Worked Solution
Step 1: Winding the toy stores elastic potential energy in the spring.
Step [2-9]: When released, the spring unwinds, converting that energy into motion (kinetic).
Step [2-9]: Friction converts some energy into heat and sound.
Correct answer: Elastic potential energy → Kinetic energy + Heat + Sound
