Homework Help: 3 Simple Energy Question

  1. Sep 21, 2010 #1
    I need to study for my test and know the answer to these questions.

    a. List five different types of energy forms in a bike or its rider.
    b. Describe how one of these energy types is transformed?
    c. What is a dynamo and how does it work?

    Tell me what i did wrong. ( if i did ) . I am not sure if it is correct.
    2. a. kinetic and sound energy.
    c. Dynamo is an instrument on a bike that is used to produce electrical energy. A magnet is attached to the centre of a wheel (this magnet spins with the wheel) and a coil of copper(cu) surrounds it (does not move). The end of the copper coil is attached to a light usually on the handle bars. As you push on the pedals and make the wheels move, a current is produced that turns the light on.
