Because if there's anything that needs a sequel, it's Gravity... right? Okay.
When we left off, we (read: I) devised two ways to calculate acceleration due to gravity in World of Warcraft. The first, more basic approach, assumes constant acceleration and uses the relationship
$$a = {{2h_0}\over{t^2}}$$
The second approach assumes that drag (air resistance) functions realistically in-game, and uses a more complex equation with no neat solution. To reiterate: we will be measuring (directly) the time it takes to fly to an arbitrary height, the time it takes to fall from that height and (indirectly) the total displacement, and then attempting to calculate the acceleration due to gravity and the magnitude of drag.
