Types of Energy
This type of energy comes from heat and moves from warmer to cooler objects.
Thermal energy
A back-and-forth movement that starts a wave.
Vibration
This type of resource can be replaced or reused quickly
Renewable resource
Heat moves through direct contact.
Conduction
The ability to do work or cause change
Energy
Explain how energy from the Sun can turn into electricity that powers a lamp in your home
Sunlight → solar panels convert light into electrical energy → wires carry electricity → lamp turns electrical energy into light energy.
Energy made by vibrations traveling through air, water, or solids.
Sound energy
The distance from one wave to the next.
Wavelength
This type of resource takes millions of years to form
Nonrenewable resource
Heat moves through liquids or gases as warm air rises and cool air sinks
Convection
To save or use less energy
Conserve
This energy is caused by moving electric charges and can change into other forms.
Electrical energy
How tall a wave is
Amplitude
Coal, oil, and natural gas are examples of this.
Nonrenewable resources
Heat moves through waves, like sunlight.
Radiation
Energy that can change from one form to another, such as electricity to light or sound.
Electrical energy
This energy travels in waves and can move through space without a medium.
Light energy
Waves that do not need a medium to travel.
Light waves
Sunlight, wind, and water are examples of this.
Renewable resources
The type of heat transfer happening when a metal spoon gets hot in soup.
Conduction
The type of energy you feel from the Sun.
Light energy or radiation
(Daily Double!) Question: Name two forms of energy that can travel in waves
Sound and light energy
The number of waves that pass a point each second.
Frequency
$500 (Daily Double!) Question: Name one renewable and one nonrenewable resource and explain how they’re used to create energy
Wind (renewable) turns turbines; coal (nonrenewable) is burned for electricity.
Warm air from a heater rising through a room is this kind of heat transfer
Convection
A wave property that determines how loud a sound or how bright a light is.
