When you think of acceleration, you probably think of, well, acceleration. It seems like an open-and-closed case, a subject you can learn and move on from, one of those things you don't bother paying attention to. This assumption is completely wrong. Whether you know it or not, acceleration is the only reason you're alive today. Okay, so maybe that's a bit drastic, but acceleration is something you need to know in order to pass Physics class. There are two kinds of acceleration: Acceleration due to gravity, and free-fall. In order to cover both of these topics, I wrote about an alien falling from outer space - free-fall - onto Earth - acceleration due to gravity. Jeremy, the alien, will explain this topic further during his adventure.
