Fluid resistance is the limiting factor in objects falling in a fluid. A rain drop has a terminal velocity for the same reason that a boat has a top speed: drag is equal to force pushing it at that point. If you want to go faster, you need to increase the power. (or reduce drag, which is why fast boats plane). |
