About this item

  • 🪀It is played by holding the free end of the string known as the handle (by inserting one finger—usually the middle or index finger—into a slip knot), allowing gravity (or the force of a throw and gravity) to spin the yo-yo and unwind the string (similar to how a pullstring works).
  • 🪀The player then allows the yo-yo to wind itself back to the player’s hand, exploiting its spin (and the associated rotational energy). This is often called “yo-yoing”.
  • 🪀In the simplest play, the string is intended to be wound on the spool by hand; the yo-yo is thrown downward, hits the end of the string then winds up the string toward the hand, and finally the yo-yo is grabbed, ready to be thrown again.
  • 🪀One of the most basic tricks is called the sleeper, where the yo-yo spins at the end of the string for a noticeable amount of time before returning to the hand.
  • 🪀A yo-yo (also spelled yoyo) is a toy consisting of an axle connected to two disks, and a string looped around the axle, similar to a spool. It is an ancient toy with proof of existence since 500 BCE. The yo-yo was also called a bandalore in the 17th century.

Technical Details

 

Product description

When the yo-yo is first released, the gravity (and the throw) give it translational kinetic energy and necessarily, since the string must unwind, much of this energy is converted into rotational kinetic energy establishing the free movement of the yo-yo, and causing it to spin rapidly. As the yo-yo unwinds downward, it also converts potential energy from gravity to both translational agh energy in its rotation to overcome gravity all the way back up to the hand.
