把發車音樂配上歌詞

不少在日本的鐵道迷也會把發車音樂配上歌詞，我現在也開始嘗試，但配上的歌詞是來自IGCSE（9-1）物理科的課本。
以下是我的一些作品：
1. （原曲：東武鐵道-Passenger）
Work is defined as energy transferred to objects by a force which is when a force exerts on objects over a displacement
Parallel to the force and it has the following ratio that work done equals to force times the object's displacement
2. （原曲：夕焼け小焼け）（八王子1-6台）
As work done can convert to kinetic energy, so it is half of mass times velocity square
3. （原曲：たき火）（豐田1-4台）
When a force moves mass upwards in constant velocity, then there is no kinetic energy gained from it
Then potential energy is work done by the force, which equals force times displacement called as mgh
4. （原曲：熊谷市歌B）（籠原1-2台）
Power's the rate when work's done or energy transferred, it can be found by work done or energy over time
5. （原曲：上を向いて歩こう）（友部1台）
Mechanical energy's sum of kinetic energy and potential energy combined together,
When no external work is done, mechanical energy's conserved
6.  （原曲：スプリングボックス）（池袋7-8台）
Efficiency is useful energy output over total input times hundred percent
7. （原曲：JR東日本特急車內提示音1）
Pressure is defined as normal force exerted on a surface per unit area
