题型:实验题

某实验小组采用如图所示的装置探究功与速度变化的关系,小车在橡皮筋的作用下弹出后,沿木板滑行.打点计时器工作频率为50Hz.

(1)实验中木板略微倾斜,这样做__________________;

A.是为了使释放小车后,小车能匀加速下滑

B.是为了增大小车下滑的加速度

C.可使得橡皮筋做的功等于合力对小车做的功

D.可使得橡皮筋松弛后小车做匀速运动

(2)实验中先后用同样的橡皮筋1条、2条、3条……,并起来挂在小车的前端进行多次实验,每次都要把小车拉到同一位置再释放小车.把第1次只挂1条橡皮筋时橡皮筋对小车做的功记为W,第二次挂2条橡皮筋时橡皮筋对小车做的功为2W,……;橡皮筋对小车做功后而使小车获得的速度可由打点计时器打出的纸测出.根据第四次的纸带(如下图所示)求得小车获得的速度为__________________m/s.

若根据多次测量数据画出的W—v草图如上图所示,根据图线形状,可知对W与v的关系作出的猜想肯定不正确的是_______________。

A.W∝      B.W∝       C.W∝       D.W∝

(4)如果W∝的猜想是正确的,则画出的W一图象应是__________________;

(5)在本实验中你认为影响实验效果的可能原因是_______________________

______________________________________    (只要回答出一种原因即可)
