My PSO told me that a Brunswick rep was doing a demo at his shop.
He has a golf ball sized sphere of DynamiCore and a sphere of the normal filler used in most bowling balls.
He dropped the normal filler sphere on the hard floor from a height of about 4 1/2 feet.
When it hit the ground it bounced up and down a few times and then came to rest.
Then he dropped the DynamiCore sphere from the same height.
It hit the ground and never moved a millimeter!
It was like it stuck to the ground like a piece of iron on a super magnet!
The point is, the DynamiCore sphere depleted all of its energy of motion into the floor and had nothing left to rebound with.
This material is like Captain America's shield.
It is not so much that it increases the COR to some illegal level, it is that it releases all of its energy of motion into whatever it hits.
That is why it increases the carry ability of a bowling ball.
ummm, I think you have a few misnomers in these statements. First COR would be 0 here for the dynamicore, since it had no velocity after the collision. That would constitute a perfectly inelastic collision.
The kinetic energy of the moving ball is lost to either deformation or in sticking to the other object, in this case the floor. I would believe this would be terrible for bowling. I would want a maximum COR so that all the energy of the ball is transferred to the pins and no energy is lost to deformation. It would be like using your driver in golf on a playdough ball and just having it stick to the club face.
Please correct me if i'm wrong here as I would still think if the filler absorbs all the energy of the collision, then you would get no effective pin motion when the ball hit them.
Are you sure you didn't get the two balls mixed up?
