【數學+物理】「作功」你絕對沒看過有人高中物理題這樣解！@bprptw

In this video, I teach "power" in a way that's very unlike a physics lesson. I treat force F directly as a function of position x, and then I tell you one thing: The rest is simple— write F clearly, and when you encounter trigonometric functions, just do the integration. You'll see a problem that looks like a physics problem, which I completely transform into a mathematical integration problem, although it takes several times longer to solve than the textbook method, the result is very satisfying. If you like to "hard-solve" problems using mathematics, you'll definitely enjoy watching this video.
