Motion & Energy
A force that holds back the movement of an object
What is friction
Vibrations that travel through materials from a source.
What is sound
This substance expands as it freezes.
What is water
This is the other name for electrostatic energy.
What is static electricity
The names of the two poles of a magnet.
What is the North pole & the South pole
Energy made from sources that don’t run out such as solar energy, wind energy, and hydropower.
What is renewable energy
Sound travels best through this state of matter.
What is a solid.
These are the 3 things a fire needs to ignite.
What is oxygen, heat, & fuel
A protective shield against the flow of electrons.
What is an insulator
This is a black rock with a shiny surface made of iron and oxygen.
What is magnetite
Forms of energy that come from animals and plants buried long ago.
What are fossil fuels
This is the mnemonic device used to remember the colors in the electromagnetic spectrum.
What is ROY G BIV
This type of heat energy occurs when the heat source and the heat sink are connected through matter. It travels best through a conductor.
What is conduction.
This is a circular path that starts and finishes at the same place.
What is a circuit
The region around the magnet that produces a magnetic force.
What is a magnetic field
A substance that reduces friction such as water, soap, and oil.
What is a lubricant
This is one of the two types of invisible light.
What is ultraviolet or infrared
This type of heat energy is the movement of warmer fluids to cooler regions such as in a pot of water or the sea.
What is convection
This is what we call facilities that generate electricity.
What are power plants
Any magnet powered by an electric current and the field disappears when the current is turned off
What is an electromagnet
A force that acts on a body moving in a circular path and is directed toward the center around which the body is moving
What is centripetal force
It happens to light when it enters a different medium such as liquid.
What is refraction
This type of heat is transferred through electromagnetic radiation. An example would be fire, sun, or microwave.
What is radiant heat
The name of the person who created the first battery.
Who is Volta
Tiny areas all over a magnet that work as individual magnets.
What is a magnetic domain
