I didn't know that.

Cool.


Why is a drop of water exempt from the laws of gravity?

They hurt when you run into them at 120mph.

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.

It's not, of course. 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).

I think it's because of the shape a raindrop takes as it falls in air.
Forms a natural parachute so it's terminal velocity is limited by the shape
of the droplet.

They hurt when you run into them at 120mph.


You can run 120 m.p.h.???

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

Mine might go 120, but I'm not brave enough to find out.

Some people have a need for speed, others don't.
