Types of Energy
The Energy of Motion
Kinetic Energy
Describe the Transfer of Electrical Energy in a Lamp
Electrical Energy > Radiant (Light) Energy & Thermal (Heat) Energy
This form of energy is created through the use of the energy created by the sun.
Solar Energy
Solid form of Fossil Fuel - created by decayed plants and trees. Used for electricity and manufacturing.
Coal
What is the definition of conservation?
To prevent the destruction or permanent removal of a resource.
The Energy an object has based on its position or condition. Can be Elastic or Gravitational.
Potential Energy
Energy cannot be ____________ or ______________, it can only be _______________.
Created, Destroyed, Transferred
This form of energy is created through using corn farming bi-products such as husks and hulls to create energy
Biomass Energy
Liquid form of Fossil Fuel - produced by dead and decayed; heated and pressurized over millions of yeaars. Used for transportation and manufacturing.
Petroleum (Oil)
Why are Solar Panels not popular means of retrieving energy in homes?
They're too expensive to make.
Energy used for electricity created by the flow of water.
Describe the Energy transformation of the movement of a slinky.
When a slinky is stretched it has elastic potential energy and when it is coming back together or moving it has kinetic energy.
This resource uses the movement of air masses to turn turbines, that crank generators, to create electricity.
Wind Energy
Gaseous form of Fossil Fuels - used in heating, manufacturing, and electricity. - Odorless so chemicals are added to create smell.
Natural Gas / Propane
At what point does a roller coaster have the greatest potential energy?
At the highest hill along its track.
Form of energy that utilizes the movement of air to vibrate the eardrum.
Sound Energy
Describe the energy transfer that occurs in a car.
Chemical Energy > Thermal Energy > Mechanical Kinetic (Motion Energy)
What are 3 eco-friendly practices that you could follow?
1. Use reuseable shopping bags.
2. Ride your bike for short traveling distances.
3. Composting.
Created through the use of Uranium - highly radioactive and a fairly new source of energy.
Nuclear Energy
Heat and Pressure
Energy produced within the earth's surface used for heating and electricity.
Geothermal Energy
Explain the transfer of energy that occurs in a waffle iron.
Electrical Energy > Thermal Energy > Chemical Energy > Mechanical Kinetic (motion) Energy
What happens to a Renewable Resource if you use it?
It isn't affected. You cannot deplete a renewable resource - it is constantly renewed.
What are the major benefits/hazards to Non-Renewable Resources?
Benefits: Cheap, Easy to retrieve, and efficient to use to create energy.
Hazards: Polluting, Going to run out.
