• Normal Reaction

  普通作用力

•  Centripetal Force

  向心力

•  Gravitational Force

•  Kilogram (kg)

  公斤

•  Degree Celsius (°C)

  攝氏度

•  Tesla (T)

•  Robert Hooke

  羅伯特。虎克

•  James Hooke

  詹姆斯。虎克

•  Isaac Hooke

  艾薩克。虎克

8. Why is nuclear fusion NOT a means of producing energy yet?

核裂變尚未被應用於產生能源，原因為：

•   It can only take place in high temperatures

  核裂變只可於高溫下進行

• The energy input to achieve nuclear fusion is most of the times greater than the energy output

  大部分時候，核裂變所需能源較所產生能源少

• Great amounts of nuclear waste are produced

  核裂變會排放大量核廢料

• It is only observed in suns, and there are currently no facilities to perform nuclear fusion

  核裂變目前僅可觀測於太陽，暫時沒有設施進行核裂變

9. Which of the following systems are not chaotic?

以下哪項系統並非混亂？

•  A pendulum attached to the bottom of another one

  鐘擺下連接另一鐘擺

•  Three massive bodies attracting each other

  三個巨型物體相互牽引

• A light ball rolling between two hills with friction

  輕球體於具摩擦力的兩座山間滑行

•  Air particles colliding with each other

  空氣粒子互相碰撞

10.  Which of the following is NOT a law of thermodynamics?

以下哪項不屬於熱力學定律？

• If two systems are both in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.

  如果兩個系統分別與另一系統達成熱平衡，兩個系統間必然形成熱平衡。

• Energy can be created or transformed from one form to another, but can not be destroyed.

  能量可被產生，或轉換形式，但不可以被消滅。

• Not all heat energy can be converted into work in a cyclic process

  在循環程序中，不是所有熱能皆可轉換為功。

• The entropy of a system approaches a constant value when its temperature approaches absolute zero.

  當系統的溫度趨向絕對零度，其熵將趨向不變數值。
