Electricity
| Term | Definition |
|---|---|
| gravity | a force that exists between any two objects that have mass; the greater the mass the greater the force; the closer the objects the greater the force |
| weight | the force of gravity on an object; varies by the mass of the planet or moon you are on |
| spring balance | a type of weighing scale. It consists of spring fixed at one end with a hook to attach an object at the other. The scale markings on the spring balance are equally spaced. It cannot measure mass, only weight. |
| increased mass of a planet means, _______________ weight of an object on that planet | increased |
| satellites | a natural or artificial object that revolves around another object in space |
| orbit | the circular path of an object as it revolves around another object |
| magnet | an object with a north and south pole that produces a magnetic field |
| magnetic field | a set of lines that defines the motion of charged particles near a magnet; can be created when an electric current flows through a wire |
| attract | the action between two opposing magnetic poles |
| electromagnet | a metal object that acts as a magnet when an electric current moves through it |
| current | the movement of electric charges through a material; the speed at which electric charges move through a material; the movement of liquid through a passageway or through another other liquid |
| produce a current with a magnet | spin a magnet around inside a coil of wire |
| mechanical energy | energy that an object has because of its motion or its position |
| electrical energy | the ability to do work by movement of electric charge |
| chemical energy | the energy that is stored in the bonds between atoms |
| static electricity | electric charges that build up on an object; extra electrons and a negative charge; maybe increased by friction, dryness, synthetics or plastics |
| stages of static shock | surfaces contact, excess charge builds, negatively charged surface come to a conductor, charges discharged, static charges neutralized |
| friction | a force that opposes the motion of a body across a surface or through a gas or liquid |
| induction | the process by which a body having electric or magnetic properties produces magnetism, an electric charge, or an electromotive force in a neighboring body without contact. |
| conduction | the transfer of heat energy within an object, or between objects that are directly touching each other, due to collisions between the particles in the objects |
| magnetic field | a region in space near a magnet or electric current in which magnetic forces can be detected |
| magnetosphere | region around a planet or star that encompasses its magnetic field |
| Northern Lights; auroras | caused by electrons from solar winds. They are attracted to the poles by the magnetic fields found there. They mix with gases in the atmosphere, causing the gases to glow. Solar flares can also cause them to appear. |
