Imagine That You Could Ride A Baseball That Is Hit Hard Enough For A Home Run. If The Baseball Is Your Frame Of Reference, What Does The Earth Appear To Do?
Introduction
Imagine yourself standing on a baseball field, watching a batter hit a home run. The ball soars through the air, and you're suddenly on it, riding the thrill of a home run.
