Well the moon's gravitational pull is about 6 times less than on Earth. NASA designed a telescoping horizontal support that would hinge to the top
of the pole. The flag itself was a commercially available nylon flag. A hem was sewn into the top edge into which the horizontal crossbar could be
slid. The astronaut deployed the flag by driving the steel-tipped aluminum pole into the surface, then raising the crossbar on its hinge until it
locked into the horizontal position. He could then extend the telescoping segment of the crossbar to support the entire width of the flag.
The flag was held oustretched by the crossbar through the top hem. The inner bottom corner was fastened to the pole. The outer bottom corner is free
to move which causes the same effect as a pendulum. The top crossbar would bend and when the flag pole was released the bar would snap back causing
the bottom part of the flag to sway back and forth. No wires were in the flag. The reason it looks like it is waving is because the pendulum kept
swinging back and forth and there is no atmosphere on the moon to stop it. You cant do this on Earth because air would exert pressure on the flag
slowing it like a parachute slows a skydiver. The flag could have been smoothed perfectly flat. Again, it would have stayed that way because of the
top bar not alowing the flag to fall against the pole.
When they tried to walk NASA originally proposed a "kangaroo hop" whereby the astronauts would hop with both feet and then land with both feet.
Aldrin found this to be very awkward and unnatural. The "lope" (as Armstrong named it) turned out to be a good compromise. This is the
characteristic Apollo stride whereby the astronaut puts one foot in front of the other, pushing off with one foot and landing on the other foot, but
not separating the feet as in a normal walking stride.
Many people confuse weight with mass. The former is affected by gravity and the latter is not. But things like momentum and inertia are a function of
mass. Consider a 175-pound (80-kg)astronaut wearing 120 pounds (55 kg)of equipment for a total of some 300 pounds (136 kg) on earth. On the moon he
would weigh only one-sixth that amount, 50 pounds (23 kg). But he would still have 300 pounds (136 kg) of mass.
In order to get moving you have to overcome inertia, and you have the same intertia on the moon as you do on earth. And in order to stop you have to
overcome momentum, which also is the same on earth as on the moon.
On the moon your ability to stop and start is impaired by your relatively light weight. Your grip on the lunar surface would be a matter of friction,
and friction depends on how hard you're being pulled down against the surface. Low gravity means a weak force pulling you against the surface, and
that means less friction, and that means less grip. So if you tried to run you'd just slip and slide. And if you tried to stop you'd skid.
