I wonder if it might have been better to label the position variable "dy" instead of "dt" as the first derivative is usually written "dy/dx."

Also, I believe that he says that position is determined by movement along the x-axis. I was led to believe that the position of an object is indicated via the "y" axis and that the "x" axis is usually reserved to show time. In other words, delta y (the change in position) OVER delta x (the change in time). Someone please correct me if I'm wrong!

@spacechick88 Variables (axes) can be whatever you want. I felt that "t" for time made perfect sense, and is indeed the usual standard. The y-axis, since it's often drawn vertically, is often used for vertical height. But the bottom line is, you can use whatever letters you want.

@ 05:27 - shouldn't it be dt X t = dt2?

Cause dt X dt = d2t2

[Stedwick]

@PauLL95 No, because dt is a single unit, not two separate units. It's like apple x apple = apple^2, not a^2p^2p^2l^2e^2.

"accelera-SHON" hahah

at 03:04 shouldn't it be m/(s*s) and not m/s/s ? since the seconds are multiplied in order to become squared..?

@Stedwick what if it was dt x t? would it be t^2d

I actually found that harder to understand than via calculus.
