the movement of energy through space as waves | radiation |
the force that pulls objects toward each other | gravity |
the force between two surfaces rubbing against each other | friction |
energy that is stored in an object | potential energy |
how high or low a sound is | pitch |
energy sources which are not based on burning of fossil fuels or the splitting of atoms | alternative energy |
to pass or cause to pass through space or through a material | transmitted |
a change from one form to another without turning into a new substance | physical change |
enery in form of heat from melted rock deep below Earth's surface | geothermal energy |
a material that does not let heat, electricity, or sound energy pass through it easily | insulator |
a complete circuit, allowing the flow of electricity to flow through. (the device starts working) | closed circuit |
to become absorbed in liquid: to make a solution with another substance | dissolved |
a change in the position of an object | motion |
a force that pulls magnetic materials across a distance | magnetism |
to take something up or in: to soak up a liquid or take in nutrients or chemicals gradually | absorb |
a push or pull | force |
the ability of an object or substance to allow heat, electricity, or sound pass through it | conductivity |
forms that matter can take- solid, liquid, or gas | states of matter |
the structure, feel and appearance of something | texture |
a force that causes floating. It is the ability of a liquid or gas to cause less dense objects to float or rise to the surface | buoyancy |
a particle of matter made of two or more atoms joined tightly together | molecule |
the point(temperature) at which a solid changes to a liquid | melting point |
the rapid back and forth movement that produces sound | vibrate |
the bending of light rays as they move from one material into another material | refracted |
the enery of moving particles in a substance (also called heat energy) | thermal energy |
the material, or stuff, that everything is made of | matter |
a form of energy produced by vibrating objects | sound |
when one or more substances change into one or more new substances with different properties than the original substances. Baking soda and vinegar make a chemical change. | chemical change |
any material that allows an electric current to pass through it easily | conductor of electricity |
the temperature at which a substance changes from a liquid to a gas | boiling point |
to change from a liquid to a solid when temperature drops | freeze |
a measure of the pull of gravity on an object | weight |
the amount of space that an object or substance takes up | volume |
the amount of matter in an object or substance | mass |
to draw objects nearer (the pull of a magnet) | attracted |
the ability of a mineral to resist being scratched | hardness |
a quality or attribute, especially one that serves to define or describe something | physical properties |
not changing; stable; not moving | stationary |
the temperature at which a substance changes from a liquid to a solid | freezing point |
to allow substances to pass through (like water going through a sponge) | permeable |
the process by which moisture in the air changes to liquid or solid form (rain, clouds, or snowflakes) | condensation |
when a substance changes from a solid to a liquid | melting |
energy of motion | kinetic energy |
the ability to do work | energy |
a form of energy that travels in waves and can move through empty space where there is no air | light energy |
to prevent or reduce the passage of heat, electricity, or sound into, from, or through something | insulate |
energy from the sun | solar energy |
a combination of two or more substances that do not form a new substance | mixture |
when a liquid is so hot that it changes to a gas | boiling |
a mixture with one substance spread out so evenly in another substance that you cannot tell the two substances apart | solution |
a curved piece of clear glass, or plastic that bends light rays | lens |
a form or energy that is felt as temperature | heat energy |
