题型:实验题

(8分)一学生利用如图甲所示的实验装置验证机械能守恒定律。该弧形轨道的末端水平,离地面的高度为H。现将一钢球从轨道的不同高度h处由静止释放,钢球的落点距离轨道末端的水平距离为x。

(l)若轨道完全光滑,则x2与h的理论关系应当满足x2=____。(用H、h表示)

(2)该同学经实验得到几组数据如表所示,请在图乙所示的坐标纸上作出x2一h关系图。

对比实验结果与理论计算得到的x2一h关系图线(图乙中已画出),可知自同一高度由静止释放的钢球,其水平抛出的速率____(填“小于”或“大于”)理论值。

(3)实际上轨道是不光滑的,钢球下滑过程需要克服摩擦力做功,已知测得钢球的质量为m,则钢球在下滑过程中克服摩擦力做功大小为

I used to be a very self-centered person, but in the past two years I have really changed. I have started to think about other people        I think about myself. I am happy that I am becoming a       person.
I think my        started when I was at Palomar College. At first, I just wanted to get my       and be left alone. I thought I was smarter than everyone else, so I hardly ever         to anyone in my classes. By the end of my first semester, I was really        . It seemed as if everyone but me had made friends and was having fun. So tried a (n)        . I started asking people around me how they were doing, and if they were having trouble I       to help. That was really a big        for me. By the end of the year, I had several new friends, and two of        are still my best friends today. 
A bigger cause of my new        , however, came when I took a part-time job at a Vista Nursing Home. One old lady there who had Alzheimer’s disease became my         . Every time I came into her room, she was so       because she thought I was her daughter. Her real daughter never        her, so I took her place. She let me       that making others feel good make me feel good, too, when she died, I was       , but I was very grateful to her.
I think I am a much        person today than I used to be, and I hope I will not        these experiences. They have         me to care about other people more than about myself. I        who I am today, and I could not say that a few years ago.
