ENERGY TOPIC TEST!!!
Solar
-Chemical Energy that Stores up energy from the sun ADVANTAGE: DOES NOT POLLUTES THE EARTH AND HAS ALOT MORE ENERGY THAN FOSSIL FUELS DISADVANTAGE: EXPENSIVE
Fossil Fuels
-Energy that comes ground the Earth's surface and takes millions of years to form ADVANTAGE:GIVES US ENERGY AND IS EASY TO USE DISADVANTAGE:POLLUTES EARTH AND DESTROYS EARTH AND CAN RUN OUT
Biomass
-Most common energy source ADVANTAGE: CAN BE RENEWED AND GIVES US ENERGY DISADVANTAGE: POLLUTES EARTH
Wind
-Renewable Energy Source that is all over the world ADVANTAGE: EVERYWHERE ON EARTH AND IS RENEWABLE DISADVANTAGE: EXSPENSIVE
7 forms of Energy
1.Chemical 2.Sound 3.Heat 4.Machanical 5.Nuclear 6.Radaint 7.Electric
Kinetic Energy (MOTION)
2 factors influence kinetic energy: 1. Velocity 2. Mass
Gas
Empty space, particles spread OUT and MOVE FAST
Non-Rewnewable Energy
Energy that CAN NOT be replaced or renewed
Renewable Energy
Energy that can be replaced or "renewed" (ADVANTAGES)
Gravitational Potential Energy
Energy that is off the ground and deals with height
Elastic Potential Energy
Energy that is stretched, pulled, or compressed
Transformation of Energy
Energy that travels to one form to another EXAMPLE: Mechanical----------->Sound Someone clapping their hands
The non-renewable energy
FOSSIL FUELS, and Nuclear
Convection
Liquids and Gases (EX) Ovens,heat, Earth, Water
Liquid
Losser position, move slightly faster, and has a definite volume
Fahrenheit Scale
First scale created. Freezing Point: 32 degrees Boiling Point: 212 degrees
Solid
Fixed Position, vibrates slowly, and has definite shape and volume.
Celsius Scale
Most common used scale. Freezing Point: 0 degrees Boiling Point: 100 degrees
Thermal Expansion
Particles spread out when heated
Conduction
Solids that are touching (EX) 3D objects
Temperature
The average kinetic energy (motion) of the particles. Scales are Fahrenheit Scale, Celsius Scale, and Kelvin Scale.
Power
The rate at which we do work Power= Work divided by time l---------l-------------l (Watt) (Joule) (seconds)
Law of Conservation of Energy
The that states energy can't be created or destroyed
Thermal Energy
The total amount of particles in a substance.
Work
The transfer of energy to one object to another Work=Force X Distance l--------l------- l (Joules) (Neutons) (Meters)
Heat
Thermal energy going from a warmer object to a cooler object
Radiation
Through empty space, no matter, and electromagnetic (EX) Heat, radiator, fire, sun
Kelvin Scale
Used by scientist. Freezing Point: 273 kelvin Boiling Point: 373 kelvin
The renewable energy
Wind,solar,geothermal,biomass, and hydroelectric
