Question

Eddie and Val observed the picture of an athlete running in a race. Eddie stated the picture shows potential energy being transformed to kinetic energy. Val stated that it shows chemical energy being transformed to mechanical energy. Which best explains who is correct?
Only Eddie is correct because the picture does not show a transformation that starts with chemical energy.

Only Eddie is correct because the picture does not show a transformation that ends with mechanical energy.

Both Eddie and Val are correct because chemical energy is a type of potential energy and mechanical energy includes kinetic energy.

Both Eddie and Val are correct because chemical energy is a type of kinetic energy and mechanical energy includes potential energy.


ITS NOT THE LAST ONE I GOT THAT ONE WRONG LAST TIME

Answer 1

The correct answer is:
"Both Eddie and Val are correct because chemical energy is a type of potential energy and mechanical energy includes kinetic energy."

In fact, chemical energy refers to the energy stored in the molecular bonds, so it is a form of potential energy. Moreover, mechanical energy is defined as the sum of kinetic and potential energy, so it includes kinetic energy (and since the runner is running, he's moving with a certain speed, so its initial potential energy stored in the muscles converted into kinetic energy).

Answer 2

Answer:

"Both Eddie and Val are correct because chemical energy is a type of potential energy and mechanical energy includes kinetic energy."
