Forms of Energy
What is energy?
Energy is the ability to cause motion or create change.
What produces sound?
Vibrations
What is light energy.
Energy that makes things visible.
What is heat?
A form of energy that changes temperature.
What is a conductor?
A conductor is a material that allows the flow of energy to pass through.
Name three forms of energy.
Mechanical (Motion)
Electrical
Light
Thermal (Heat)
Sound
What is pitch?
Name a source of light energy.
Sun or light energy
How does heat move?
From hot objects to cold objects.
Give an example of a good conductor?
Copper, aluminum, metal, etc.
What type of energy is produced by moving objects?
What's an example of a high pitch sound?
A bird chirping
What happens when light hits a mirror?
It reflects
What is conduction?
The transfer of heat through direct touch.
What is an insulator?
A material that stops or doesn't allow energy to pass through.
How can electrical energy be transformed?
It can be transformed into light, heat or sound.
How does the volume of a sound change?
How can light be used to create heat?
Light energy can be absorbed by materials warming them up.
What happens to ice when it's places in a warm room.
The ice melts when the heat flows from warm air to the cold ice.
What is a good example of an insulator?
Rubber, wood, fabric, etc.
What is the energy called that comes from the sun.
(Heat and Light)
What happens to sound in the water compared to air.
Sound travels faster in water than in air.
What is refraction?
The bending of light
What is convections?
Heat transfer through air or water.
Why do we use insulators in electric wiring?
It will not allow energy to pass through so that you can't be shocked.
