Energy Types

Slide 1 - Diapositive

This lesson
  • Recap
  • 2.3 Energy types
  • Working independently

Slide 2 - Diapositive

Learning goals
  • Make a list of the nine types of energy
  • Give examples for each type of energy
  • Name the two categories of energy  (kinetic and potential energy)
  • Explain what is meant by energy transfer

Slide 3 - Diapositive

Recap
Exercise
Step 1)Discuss with your neighbour what we covered about energy so far

Step 2) Go through the book 

Slide 4 - Diapositive

  • Energy is the ability to do work

  • The unit of energy is Joule (J)

  •  All work requires a source of energy

Slide 5 - Diapositive

  • The sun is the source of all energy in the solar system

  • Our energy source is food — The energy in food comes from sunlight, which gets converted into chemical energy through photosynthesis. 



Slide 6 - Diapositive

  • Fossil fuels — are made of animals and plants that passed away millions of years ago, which got buried under many layers of earth.

  • Green energy

Slide 7 - Diapositive

 5 Sources of green energy
  • Solar
  • Wind
  • Hydro
  • Geo-thermal
  • Biomass

Slide 8 - Diapositive

2.3 Energy Types

Slide 9 - Diapositive


Exercise

1) Make a list of the 9 types of energy 
described in paragraph 2.3

2)  What are the two categories of energy

Slide 10 - Diapositive

1) Make a list of the 9 types of energy described in paragraph 2.3
  • Chemical potential energy
  • Gravitational potential energ
  • elastic potential energy
  • kinetic energy
  • thermal energy
  • electric energy
  • light energy
  •  sound energy
  • nuclear energy

Slide 11 - Diapositive

Many forms of energy exist, but they all fall into two basic categories:
Potential energy ( stored energy) 
Kinetic energy ( energy in moving objects)

Slide 12 - Diapositive

2) What are the two categories of Energy?
Potential energy
(stored Energy)

  • Chemical Energy
  • Gravitational energy
  • Elastic energy
  • Nuclear energy
Kinetic energy
(Energy being used)
Energy of moving objects
  •  Kinetic energy
  • thermal energy
  • electric energy
  • light energy
  • Sound energy
