I believe Kayvon said it's equivalent to q, just a convention for the positions you're trying to solve for

It seems Kayvon has been using u(t) as convention for an exponential function. See slide 8.

so a is just velocity?

What is the meaning of the first formula in this slide? Also, it seems to me that the time step has something to do with the velocity.

I think you can simply think of the first equation as a definition of a linear system. We have the exact solution for this linear system and we want to see if Forward Euler will output reasonable solution.
