Standard Science Primary 6 Energy

Study the diagram of a toy car powered by a wound-up spring. What is the main energy conversion when the car is released?

A Kinetic energy → Elastic potential energy
B Gravitational potential energy → Kinetic energy
C Chemical potential energy → Kinetic energy
D Elastic potential energy → Kinetic energy
Show Worked Solution

Worked Solution

Step 1: Winding the spring stores elastic potential energy. Step [2-9]: Upon release, the spring unwinds, moving the car. Step [2-9]: The stored energy is converted into kinetic energy.

Correct answer: Elastic potential energy → Kinetic energy
