How does a yoyo work?

it depends a imperial shaped yo yo's shape lets it roll back up immediately when u tug the string a butterfly shaped yo yo's shape lets it land on the string with unique tricks the bearing on both butterfly and imperial yo yo's are meant to stay at the center the bearing's smooth texture lets the string wold on to it when you throw the yo yo the bearing will make the yo yo spin the string will hold on to the bearing with out stop the yo yo from spinning then you simply tug the yo yo back up and catch it with your hand


What are the forces exerted on a yoyo hanging motionless on a string?

The forces exerted on a yoyo hanging motionless on a string are gravity acting downward and tension in the string acting upward. These forces are balanced, resulting in a state of equilibrium where the yoyo remains stationary.


What kind of simple machine is a yoyo?

A yoyo is a type of simple machine known as a pulley. It consists of a wheel and axle that, when a string is wound around it, allows for easy movement of the string up and down.


What are some cool science fair projects involving a yoyo?

Investigate the physics of yoyo tricks by analyzing the forces and energy involved in various tricks like "Around the World" or "Rock the Baby". Design an experiment to test the relationship between yoyo string length and spin time. Create a yoyo that utilizes alternative energy sources, such as a solar-powered yoyo or a wind-powered yoyo, and compare its performance to a traditional yoyo.


What is a yoyo made of?

A yoyo is typically made of two plastic or metal halves that are connected by a bearing or axle in the center. The material used for the body can vary, with plastic, metal, wood, and other materials being common choices for yoyo construction. The string used with the yoyo is usually made of polyester or cotton.

How do you hitch yoyo?

To hitch a yoyo, first, ensure you have a sleeper (the yoyo spinning at the end of the string). Then, while it's spinning, take the string between your thumb and forefinger and create a loop by wrapping the string around the yoyo. Pull the loop up and over the yoyo, allowing it to catch on the string. Finally, give a gentle tug to unwind the string and bring the yoyo back to your hand.


How do you do a long-sleeper trick on a yoyo?

Rub candle wax into the string to give you a longer rotation time. Also take some of the string twist out of the string so it has less braking action. Assuming that you're right handed, you get the yoyo spinning as fast as you can, then reach down with your right thumb and index finger to pick the yoyo up about 3 inches from the spinning yoyo itself. Your left hand thumb and index finger will form the bottom of a triangle, while your right hand's middle finger will form the top of the triangle of string. The yoyo is then swung in and ouy of the triangle of string. It takes some practice.

What pulls a yo-yo back to the top?

Centrifugal force. The yoyo is spinning rapidly on the downswing and when it hits bottom it returns climbing the string.

What is the point in yoyo gloves?

The point of yoyo gloves is to protect your hand from string burns and to create a smoother slide for the string. It also stops the build up of grease and dirt on your hands going onto your string.


How do you fix an un breakable yoyo string knot you break up the yoyo and you take off the string 4 another if the yoyo seems to be unbreakable the stick something not sharp to take the knot out?

ok,the way you posted is ok but be extra careful because any string can be cut so be carefu


Is knots in your yoyo string about jerry spenelli?

Yes. It is an autobiography.
