The physics of basketballs
When UT Arlington Department of Physics chair Jim Horwitz was asked to do a study of the new NBA basketball, you might say he jumped at the chance.

Dr. Horwitz was approached by representatives of the Dallas Mavericks to compare the new synthetic basketball to the leather ball used for many years by the National Basketball Association.

He, along with physics Professor Kaushik De, began doing comparative tests Oct. 14 on the two balls. Dozens of students participated in the tests, which took place in the Chemistry and Physics Building, Science Hall and the Activities Building.

They sent a report to Dallas Mavericks’ owner Mark Cuban on Oct. 27. Among their findings: The synthetic ball does not bounce as high, does not bounce straight every time and becomes slippery when wet.

“During our bounce tests, we observed that the synthetic ball bounced more erratically compared to the leather ball,” Dr. De said.

The new ball, which has been unpopular with many NBA players, bounced an average of four inches lower than the leather ball when dropped to the floor, and any amount of perspiration made the synthetic ball harder to grip.

Horwitz and De have received national and local attention for their investigation. ESPN, The Wall Street Journal, the Associated Press, The Dallas Morning News and Star-Telegram are among the media outlets that have trumpeted the research.

“I’m not sure exactly why they chose us to perform the tests, but we have enjoyed doing it,” Horwitz said. “And we still have more tests to perform.”

They plan to do testing in the wind tunnel of UT Arlington’s mechanical and aerospace engineering laboratory and, if possible, at American Airlines Center.

“A big thank you to UTA and all the hard work they did. They are a first-class program and did a wonderfully thorough job,” said Cuban, who concludes that the NBA should keep the new ball.

Although the NBA is using the synthetic ball, UT Arlington and other schools in the NCAA will continue to use a leather ball.

Haha. How long is Cuban going to keep this act up? :cool:

Man I missed this one.

Good article. Funny Cuban.

You can get all the professors in the world to say the ball isnt as good, it doesn't matter to Emperor of Basketball Stern.

its sad when the NCAA is smarter than the NBA.

Sad but it's been that way for a while imo.
