In the gravity free conditions of the moon, can you step on your left foot and go to the sky with yo

Stepping on the left foot and the right foot to the sky and pulling your hair to fly, are all plots in some martial arts ** that ignore physics, they are all made up, the moon also has gravity, you can't fly in this way, even if there is no gravity.

The right foot steps on the left foot, both are forced, but they are the same size and opposite direction, and the action time is also the same, according to the law of conservation of momentum, the momentum obtained by the two instantaneously is also equal in size and opposite to the direction, the two are canceled, can not play the role of accelerating the object, the left foot and the right foot are long on their own body, no matter how tossed, the movement state of the whole human body will not change much. In the state of gravity, stepping on the ground and jumping up is different, the earth has nothing to do with itself, when people jump, people are also subjected to greater force, and the instantaneous momentum can make the human body move upwards for a certain distance.

The moon is also a rocky celestial body, there is also a large gravitational force, but it is much smaller than the earth, during the Apollo moon landing, did an experiment to verify Newton's laws, the astronaut held a hammer in one hand, a feather in the other, and let go at the same time, the last piece landed, the law of motion conforms to Newton's laws, that is, Newton's laws are also applicable on the moon, and the laws of motion related to classical mechanics are also applicable, and the left foot can not step on the right foot on the moon. The sight of astronauts living on the space station also shows that such an idea does not work, and astronauts still have to step on the side wall of the spacecraft to move, even when they are out of the capsule.

It may be better to take off your shoes and throw an object with a little mass in the opposite direction, because they are two objects, and the impulse of motion can make people move backwards a little bit, and momentum and mass are related. In fact, stepping on each other's left and right feet to the sky, just like Wudang's Tiyun Zong, violates the basic principle of conservation of momentum. The upward movement of the human body necessarily requires the downward movement of another object in order to maintain the conservation of the momentum of the system.

Just like a jet rocket, the thrust pushes the main body of the rocket upward, but the ejected material fuel is downward.

This is not possible, the forces are phased, and the Moon is not gravityless, the gravitational pull of the Moon is 1 6 of the Earth. Even if astronauts drift away from spacecraft in outer space, they will not stop flying forever.

I don't think so, because there is no gravity, and people themselves are not under their control at all, and it is impossible to make such an action.

No. Because in the gravity-free conditions of the moon, stepping on the left foot and the right foot will cancel each other out of force, so you can't step on the left foot and go to the sky with the right foot.
