Multiple Choice

What is the main difference between kinetic energy and thermal energy as described in the image?

• Kinetic energy is only found in living things, while thermal energy is found in non-living things.

• Kinetic energy refers to any moving object, while thermal energy specifically measures particle movement within substances.

• Kinetic energy is a form of thermal energy, while thermal energy is not related to movement.

• Thermal energy is the energy of light, while kinetic energy is the energy of sound.
