Answer:
1. Click here to access an interactive simulation where you will explore the transfer and transformations of different types of energy that you have learned about in this lesson.
2. Click the systems box, and then select the energy symbols box. This will allow you to see the movement of energy and its type in the system.
3. Under the bike the person is riding, drag the blue rectangle to the right to start the system.
4. The chemical energy in the person's body is transformed into
✔ mechanical energy
when they peddle the bike, causing the generator to rotate. Some energy in the bike wheel is lost to
✔ thermal energy
. The generator produces electricity, which heats the water, causing it to produce thermal energy in the form of steam. When the person's chemical energy runs out, how do you replenish it?
✔ by feeding them food
5. Change the initial energy source to sun, the intermediate energy source to the solar panel, and the final energy source to the windmill. In this system,
✔ light energy
is produced from the sun and transformed into electricity in the solar panel. Both of these types of energy are considered forms of
✔ electromagnetic energy
. The result of this system is that the windmill produces mechanical energy.
6. Try a few more scenarios, choosing different initial, intermediate, and final energy sources. Observe places where energy is transformed and lost. Creating systems with the least amount of energy is important in engineering design.
