What kind of energy transfers are these

  1. Feb 9, 2014 #1
    1. The problem statement, all variables and given/known data
    Sun to plant
    Worm eating a plant
    Bird eating a worm
    Human eating a bird
    Human throwing a ball up in the air
    Plant to coal
    Coal to a factory
    Factory to power lines
    Power lines to computer
    Sun to Rubber tree
    Rubber tree to factory
    Factory to ball (manufacture)

    3. The attempt at a solution

    Sun to plant - light energy
    Worm eating a plant - chemical energy
    Bird eating a worm - chemical energy
    Human eating a bird - chemical energy
    Human throwing a ball up in the air
    Plant to coal - chemical energy
    Coal to a factory
    Factory to power lines
    Power lines to computer - electric energy
    Sun to Rubber tree - light energy
    Rubber tree to factory
    Factory to ball (manufacture)

    Correct me if I'm wrong on these.

    Looks like you have the right idea, but a transfer involves going from one form of energy to the next, so I think you should rephrase your answers in the form of: (starting energy) to (ending energy).

    For example, the first one would sound better as: light energy to chemical energy

    Oh, thanks. Do you know if the ones i have so far are right? I think these two are chemical, but i may be wrong

    Coal to a factory
    Factory to power lines

    I have no clue about these two

    Rubber tree to factory
    Factory to ball (manufacture)

    What kind of energy is it when

    Human to a ball
    Coal to a factory
    Factory to power lines
    Rubber tree to factory
    Factory to ball (manufacture)

    With kinds of energy transformations is one familiar?
