2. Scientific Question Which source of energy helps the economy The best? Which source of energy helps the economy The best?

3. The “E” Solution by: Amir Lewis Grade 8

4. Did you know!!!! All roller coaster carts uses potential energy to generate their system All roller coaster carts uses potential energy to generate their system

5. Hypothesis If there is no more source of energy for the economy in the world will come destruction. If there is no more source of energy for the economy in the world will come destruction.

6. Solar energy Solar energy is the light and radiant heat from the sun that influences Earth’s climate and weather and sustains life. Solar power is sometimes used as a synonym for solar energy or more specially to refer to electricity generated from solar radiation.

7. Solar energy part: 4 Since ancient times solar energy has been harnessed for human use through a range of technologies. Solar radiation along with secondary solar resources such as wind and wave power.

8. Solar Energy Part: 2 Hydroelectric and biomass account for most of the available of flow of renewable energy on Earth. Solar energy technologies can provide electrical can provide electrical generation by heat engine

9. Solar energy part:3 photovoltaic means, space heating and cooling in active and passive solar buildings; potable water, distillation and disinfection, day lighting, hot water, thermal energy for cooking, and high temperature a process heat for industrial purposes.

10. Fast facts Kinetic energy is energy of motion. The kinetic energy of an object is the energy it possesses because of its motion. The kinetic energy of a point mass is given a formula

11. Potential Energy Potential energy is the same as stored energy. The stored energy is held within the gravitational field. When the objects us dropped. A lift motor from a roller coaster exerts potential energy when lifting the train to the top of the hill.

12. Potential energy part: 3 The higher the train is lifted by the motor the more potential is produced; thus forming a greater amount if kinetic, but it has a huge amount of potential energy, but it has very little kinetic energy

13. Vocabulary words kinetic- caused by motion Energy-capacity of doing work, sich as moving an object. Solar-any substance that comes from the sun

14. Kinetic Energy The word “kinetic” is derived from the Greek word meaning to move, inand the word “energy” is the ability to move something.

16. Conclusion Based on my conclusion, the best source of energy for the economy would be solar power. The reason why I chose this source for my conclusion was because, potential energy is used for pulling or operating big machines.
