Practice problem
When you go for a run, where does most of the energy that you're using go?
Running doesn't actually use any of your energy, it stays inside of you.
It is given away to the air around you, as it's forced to move while you do to take up the space of where you were previously.
It's burned and used up.
It becomes heat from the friction in your muscles and between your shoes and the road.
Type a concept, like “slope” or “photosynthesis”.
