Yo-yo: Not just a toy, it's one of the most fancied, difficult, and ornamental hand-to-hand sports in the world. Some people say that yo-yo is an educational toy, but in my eyes, yo-yo is by no means comparable to educational toys.

Yoyo is a word that is not unfamiliar to everyone, but it is often understood as a childish toy. After many years of continuous innovation and development, yo-yo is becoming a popular hand-to-hand sport all over the world.

Modern competitive yoyos are equipped with sophisticated bearing systems and highly efficient systems that can rely on the user's skill to pull off a variety of incredibly difficult tricks. Practicing yo-yo skills is in itself challenging the limits of one's technique; The process of practice itself is a process of repeated defeats in order to break through the limits.

Because each golfer's style and self-created style are different, there are many types of yo-yo technical styles, which can be said to be a sea of technology.

The way yo-yos are played professionally is very different from what is shown in some TV dramas. In professional competitions, contestants need to cooperate and combine countless tricks into a set of technical performances within the specified time. The referee will score the players according to the difficulty, ornamentality, and fluency of each movement, and count the accumulated points as the final score of the players.

The technical performances of high-level yo-yo players can even connect countless shocking technical tricks and show them to the audience in one go, so they are also very highly ornamental, dizzying and never tired of watching.

Therefore, it can be said that yo-yo is not only a toy that goes up and down, it is definitely a fancy, the most difficult and the most ornamental hand skill sport!

It is a kind of toy, which is loved by many people of different ages, and it can also be said to be a kind of finger movement, you can go to search to see, and the fancy can make you stunned.

The yo-yo stops at its lowest point and spins at high speed. So why did you pull it up as soon as you raised your hand? It seems amazing, but it's actually very simple.

Because of the friction of the cotton thread, when the person raises his hand, the cotton thread is no longer in a straight state, but the ball is spinning. First, due to the friction of the ball shaft with the wire, the thread is rolled up in a short section and fixed on the shaft. As long as the coefficient of friction is large enough, the ball spinning at high speed can roll up more lines, and the final effect is to complete the conversion of potential energy and return the ball to the hand.

To put it bluntly, the essence is that there is a little bit of friction at the beginning, and if it is an absolutely smooth line, it is impossible for the ball to return to the hand.

At the same time, the answer to the original answer of BS is kinetic energy to potential energy, which is obviously the conversion of rotational potential energy to gravitational potential energy.

Centrifugal force and then continue to roll by the bearing.

The clutch is to throw off the spring by inertia, and if it is slow to a certain extent, it should retract the spring due to lack of strength, but the yoyo ball is still spinning, and it goes up with the rope.
