Unit 3
What is an Electric Charge?
What is the property that leads to electromagnetic interactions between the particles that make up matter.
What are neutrons, protons, and electrons?
What are the subatomic particles that make up an atom?
What is an ion?
What is an atom that has an overall positive or negative charge?
What is an electric force?
What is the force that any two charged objects exert on one another?
What is the distance between objects?
What is something that affects the electric force, magnetic force, and gravitational force?
What is repel?
What is the behavior of objects that have similar charges?
What is attract?
What is the behavior of two objects with opposite charges?
What is charging by friction?
What is the rubbing of two objects together that causes electrons to transfer between the objects?
What is static electricity?
What is the buildup of electric charge on an object?
What is induction?
What is the rearranging of charges within an object without touching it?
What are conductors and insulators?
What are two materials that are used to make electric wire? Conductors allow electric charges to flow, while insulators do not allow charges to flow.
What are semiconductors?
What is a special class of materials that conduct electric charge better than insulators but not as well as electrical conductors?
What is DC and AC?
What two types of ways do we get electricity? DC is direct current which flows one direction, while AC is current that flows both directions.
What is Amperes and electric current?
What is the rate of flow of electric charges through a wire?
What is voltage?
What is the amount of work required to move each unit of charge between two points?
What are size of the wire, the length of the wire, and the temperature of the wire?
What are three things that affect the resistance of a wire?
What are a series circuit and a parallel circuit?
What are two circuit types that are both electric circuits? Series has one path, while a parallel has two paths.
What is a GFCI?
What is a type of circuit breaker that are built into outlets?
What are the magnetic force?
What is the force that results from spinning electric charges inside of magnets?
What are magnetic fields?
What are the domains?
What is the alignment of the atoms that line up and allow a magnet to be created?
What are Ferromagnets, electromagnets, and temporary magnets?
What are three types of magnets, or materials that can be made into magnets?
What is a North seeking pole, or a South Pole magnet?
What causes the Arrow in a Compass to point toward the North pole on Planet Earth?
What are the solenoid (current in a wire), a battery, and a piece of iron?
What are the parts of an electromagnet?
What are generators, electric motors, galvanometer, and MRI machines?
What are some common things that contain electromagnets?
