Hello, I am learning how to use calculus to derive the formula for kinetic energy
now, I understandthe majority of the steps in how to do this, however, there is one step where I get totally lost, I will post a picture of the steps and I will circle the part where I get lost. If you see the part circled in BLUE, Why can we just “re-write” those variables? Why can we just switch the positions of the “v” and the “r”?
