OUCH! 186,400 miles/sec Thats funny, I only started going 9 meters per second...per second....persecond...persecond...

PS I don't know of anyone who has actually achieved a measurement for gravity, itself, but we know it induces accelerations in matter and is probably in the lighspeed (+/- a little bit, maybe) range....

But do you like our sense(s) of humor? [6)]

if you must know it is slightly slower than the speed of light.

velocity = acceleration x time
No, actually, acceleration x time is the change in velocity, not the velocity itself.

True enough.
Where do you live by the way? 9.0824 \frac{m}{{sec}^2} is a bit low...

Mr. Robin Parsons is in charge of keeping gravity within tolerance everywhere. Sometimes he plays with the dials to create mischief.

Sorry, it's been a long day. Is 32.174 ft/sec/sec ok? Do you like 9.8066 m/sec/sec better? I live on Shyne Road, first house on the left.
Well, normally g is taken to be 9.81 m/s^2. But you might find it to be 9.08 if you go on a high mountain or something, hence my question. [;)]
