ENERGY VOCABULARY
ELEC. CURRENT VOCABULARY
100
In science, this is the ability to do work or cause a change.
What is energy?
100
This is the transfer of heat between objects that are in contact. For example, how a stove heats a pan.
What is conduction?
100
This is the flow of electrical charges through a material.
What is current?
100
This is the wave of vibrations that spreads from its source.
What is sound?
100
This is material through which an electric charge can move easily.
What is a conductor?
200
Name 4 forms of energy.
What is sound, light, electricity, and magnetism?
200
This is the transfer of heat by a moving liquid or gas. For example, cool water sinks under warm water.
What is convection?
200
What material resists the flow of an electric charge, and as current moves through this, some of the electrical energy changes to thermal energy.
What is a resistor.
200
Light is a form of this, which is a combination of electrical and magnetic energy.
What is eletromagnetic radiation?
200
These are strong resistors that can stop most electrical currents.
What are insulators?
300
This kind of energy is due to motion, and in a moving object, depends on its speed and its mass.
What is kinetic energy?
300
This is the transfer of heat by electromagnetic waves. For example, the sun warming a greenhouse.
What is radiation?
300
Name the parts of a circuit.
What are a battery, a switch, an insulator, a conductor and a resistor?
300
This is the total of all the kinetic and potential energy of the atoms in an object.
What is thermal energy?
300
This is the map of a circuit, and this is a measure of the electrical force provided by an energy source.
What are a circuit diagram and a volt?
400
This kind of energy is sometimes called "stored energy" because it may not cause any changes now, but could cause changes in the future.
What is potential energy?
400
These are the 3 ways that heat moves: 1) involves objects that are touching; 2) involves the movement of liquids or gases; 3) involves waves.
What is conduction, convection and radiation?
400
This kind of circuit has more than one branch or pathway. What has the most complicated circuits?
What is a parallel circuit and what are computers?
400
Types of electromagnetic radiation that have wavelengths that are shorter than those of visible light.
What is ultraviolet, X-ray, and gamma ray radiation?
400
These are formed by a current flowing through a coiled wire in a circuit, and are magnets that carry an electrical current.
What are electromagnets?
500
What type of potential energy does a match have, and what type of potential energy is found in the nucleus of an atom.
What is chemical energy and nuclear energy.
500
This flows between materials that have different temperatures, and naturally flows from warmer substances to cooler ones.
What is thermal energy?
500
Who experimented with and discovered many things about electricity in 1899?
Who is Nikola Tesla?
500
All stars give off this, and these are used for radios, television and astronomy.
What is radio waves?
500
These can be used as types of insulators.
What are rubber, plastic, glass and dry cotton?
