The ability to do work Energy: Two types of Energy: Potential Energy Page 1 The ability to do work Energy: Two types of Energy: Energy of Potential Energy being stored Kinetic Energy motion When the fat lady sings
Page 1 Absolute Zero All molecular movement ceases- it is the lack of any energy Lowest possible temperature ever- only theoretical -459°F or -273°C or 0 kelvin Moleular Motion
Potential Energy stored energy EXAMPLES AT THE TOP OF A SKI SLOPE Page 1 Potential Energy stored energy EXAMPLES AT THE TOP OF A SKI SLOPE WATER BEHIND A DAM
THROWING A BOWLING BALL WATER FLOWING IN A RIVER Page 1 Kinetic Energy energy in motion EXAMPLES SKIING DOWNHILL THROWING A BOWLING BALL WATER FLOWING IN A RIVER
Energy Transformation Page 1 Energy Transformation energy in motion stored energy EXAMPLES SINGING LADY FALLS
Closed system- Energy can not escape or enter Page 1 Conservation of Energy- Energy can not be created nor destroyed, but transformed from one type to another Closed system- Energy can not escape or enter
ENERGY ALWAYS FLOWS FROM HIGH LOW or SOURCE TO SINK Page 1 Source- Sink- ENERGY ALWAYS FLOWS FROM HIGH LOW or SOURCE TO SINK Ex: Sun to Earth Where it comes from Where it flows (goes)
The Sun Earth’s Interior What is our main source of energy? Page 1 What is our main source of energy? What is our secondary source of energy? The Sun Earth’s Interior

Energy Transfer from Sun Page 2 Energy Transfer from Sun Electromagnetic energy is a type of energy that is radiated by the sun in the form of transverse waves
Electromagnetic Energy Page 2 ALL OBJECTS THAT HAVE A TEMPERATURE GREATER THAN ABSOLUTE ZERO EMIT (GIVE OFF) ELECTROMAGNETIC ENERGY ***Higher temperature more radiated energy*** amplitude ***Put this key concept at bottom of page 2***
Electromagnetic Energy Page 2 Transverse Wave- a wave that vibrates at right angles to the direction at which it is traveling
Parts of a Transverse Wave Page 2 Crest- top of a wave Trough- bottom of a wave Amplitude- height of a wave
Parts of a Transverse Wave Page 2 Wavelength-is the distance between two successive crests or troughs
Page 2 Frequency- is the number of waves which pass a certain point in a second The longer the wavelength, the lower the frequency The shorter the wavelength , the higher the frequency
The Electromagnetic Spectrum (EME) is a model of the different forms of radiation Page 2
All types of EME are similar: they travel to you in transverse waves Page 2 All types of EME are similar: they travel to you in transverse waves they travel at the speed of light are radiated

1. How are different types of energy told apart? Page 2
Radiation occurs in different forms identified by their wavelengths Page 2
Page 2
2. Which are more powerful- short wave or long wave energy? Page 2
Page 2 Short wave energy
3. What does UV rays do? They harm humans Page 2 3. What does UV rays do? They harm humans
4. Why is the ozone layer important? Page 2 4. Why is the ozone layer important? b/c they absorb harmful UV radiation
