Re: Standard Gravity



The actual gravitational acceleration depends on your position - it's
different at different altitudes, different at the poles than the
equator, etc.

However, people frequently talk about the acceleration of objects in
terms of "g," like "the airplane accelerates with 4g," which gives you
a good idea how hard you will be pressed into the seat. To make sense
of these "g"s, also called "galileos" or "gees," you need one value for
it.

So an acceleration of "4g" is (exactly) 39.2266 m/s^-2.

I wouldn't use or mention this in lecture, though.

Does anyone what this link refers to when giving an exact value of
standard gravity? I'm not quite sure what this really means?

Any ideas welcome. Thanks,
