Energy
What is energy? Learning Target: I will be able to define what energy is.
Learning target: I can state the unit to measure energy.
Learning target: I can give the correct definition of work.
Learning Target: I can solve work problems
100, 000 J Or 100 kj Learning Target: I can solve work problems Calculation practice formative
Learning target: I can correctly define the term power.
Learning target: I can state the unit used to measure power.
Learning target: I can solve equations for power.
POWER LAB
Learning target: I will be able to explain how machines make work easier.
150 x 3
IMA = LENGTH ÷ HEIGHT IMA = 12 IMA = 3 ÷ 4
Learning target: Simple machines increase mechanical advantage.
The more complex the pulley… The greater the mechanical advantage Learning target: Simple machines increase mechanical advantage.
What did you notice about the amount of wire you had to use as you made the pulleys more complicated?
LARGE FORCE……………SHORT DISTANCE SMALL FORCE……………LARGE DISTANCE Fx. D = Fx. D YOU CANNOT CHANGE THE WORK THAT NEEDS TO GET DONE!
There are three classes of lever…
Learning target: I can explain how machines make work easier.
Where does it all come from? Learning target: I will be able to give examples of common forms of energy.
All energy in our solar system starts with our sun
Is there only 1 type of energy?
No!!!!!!! There are many
Sound Light Motion Heat Gravitational Thermal Nuclear Electrical Chemical Stored mechanical Radiant
They all fall into two categories: Potential & Kinetic
Kinetic is movement energy
Potential is stored energy
Potential can be changed into kinetic and kinetic to potential. Learning target: I can give examples of common forms of energy.
Law of conservation of energy • Energy cannot be created or destroyed only changed from one form to the other. Learning target: I will be able to describe energy transfers and transformations.
Energy transfer is the transfer of energy from one thing to another. Kinetic to kinetic
Energy transformation/change : - is when energy is changed into another form. Gravitational potential to Kinetic and sound and heat.
Anything that can generate movement can make electricity!
Renewable? ?
Non Renewable? ? ?
Inexaustable / sustainable? ? ?
Energy Resource Diagrams
For this assignment you will show an energy resource starts/started with the sun………. . and ends with the production of electricity.
You will need to make a neat, colored drawing with descriptions.
You should include all of the important s-t-e-p-s along the way.
The following example cannot be used.
Fossil Fuels
Millions of years ago plants and trees used energy from the sun to grow.
The plants and/or animals were buried by sediments. Through the action of heat and pressure over millions of centuries, they were chemically changed. Coal, oil, and natural gas are the results.
At the power plant the coal is burned to heat water into steam. This steam is used to turn a turbine.
As the turbine turns the generator, electricity is produced.
Electricity is then sent to your home for your use!
You may choose from the following list of resources… Wind Solar Tidal Wave Biomass Hydroelectric-water Learning target: I will be able to LINK all sources of energy back to the sun.
Nuclear Energy Learning target: I will be able to simply describe nuclear fission and nuclear fusion. I will be able to evaluate both the positive and negative impact of nuclear energy. To get started go to my webpage and there are some links that may help……. YOU ARE WELCOME
Nuclear Fusion In nuclear physics, nuclear fusion is anuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted to photons (energy).
