Energy transformation when dropping a yoyo?

Answer 1

Potential - Kinetic - Potiential again

as you drop the yo yo, the potential energy it had at its height is converted to kinetic energy. as it starts to come back up, it is converted back to potential energy

Answer 2

When dropping a yo-yo, potential energy is converted into kinetic energy as the yo-yo falls. The potential energy from gravity pulling the yo-yo downward is transformed into the motion energy of the yo-yo as it accelerates toward the ground.
