Energy Video: Types, Transfer, and Conservation

In this video, we explore the concept of energy, including its definition, sources, transfer, and conservation. We discuss various types of energy such as kinetic, potential, thermal, chemical, electrical, magnetic, radiant, elastic, gravitational, sound, ionization, and nuclear energy. The video also covers the importance of conservation of energy and the use of fossil fuels for energy production.

  1. VIDEO DO NOW: Please write in your notebooks your opinion of the video and any questions you may have about the video. We will revisit this video / questions again tomorrow. TO DO today: Do Now Q (save for later) Activity Review HW

  2. INTRODUCTION • Walk around the room and examine the objects you see…. • Answer the questions on the page… WHAT IS THE CONNECTION BETWEEN THESE OBJECTS (keep it to your group when you figure it out…) • WE WILL REVIEW AT THE END OF CLASS

  3. What is the CONNECTION between all of those things? • TODAY you examined some objects and we determined that the connection was…… • ENERGY

  4. ENERGY VIDEO

  5. What is Energy? • The ability to do work • The ability to cause motion or change • WHERE DOES MOST OF THE ENERGY on Earth COME FROM?

  6. Photosynthesis or CHEMOSYNTHESIS • Chemosynthesis is making food by chemical energy instead of sunlight energy. • Used by EXTREMOPHILES vid • Like…. • Explained • Hydrothermal vents

  7. How is energy TRANSFERED? • What is meant by conservation of energy? • How is energy transferred between objects or systems?

  8. The Law of Conservation of Energy • states that energy can neither be created (produced) nor destroyed by itself. • It can only be transformed/transferred. Newton’s Laws • Newton’s Cradle • Professor risks his life for SCIENCE

  9. Types of Energy • KINETIC – energy in progress, a body in motion • Hover board

  10. Types of Energy • Potential - The potential to do work, or energy stored not being used yet. • Coal

  11. COAL • FOSSIL FUELS…. VIDEO • Fossil Fuels : Carbon based fuel made of ancient plant and animal remains. • Take MILLIONS of years to form • Natural Gas, Coal, Petroleum (oil) • SWPA was a SWAMP millions of years ago (~350 mya, Carboniferous Period) • COAL formed! • BITUMOUS COAL

  12. Types of Energy • Mechanical – Sum of kinetic and potential energies.

  13. VIDEO

  14. Types of Energy • Thermal – Energy required to change the temperature of something > Heat energy > transfers from warmer objects to cooler ones. video

  15. Types of Energy • Chemical - Energy by chemical reactions • Video

  16. Types of Energy • Electrical – Energy by electricity video2

  17. Types of Energy • Magnetic - potential energy by magnets or magnetic field • video

  18. Types of Energy • Radiant – electromagnetic radiation energy, including light • Light is wavelengths and differed wavelengths produce different colors. • White Light is a combination of all other colors • Video • 1

  19. ALBEDO • Radiant light that is not absorbed by the Earth but is reflected back to space.

  20. Types of Energy • Elastic – potential mechanical energy stored required to distort volume or shape. • Video • 1 • 2

  21. Types of Energy • Gravitational – potential energy due to the force of gravity caused by the attraction of all other masses to the mass of the earth • The potential to fall back to Earth • Video • 1

  22. Types of Energy • Sound – sound is produced by vibrations, the effect of mechanical energy propelled by oscillations (waves). • Video • Music

  23. Types of Energy • Ionization – the minimum amount of energy required to remove an electron from an atom. • Video

  24. Types of Energy • Nuclear energy - is the energy required to split a nucleus of an atom into its component parts • VideoThree Mile Island

  25. Nuclear energy
