Better COR is higher or lower
 

I vaguely understand the concept of COR. But what is a "better" COR, a higher or lower number? In other words, will a ball with .44 COR travel farther or nearer than a ball with .53?

Thanks

COR is an abbreviation for coefficient of restitution. It measures the energy after the collision (in this case the ball and bat) vs. the energy prior to the collision. Energy is lost during the collision to sound waves, heat, ball and bat deformation etc. The bat that transfers this energy to the ball in a more efficient manner will have a higher COR, meaning less energy is wasted.

So to answer your question, higher COR is better - a "hotter", more efficient bat. There will never be a 1.0 or higher bat as that would increase the amount of energy in the system and contradict one of Newton's laws of Physics.

derwil:

It was not Sir Isaac Newton that formulated the equations for the Conservation of Energy. It was Gottfried Wilhelm Leibniz (see Newton vs. Leibniz and the invention of Infinitesimal Calculus; either you are a Newton man or a Leibniz man, :p).

MTD, Jr., and I love this. Thanks.

But wouldn't it be cool if Newton was wrong and we could increase the amount of energy? That would be something!:)

I had advanced Calculus and Differential Equations more than 30 years ago as an Engineering Major.......My oldest daughter graduated as an Engineer about 3 years ago......I was able to communicate with her in her early Engineering Physics classes......and some Chemistry.......but her mathematics and chemistry far exceeded my knowledge.

Damn.....it is tough to get older.

I am thinking about substituting HS science classes.....but am worried they know more than I do.

I do think I could help in English though.....

Like no way lol, you could never keep up with the ROFL's and OMG's ur 2 old to keep up with the young one's version of English!!! Or at least I am....it seems like a new language to me anyway!!

You're welcome! :D

You mean: What if Leibniz had been wrong?

MTD, Sr.

One of your best posts, in a long series of great posts. Hilarious.

Thanks... I thought it was pretty funny, too! :) (But it does need the Geek Zone warning!)
