Δ Huh, that's odd. Wherever I got the triangle from (I forget), it turned into a capital "D"

Ohh, so when velocity changes constantly, the velocity of that total time is just the average of the velocities at time 1 and time 2 then it just so happens that velocity is distance over time and so the total distance over that time is Δx = 1/2(vi + vf)Δt ?

Oh wow, that's really cool. I wonder why it works out that change in momentum is the same as a constant net force multiplied by the change in time?

Why is mv called "momentum" and why is change in momentum called "impulse"? Or is that something I just need to remember..
