Studied by 3 peopleFission
This is when atoms split and give off energy.
Joules
Work, like energy, is expressed in
Fossil Fuels
a nonrenewable: coal, natural gas, and petroleum.
Photosythesis
Plants use light energy to make new substances that have chemical energy.
gasoline
They are used to make kerosene, wax, and plastic.
Biomass
Organic matter such as plants, wood and waste that can burned to release thermal energy.
Electrical Generators
Convert the chemical energy in fossil fuels into electrical energy.
Renewable Resource
a natural resource that can be replaced at the same rate at which the resource is consumed.
Energy conversions
are more efficient when they use less energy.
Energy
The ability to do work
Kinetic Energy
The energy of an object that is due to the objects motion
Potential Energy
The energy that an object has because of the position, shape, or condition of the object
Gravitational Potential Energy
When you lift an object, you do work on it
Mechanical Energy
The amount of work an object can do because of the objects kinetic and potential energies
Thermal Energy
The kinetic energy due to the random motion of the particles that make up an object
Chemical Energy
This is a form of potential energy
Step 1 to energy conversion
Starting with coal which is a chemical & potential then burn it, Thermal which is (kinetic)
Step 2 to energy conversion
Burn water to create steam which is forced thru pipes in turbines making it spin and thats mechanical
Step 3 to energy conversion
Then go to the electricity
Step 4 to energy conversion
Then turn on the light (electrical) or blow dryer (thermal, mechanical, and sound)
Nuclear Energy
Energy that comes from changes in the nucleus of an atom
Fission
This is when atoms split and give off energy
Electrical Energy
The energy of moving electrons
Sound Energy
Vibrating objects transmit energy through the air around them
Light Energy / Radiant Energy
Energy produced by the vibrations of electrically charged particles
Energy Conversion
A change from one form of energy to another
Law of Conservation of Energy
states that energy cannot be created or destroyed (energy is never lost) but can be changed from one form to another (just changes forms)
Nonrenewable Resource
Is a natural resource that cannot be reused or replaced
Electrical Generators
Convert the chemical energy in fossil fuels into electrical energy
Renewable Resource
a natural resource that can be replaced at the same rate at which the resource is consumed
Solar Energy
sunlight is changed into electrical energy through solar cells
Hydroelectric Energy
falling water from a dam turns a turbine which is connected to an electric generator
Wind Energy
The kinetic energy of the wind turns blades of a windmill which turns an electric generator
Geothermal Energy
Thermal energy caused by the heating of Earths crust
Biomass
Organic matter such as plants, wood and waste that can burned to release thermal energy
