从高处释放一个物体,在重力作用下,物体竖直向下自由运动,这种运动我们把它叫做自由落体运动.当然,真正的自由运动落体运动只有在没有空气的空间里才能发生.在日常生活中,由于空气阻力较小,我们也可以把日常物体的自由下落运动视为自由落体运动.

运动时间t(s)12345
时间的平方(s21491625
运动速度v(m/s)1020304050
运动距离s(m)5204580125
小明同学为了研究物体下落过程中运动速度与运动时间的关系,用一个小球做了一组实验,得到的数据如右表所示:

根据上述数据,归纳出运动距离与时间之间的数学关系:

     Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always

tired and was losing weight fast. Diagnosed with diabetes (糖尿病), Thomas would need to inject himself with insulin (胰岛素) three times a day for the rest of his life or risk nerve damage, blindness, and even

death. And if that weren't bad enough, he had no health insurance.

     After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton,

Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar , and created

diabeticrockstar.com, a free online community for diabetics and their loved ones-a place where over

1,100 people share personal stories, information, and resources.

     Jason Swencki's son, Kody, was diagnosed with type diabetes at six. Father and son visit the online

children's forums (论坛) together most evenings. "Kody gets so excited, writing to kids from all over,"

says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone."

Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with

24 million diagnosed cases. And more people are being diagnosed at younger ages.

      These days, Thomas's main focus is his charity, Fight It, which provides medicines and supplies to

people-225 to date-who can't afford a diabetic's huge expenses. Fight-it.org has raised about

$23,000-in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in

the Caribbean. 

  Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still

doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into

finding a cure," says Bentley Gubar,  one of Rockstar's original members. "But Christopher is the only

person I know saying people need help now."
