 Today in physic class, my teacher had done the realm of the final exam, so he decided to teach the additional concept of solving the energy related question, which is internal kinetic energy. This new concept of energy emphasizes the two objects have relatively velocity, causing a relatively kinetic energy between the two objects. for instance there were two objects started with a relatively movement and subsequently they relatively still, their must have done some work to cause this resault, then we can erect an equation about W= delta Ki[internal kinetic energy]+Kc[central kinetic energy], through out this equation we can obtain the value of velocity .

Today in physics class, my teacher had already covered all the material for the final exam, so he decided to teach an additional concept related to energy: internal kinetic energy.
This new concept emphasizes that when two objects have relative velocity, there is kinetic energy associated with their motion relative to each other.
For example, if two objects initially move relative to each other and then become relatively stationary, some work must have been done to bring about this result.
We can then set up an equation:
W = ΔKᵢ (internal kinetic energy) + K𝚌 (center-of-mass kinetic energy).
Using this equation, we can calculate the velocity values involved.

今天在物理課上，老師已經講完期末考範圍的內容了，所以他決定額外教一個與能量相關的新概念：內部動能（internal kinetic energy）。
這個新概念強調，當兩個物體之間存在相對速度時，它們之間就有一種相對的動能。
舉例來說，如果兩個物體一開始有相對運動，後來變得相對靜止，這過程中一定有外力做工導致了這個結果。
因此我們可以建立一個方程式：
W = ΔKᵢ（內部動能的變化）+ K𝚌（質心動能）。
透過這個公式，我們可以求出相關的速度值。
