A nuclear energy plant produces energy through nuclear fission. The nuclear energy is converted into (potential, chemical, electrical, mechanical, electric, thermal) energy. The Ferris wheel operator pushes the "start" button to set the wheel in motion. This is an example of (potential, chemical, electrical, mechanical, electric, thermal) energy being transformed into (potential, chemical, electrical, mechanical, electric, thermal) energy. The whole Ferris wheel begins to move as (potential, chemical, electrical, mechanical, electric, thermal) energy is converted to (potential, chemical, electrical, mechanical, electric, thermal) energy. (potential, chemical, electrical, mechanical, electric, thermal) energy of the Ferris wheel in motion is converted to (potential, chemical, electrical, mechanical, electric, thermal) energy to light up the seats with LED bulbs.
