Definition | Term |
---|---|
Energy of moving electrons or electric charges | Electrical energy |
The ability to do work (mechanical, chemical, electrical, heat, light, and sound) | Energy |
Energy in the form of waves that can travel through an empty space | Light energy |
Work done for something that is moving | Mechanical energy |
Energy from vibrations | Sound energy |
Energy of heat | Thermal energy |
Energy from the sun | Solar energy |
Not easily becoming hot | Heat resistant |
a device that uses magnets to change mechanical energy into electricity | Generator |
the direction the electricity is moving | Electric Current |
an electrical safety device that can stop the current from flowing or shuts off power | Fuse |
a closed circuit in which a current divides into two or more paths; if one light goes out, others stay on | Parallel Circuit |
a closed circuit in which the current follows one path; if one light goes out, they all go out | Series Circuit |
electricity from a battery, solar, cell, fossil fuels or wind generator | Source/Cell |
an electrical current through which current can flow in an uninterrupted path | Closed Circuit |
an electrical current through which current can flow that is NOT complete | Open Circuit |
a wire that a current flows through | Path |
turns a circuit on and off | Switch |
continuous or steady movement of electricity | Flow |
the bouncing back of light waves off a surface | Reflection/Reflect |
the bending of light waves as they move through one medium into another | Refraction/Refract |
a glass or transparent object that bends light that separates white light into a spectrum of colors | Prism |
when light waves move through a material | Transmit |
a substance or material that makes it possible for the transfer of energy from one location to another | Medium |
to soak up | Absorb |
not allowing light to pass through | Opaque |
transmits some light and absorbs some light | Translucent |
materials that let light pass through them; absorb very little light | Transparent |
a piece of glass or other transparent substance (clear) with curved sides for concentrating or dispersing light rays | Lens |
