Yo-Yo Energy Return
The yo-yo trades height for spin and back again.
Teaching & key ideas
What you do: Drop and return the yo-yo while students watch the spin.
What students see: The yo-yo trades height for spin and back again.
Why it works: Gravitational energy becomes rotational kinetic energy and then returns.
Question to ask: Where does the falling energy go?
