Ball Science?

FLOORBALL U SAY ///


A Canadian Hockey Blog just recently discovered Floorball and said, “It looks slow” - without probably even trying it....
It is however true, as You compare the players, a player on skates is without no doubt faster as a player running. But as we all know the Floorball ball flies substantially faster as compared to a Hockey Puck. So what does this mean in reality?



I say that the comparable speed difference in player versus the ball/puck is higher in Floorball as compared to Hockey. The comparable speed difference it not something You not too often hear about and I am not 100% certain that this is a crucial matter or maybe it is only me thinking in these terms? However it sounds very interesting to me.The comparable speed difference - most likely means that it is beneficial to play the ball, and to play the ball faster in Floorball, something I suspect create “a driving force” for a team-game that is more focused on passing as compared to running the ball? So Floorball is probably more of a “team sport” and it is more important to “own” the ball within the team using many players? This is also related to the size of the field and number of players per square area and some other dynamics too. A conclusion might be, Yes I suspect; Floorball to be faster than Hockey. And as I see a Hockey Puck airborne it looks somewhat like slow.

Now lets talk Golf.
Scientist say that as you hit a golf ball and ignore any recoil in the club, spin, elasticity etcetera and other things related to the real world. If You only look at the basic physics involved. They claim that the possible and theoretical speed of that ball is the speed of the club PLUS the speed difference between the ball and the approaching club. Sounds weird? To me it does, but in the theoretical world this would mean that the possible ball speed is twice as high as the club speed at such perfect conditions. I am not certain if I believe this myself but a very serious Swedish Tech paper just described it like this..

A short comparison on the golf ball and the Floorball ball indicates that the bounce in a golf ball is much higher as compared to a Floorball ball. As You drop a Floorball it might only bounce 25-35% up from the Floor. A Golf ball bounce much higher if the floor is hard and stiff.
Both balls bounce higher as a Puck though even if it comes down right on one edge. So maybe it is not just the “ventilated blades” in Floorball that gives the ball its full speed, even if the Floorball ball almost is designed as a little air break?

Did You know that there is a Golf ball invented some 40 years ago that it is prohibited to play with?
It flies too fast, too long and too straight. I think about the Polara ball design. It has two different kind of dimples, with the groves lined up on the surface so the ball flies with a spin that keeps the ball very stable, with less curvature and flies both faster and longer than any other golf ball. In principle this ball has an equator of different dimples and another kind at the "poles" that makes the airflow produce a spin that makes this happen. The Golf regulators has prohibited this ball.
If we do not care about the dimples and just look at the holes in a Floorball they tend kind of to be slightly more frequent towards the “equator” too on the ball as compared to the poles. However I can not do any further investigations on this even if I would love to. But the placements of the holes in a Floorball ball makes me think of the Polara Golf ball.

Did You know that some very prominent Golf courses just during recent years have been prolonged in some sections to meet the demand of balls flying longer and longer as clubs sent them further and further? Technical advancements in clubs and balls as well as maybe in players too, drove this re-design of the golf holes.

I do know that a former IFF president does not fully promote the current development in Floorball with balls flying faster and faster. One day maybe the IFF must step in and regulate the balls harder as is done in Golf?

What is Your take on this?

Caution

Research suggest that eye-injuries are more common in Floorball as compared to Tennis, but less common as compared to Squash (similar to Racquetball).
To minimize this risk of injury Floorballcentral recommend: Use certified protective eye-wear (mandated in many European areas for the youth). Do not lay down on the court. Follow the rules strict on stick height.

Also if you get addicted to this sport - do not blame us!
