Clocks

SouthernCharm asked:


I have a kitchen wall clock and when I hang it,
the gravity pulls down the second hand
around the #4 mark so its not keeping
time and runs too fast.
When I lay the clock down flat, it works fine.
Anyone know how to fix this second hand?
Its a battery operated clock.
Thanks.
I tried most of your suggestions
(except the super glue…lol)
and nothing is working yet.
It has something to do with the balance of the second hand being off I think.

Wikipedia says that “Gravitational time dilation (GTD) is a consequence of Albert Einstein’s theories of relativity [...] a clock at a different gravitational potential is found to tick at a different rate than one’s own clock.”

“clocks which are far from massive bodies (or at higher gravitational potentials) run faster, and clocks close to massive bodies (or at lower gravitational potentials) run slower.”

Is this due to the fact that the higher clock is simply further away from the earth than my clock, or because it experiences less pull from gravity?

If two objects were released from different heights (so were both in free fall), would they have the same GTD because they are not experiencing any effect of the gravity, or would they have different GTD because they are at different heights (i.e. gravitational potentials) from the earth?

What about objects in orbit? They are constantly accelerating (i.e. their vector of movement is changing) but do they experience GTD?
