Life is no small thing, and it is full of details. Many of the patterns are actually hidden in objects that we have not yet discovered. Many times we talk about details that no one else has noticed. Then, there will be refreshing perspectives. This time, like last time, you need to use your hands. However, this time the protagonist is not a chess piece but a walnut. When I hold two walnuts in my hand and move them back and forth, why do the two walnuts go one after the other? I was thinking that two walnuts are not subjected to forward and backward forces at the same time, how can there be opposite directions of motion? What do you think about this? Mizukawa is a little poor in words this time, and what he says is a little shriveled.

Mizukawa rice, how do you know for sure that they are both subjected to forward forces? According to the transmission of force, the distance between the two walnuts and the point of force is different. The time for which the two walnuts are stressed is also different.

Duenias, two walnuts are subject to the force. At the point of force, the force becomes two components, and the time taken by the component to reach the corresponding walnut is the same.

Mizukawa rice, the force has not yet touched two walnuts and it has actually become a component force, don't you think this is not reasonable?

Heard of field theory, right? There is a field of force. The hand moves back and forth, creating a dynamic force and force field. The force emits the lines of force, which cover the entire force field. Since both walnuts are in the force field, the line of force is blocked. So, one end of the line of force is back in the hand. In order to alleviate the effect of the bending of the line of force, the force is divided into two forces. The line of force then transfers the two components back to the two walnuts. In order to keep the lines of force of the force field stable, both processes must be at the same time.

Mizukawa rice, the molecules are doing irregular motion and have van der Waals force, so there should also be a force field. According to you, there is also a strong line. If the line of force encounters an obstacle, the force of the object is dispersed. The van der Waals force of the molecule of the object should have been broken down into many components long ago.

The obstacle must be above or below the object of the force. As long as they are in contact, they can cause the force to decompose.

In fact, it is caused by inertia. Regardless of whether it is forward or backward, the walnut should theoretically be immobile. It's like when we're in a car, we're all not moving. And when the car turns, we feel a force pulling us. And this is the force of inertia. Of course, there are multiple inertial forces here. The change from forward to backward is the inertial force 1, and the change from backward to forward is the inertial force 2. And they're the opposite. The two walnuts are each subjected to one of these two inertial forces, so they are one after the other.

Margarita, the speed changes during the exercise! Drivers know that people move at a constant speed on the road, and people don't move. And when the speed changes, the person moves. It is clear that this is the effect of inertial forces. In the forward and backward movement of the walnuts of Mizukawa rice, the speed and direction are changed. The change of velocity will also produce inertial force, so I have reason to believe that it is the inertial force of the velocity that affects the direction of the inertial force that causes the walnut to move one after the other. And don't the two walnuts themselves have a tendency to move closer to each other? So, I don't think it's that the inertial forces in both directions are reversed, but that the velocity inertial forces are in the middle of the inertial forces in both directions.

Okay, Liuzifeng is coming, you are right.
