Can people tug-of-war in space? What is the feeling of tug-of-war in weightlessness?

In space, due to weightlessness, the experience of many things is completely different from that on earth, such as tug-of-war. Can you imagine what it's like to tug of war in space?

Foreign media showed an extraordinary tug-of-war experience in space through a video. It is understood that this video was shot in 2009. JAXA astronaut Koichi Wakata and Canadian astronaut Robert Sesk demonstrated the tug-of-war in space on the International Space Station.

Koichi Wakata and Thursk used a white towel as a tug-of-war rope. As a result, as long as they worked hard, they bumped into each other, which was "greeting" and "hurting" each other, which was completely different from the game experience on earth.

In fact, the principle is very simple, that is, Newton's third law of motion: the force and reaction between two interacting objects are always equal in magnitude and opposite in direction, and act on the same straight line.

In other words, when you exert a force on an object, it will exert the same force on you in turn. On earth, this law is not obvious in outer space because of gravity.

Back to the two tug-of-war astronauts, when they pulled the towel backwards, they transferred the force to the towel, and the towel exerted the same force on them. Two people were pulled forward by towels, and the final result was that they collided.

Knock on the blackboard: review Newton's third law;

Newton's third law of motion studies the interaction mechanism between objects. The object of study is at least two objects, and the interaction between two or more objects can always be divided into several pairs of interacting objects.

Action and reaction are mutual, interdependent and interdependent, and both of them take each other's existence as their premise. Without reaction, action does not exist; Force has materiality, and it cannot exist without objects (matter); Force is always produced by the interaction between two or more objects.

Newton's third law is also instantaneous, that is, acting force and reaction force are generated, disappeared and changed at the same time. Action and reaction are equal, so it doesn't matter who they are.
