physical science chapter 13

• ENERGY THE ABILITY TO DO WORK ( WORK IS THE
  TRANSFER OF ENERGY)
• KINETIC ENERGY THE ENERGY OF MOTION, UNIT
  IDENTICAL TO WORK JOULES
• KINETIC ENERGY DEPENDS ON AN OBJECT'S MASS AND
  VELOCITY
• KINETIC ENERGY INCREASES AS MASS INCREASES
• IT INCREASES EXPONENTIALLY WITH INCREASES IN
  VELOCITY
• EQUATION (Mass X Velocity 2) 2
• POTENTIAL ENERGY STORED ENERGY AVAILABLE TO DO
  WORK
• ELASTIC POTENTIAL POSSESSED BY COMPRESSED OR
  STRETCHED OBJECTS
• GRAVITATIONAL POTENTIAL ENERGY DEPENDS ON
  OBJECT'S HEIGHT
• WEIGHT 9.8 m/s2 x MASS
• GPE weight X height ( in joules)

• THE FIVE FORMS OF ENERGY
• MECHANICAL ENERGY THE PHYSICAL MOTION OR
  POSITION OF OBJECTS
• THERMAL ENERGY THE MOVEMENT OF THE MOLECULES OF
  AN OBJECT
• CHEMICAL ENERGY STORED IN CHEMICAL BONDS
  BETWEEN ATOMS
• ELECTROMAGNETIC ENERGY CAUSED BY THE MOVEMENT
  OF ELECTRONS
• INCLUDES LIGHT, ELECTRICITY, RADIO, MAGNETISM,
  RADIATIONS
• TRAVELS IN WAVES WHICH HAVE BOTH PROPERTIES
• NUCLEAR ENERGY STORED IN THE NUCLEUS OF THE
  ATOM
• FISSION THE SPLITTING OF LARGE URANIUM ATOMS
• FUSION PUTTING TOGETHER ATOMS TO MAKE NEW,
  LARGER ATOMS
• USED BY STARS 4 HYDROGENS FORM ONE HELIUM ATOM,
  ENERGY
• MOST POWERFUL FORM OF ENERGY

• ENERGY CONVERSIONS CHANGING ONE ENERGY FORM TO
  ANOTHER
• MOST FORMS OF ENERGY CAN BE CONVERTED INTO ANY
  OTHER FORM
• MOST COMMON CONVERSION KINETIC TO POTENTIAL
  ENERGY AND BACK
• EXHIBITED BY THE MOTION OF A PENDULUM
• MAXIMUM POTENTIAL AT THE TOP OF THE PENDULUM'S
  SWING
• MAXIMUM KINETIC ENERGY AT THE VERY BOTTOM OF THE
  SWING
• WATERFALL EXHIBITS THE CHANGE OF POTENTIAL TO
  KINETIC ENERGY
• LAW OF CONSERVATION OF ENERGY ENERGY CANNOT BE
  CREATED OR DESTROYED
• FRICTION ACCOUNTS FOR SOME LOSS OF KINETIC,
  CHANGES TO HEAT
• FRICTION IS THE REASON THAT EFFICIENCY CAN NEVER
  BE 100

• EINSTEIN STATED ENERGY COULD BE CREATED BY
  DESTROYING MATTER
• RESULTED IN THE DISCOVERY OF NUCLEAR FISSION AND
  FUSION
• DEMONSTRATED IN THE EQUATION E mc 2
• FOSSIL FUELS FORMED FROM ORGANIC MATERIAL
  MILLIONS OF YEARS OLD
• FUEL STORE CHEMICAL POTENTAL ENERGY
• FOSSIL FUELS FORMED BY COMPRESSION IN SEDIMENTARY
  ROCK
• COAL AND OIL FORMED BY DECAYED PLANT AND ANIMAL
  MATTER
• CHANGED BY PRESSURE AND TEMPERATURE OVER A LONG
  TIME
• UNRENEWABLE ENERGY WHICH PRODUCES GREENHOUSE
  GASES

• SUN IS THE SOURCE OF ALMOST ALL OF EARTH'S ENERGY
  
• NUCLEAR ENERGY (FUSION) IS CONVERTED TO
  ELECTROMAGNETIC ENERGY
• TRAVELS THROUGH EMPTY SPACE
• SUN'S ENERGY CAUSES WEATHER, SOURCE OF FOOD
  ENERGY, FOSSIL FUEL
• POWER HOW FAST WORK IS DONE
• EQUATION (WORK) / TIME OR (FORCE x DISTANCE) /
  TIME
• MEASURED IN WATTS (W), EQUAL TO "1 joule per
  second
• NAMED AFTER JAMES WATT (IMPROVED STEAM ENGINE)
  1800s
• kilowatt (kW) 1,000 W
• 1 horsepower 746 watts
• POWER ALSO THE RATE ENERGY IS TRANSFERRED FROM
  ONE OBJECT TO ANOTHER
• POWER IS NOT LIMITED TO THE MOVEMENT OF OBJECTS
• POWER EXISTS WHEN ENERGY IS TRANSFERRED OR
  CONVERTED
