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
