Every action has equal & opposite reaction?

Ody Since you jumped in with your two cents this question is for you.
It takes energy as pointed out to get a swing going,and the person on
the seat is its pendulum bob and supplying that energy no outside force
needed. We now go to the Earth's north pole. A pendulum clock is
swinging back and forth in the corner of a large room. I bring in
another pendulum clock that is swinging completely out of rhythm with
the other pendulum clock,and place it in the opposite corner. Here is
the kicker. In a very short time both pendulums are swinging in exact
unison. My question to you Ody is this It took energy to get their
heavy bobs to react in unison (yes?) Show me its counter reaction
I can keep this post going forever. It is a great morning mind exercise
to get the cobwebs(Bud light) out of my head. Go figure Bert

Ody A pendulum shows action and equal reaction so clearly,and yet are
their swing completely 100% equal? Is inertia 100% equal to gravity?
Is accelerating 100% equal to inertia? Is force of impact 100% equal to
weight + speed etc Can time be factored in? Most surely great
distance it is a factor. Go figure Bert

Pendulums show that heavy objects and light objects fall at the same
speed, begause a pendulum with a heavy bob will swing at the same rate
as a pendulum with a ligjht bob. Only the length of the shaft makes a
difference.

Air is not a perfect vacuum .. perfect vacuums are infinitely expensive;
so, given the same surface, a heavier a pendulum ticks longer.

Oddly, we can all look directly at the 1e-21 bar vacuum of the Selene/
moon L1, and it's essentially free for the taking. I mean, how good
of a near perfect vacuum deal is that?

The Earth-Moon L1's “ 10^-21 bar vacuum � isn't “ free for the taking �.

Helium is used to pre-cool liquid hydrogen,
the Saturn V booster ( Apollo ) needed
about 13 million cubic feet of helium to launch.

Helium is very expensive, especially liquid helium.
If getting to L1 allowed us to breed faster, we'd already be there.

It actually is less than dirt cheap and first come first served, and
it looks as though China is going to be in charge of the Selene/moon
L1. I hope we can remain nice to China, because otherwise that nifty
L-1 could offer China quite a tactical (aka star wars) advantage.

I'm not well enough informed about all of that spendy Helium.
However, that's certainly a valid though weird argument about using
the moon's L1, however our DNA might have to evolve into something a
bit rad-hard, or at least as good as that of a cockroach, that is
unless we had a substantial load of nifty shielding as protecting our
Earth-moon L1 abode.

Double-A Length of pendulum staff is the same as planets distance from
the Sun. To prove your point Jupiter and Earth can switch orbits with
no problem. You don't have to drop stuff off the tower of Piza,you can
use an incline plane. Bert

Good point.

Yes. An incline plane can help you access that tower of pizzas. Yum!

But no faster or slower.
