6. which of the following is an example of energy changing forms?\n○ taking a nap.\n○ going for a run.\n○ using your cell phone.\n○ eating a big lunch.

Answer

Brief Explanations:

  • Taking a nap: The body conserves energy, no form change.
  • Going for a run: Converts stored chemical energy in the body to kinetic (movement) and thermal (body heat) energy, which is an energy form change.
  • Using your cell phone: While it does convert energy, the primary energy change is from battery chemical to electrical/light, but the most direct example of a biological/mechanical energy shift is running.
  • Eating a big lunch: Stores chemical energy, no immediate energy form change.

Answer:

Going for a run.
