Necklace and Accessory Holder

Rotating swing rides

at amusement parks

work the same way

your necklace holder

works. When the ride

spins around, the

chairs ﬂy outward and

upward due to the

forces acting on them.

Hang necklaces from

the hooks. What

happens when you

turn the crank?

Done!

Why do the necklaces ﬂy outward when the

necklace holder is turned? When a car goes

around a corner quickly or sharply, you feel what

is called a force push you toward the outside of

the corner. A force is simply a push or a pull. As

the necklace spins around on the rotating holder,

from its perspective, it experiences a force

that pushes it outward, called the centrifugal

force. But then why does the necklace not ﬂy

oﬀ the holder? This is because the necklace

also experiences another force, called the

centripetal force, toward the center that keeps

it on its circle path. If there were no centripetal

force, then the necklace would just ﬂy oﬀ in a

straight line.

If you don’t have a few

necklaces to hang on the

holder, you can make

some using the string and

the plastic building pieces

as beads.
