實驗目的：
1、觀察過山車的工作過程。
2、認識離心現(xiàn)象。
3、探究能量之間的轉(zhuǎn)化過程。
實驗器材：
過山車、鋼球。
實驗過程：
1、將儀器放在桌面上，并將小球放在高端的槽內(nèi)。
2、用一個手指托住鋼球的底部，并將鋼球頂出槽內(nèi)，注意觀察。
探究問題：
1、鋼球從高端下落后，速度為什么越來越快？在繞著軌道運動時，為什么不會掉下來？
2、如果鋼球從低端開始釋放，鋼球會掉下來嗎？
3、如果鋼球釋放點的高度與圓形軌道的點在同一水平線時，鋼球會掉下來嗎？
4、當鋼球剛好落入低端的槽內(nèi)時，大約損失了多少能量？
實驗結(jié)論與體會：
（以下由學生總結(jié)并交流，也可由教師引導得出。）
注意事項：
實驗完畢，應將小球放回高端。
13.The model roller coaster
Experimental purpose:
1.Observe the course of moving for the roller coaster
2.Knowing the centrifugal phenomena
3.Researching the transition between the different types of the energy
Experimental equipment:
The model roller coaster, steel ball
Experimental process:
1.Put the instrument on the table, and put the ball in the top trough.
2.Support on the bottom of the steel ball with a finger, and let the ball leave the trough. Watch carefully.
Researching issues:
1.Why the speed is faster and faster when the ball falls from the top? Why the ball does not fall down when move around the orbit?
2.Whether does the ball fall down when let go the ball from the low place?
3.Whether does the ball fall down when they are the same for the height of the releasing point and the highest point of the circular orbit?
4.How many calories are lost for the energy when the ball drop into the low trough？
Experimental conclusions and the experience:
The followings can be concluded and discussed by the students, or guided to get by the teachers
Caution:
Put the ball back on the top trough after the experiment.
