to consistantly hit it.  \n\nOf Course when I last played soccer I was only 14.
