How does a yoyo work?

Answer 1

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

Answer 2

A yoyo consists of two disks connected by an axle. When you throw the yoyo downward, gravity pulls it down which creates tension on the string wrapped around the axle. When the yoyo reaches the end of the string, the tension causes it to spin, and the spinning motion helps it to wind the string back up when you tug on it.
