Hello,

We all know about the atomic clock on an airplane experiment, where it
was experimentally shown that time relative to the Earth will be
faster on an airplane.

It is my understanding that time will also go faster relative to the
Earth if a person is in a less powerful gravitational field. Is this
correct?

If this is correct, then how much of the "time-shift" of the atomic
clock in the airplane is caused by its increased speed, and how much
of it is because it is in a lesser gravitational field (feeling less
force?)

Thanks.
