When you eat a candy bar and then decide to go for a walk, energy transformations take place. beginning with the food energy in the candy bar, describe the forms of energy used and the changes in energy that occur as you decide to walk and as you do the walking?

》potential chemical energy
this is the stored chemical energy from the candy bar which you ate
as you eat it the sugars stored inside the candy go to your body
.The stored sugars are practically the food energy you
receive into your body

》kinetic energy
As you decide to walk you are moving, this energy is known as
kinetic energy.The kinetic energy is known as useful energy as
you are using it in a sufficient way .

》heat energy
When you are walking your body heats up a bit and you start
to sweat.This energy is known as wasted heat energy.
Heat from your body is wasted it is not being used sufficiently

Im not sure if this is exactly what you are after.
