| thermal energy | energy due to moving particles that make up matter |
| energy | the ability to cause change tor do work |
| conduction | the transfer of heat energy by one thing touching another |
| conductor | a material that readily allows heat to move |
| insulator | a material that limits the amount of heat that passes through it |
| convection current | a pattern of flowing heat energy |
| radiation | energy that is sent out in little bundles |
| thermal energy | total energy of all the particles in a body |
| insulator | limits the amount of heat that passes through it |
| radiation | one kind of energy that travels from the Sun through space |
| conductor | a material that allows heat to pass through it |
| convection current | a heated fluid rises and is replaced by a cooler fluid |
| conduction | the transfer of energy by one object touching another |
| temperature | a measure of the average amount of motion of an object's particles |
| static electricity | happens when positive and negative charges no longer balance |
| static | not moving |
| electric current | an electric charge in motion |
| resistance | material does not allow electric charges to flow through it easily |
| series circuit | electric charge can flow only in one path |
| parallel circuit | has two or more paths for the electric charge to follow. |
| magnetism | a force that acts on moving electric charge and magnetic materials that are near a magnet |
| magnetic field | goes out in all directions |
| electromagnet | a coil of wire with many loops through which an electric current passes. |
