What is Energy?
The ability to do work
Energy
The name of devices used to capture the sun's energy
solar panels
A device that stores chemical energy and converts it directly into electrical power
Battery
before wind turbines, cultures used this device to turn wind into energy. We built one yesterday.
Windmills
The name of the nuclear bombs dropped during WW2
little boy and fat man
energy that causes motion
kinetic energy
The element that the sun is mostly made of
Hydrogen
the outer shell of atoms that create electricity
electrons
A place where water is pushed up to the surface of the earth, creating pools of warm water
a hot spring
the element that is used for nuclear energy plants today
uranium
elastic energy
Energy that is stored, ready to be used
Potential Energy
electricity that is not in a current
static electricity
What causes wind?
Hot air rising
the nuclear reaction that causes the sun to shine
nuclear fusion
thermal energy
Energy caused by atoms bumping into each other quickly
Heat
Electricity created in clouds by water and snow
lightning
The device that uses rotational energy to create electricity
turbine
The process of breaking apart complex atoms into simpler ones. This is the technology behind current nuclear power plants.
Nuclear Fission
the unit used to measure kinetic energy
Joules
Light particles that are released by stars. Used to power solar panels
Photons
The Element used in small batteries. It is mined in China and South America.
Lithium
Geothermal energy uses what element to power its turbine?
Water
When an unstable atom's nucleus breaks down by giving off energy and radiation
radioactive decay
