| battery | a device that converts chemical energy in electrical energy |
| Alessandro Volta | developed the first battery |
| electrode | a metal part of an electrochemical cell, which gains or loses electrons |
| electrolyte | a liquid or paste that conducts electric current |
| wet cell | an electrochemical cell in which the electrolyte is a liquid |
| dry cell | an electrochemical cell in which the electrolyte is a paste |
| series circuit | an electric circuit with a single path |
| parallel circuit | an electric circuit with multiple paths |
| friction | the force that one object exerts on another when the two rub against each other |
| aerodynamics | the study of force and the resulting motion of objects through the air |
| Bernoulli's Principle | as the speed of a moving fluid increases, the pressure within the fluid decreases |
| force | a push or pull |
| Newton | a unit of force |
| Newton's First Law of Motion | an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by a net force |
| Newton's Third Law of Motion | for every action, there is an equal and opposite reaction |
| Elijah McCoy | invented automated lubricant system |
| resistance | when you add a device to a circuit that slows down the electrons |
| scientific term for light bulb, fan, motor | load |
| magnetic field | the region around a magnet where the magnetic force is exerted |
| magnetic poles | the ends of the magnet |
| opposite poles | attract |
| same poles | repel |
| when the electrons take a "shortcut" that was not planned | short circuit |
| maglev stands for | magnetic levitation |
