Energy

Imagine the world stood still and no one is moving. No work would be done and the possibility of change is just a distant fantasy. It would be a very boring place to live in, right? To be able to move and work, we need Energy.

Energy makes change and it is the ability to do work. Work, on the other hand, is the amount of effort or force used over the distance you have covered.

At the end of this webquest you should be able to differentiate the 2 kinds of energy and identify the different energy sources. 

In order for you to complete the given tasks, I have here some informations that can help you.

2 Kinds of Energy

• Kinetic Energy— is also known as the energy of motion. Anything that’s moving has kinetic energy. Whether you’re sprinting to reach your next class or riding a bike on your way home, you’re using kinetic energy.
• Potential Energy— is the possibility of kinetic energy. It is energy that is stored.

Energy Sources

• Natural Energy Sources
  • Fossil Fuels— composed mainly of Carbon and Hydrogen. It came from broken-down remains of life forms that died millions of years ago.

1. Coal— formed mainly from swampy forests that grew about 350 million years ago.
2. Oil— comes from the remains of plants and animals that lived in ancient seas.
3. Natural Gas— deposits that came from the same ocean organisms that created oil. It is thought to be formed when the deposits of dead matter reached very high temperatures.

• Nuclear Power— refers to the energy stored in an atom’s nucleus.
• Renewable Energy Sources— sources of energy that occur naturally and repeatedly in the environment or energy made from clean technology that won’t run out.
• Solar Power— the energy from the sun that won’t run out. Although this is a promising energy source, harnessing it efficiently is still a problem since the solar cells that trap this energy don’t create enough power.
• Wind Power— windmills are used to harness wind’s energy.
• Water Power— hydroelectric plants use the flow of falling water to turn turbines.
• Geothermal Power— energy from inside the Earth and comes to the surface as hot water or steam.
• Biomass— energy from plant and animal waste products.

Give what is being asked:

1. It is energy that is stored.
2. Energy that came from broken-down remains of life forms that died millions of years ago.
3. It refers to the energy stored in an atom’s nucleus.
4. Sources of energy that occur naturally and repeatedly in the environment or energy made from clean technology that won’t run out.
5. The energy from the sun that won’t run out.
6. It is known as the energy of motion.
7. It is energy from plant and animal waste products.
8. - 10. 3 kinds of fossil fuels

Energy is the ability to do work. it has two kinds: Kinetic and Potential energy. the 2 major categories of energy sources are Natural and Renewable Energy Sources. Nuclear power and Fossil fuels are under natural energy sources. Solar, wind, water, geothermal and biomass energy are under Renewable Energy Sources.
