Why is a drop of water exempt from the laws of gravity? 32 feet per second per second acceleration in a vacuum; most rain drops don't fall in a vacuum. And yes, a pound of lead will hit the ground faster than a pound of Styrofoam here in the real world. http://electron9.phys.utk.edu/phys13...2/Freefall.htm |

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). |

Forms a natural parachute so it's terminal velocity is limited by the shape of the droplet. Eisboch |

Several motorcycles will run at 120 mph. Therefore the rider is running 120 mph. |
