ENERGY, ELECTRICITY, AND MAGNETISM VOCABULARY

 

Atom

 

The smallest part of a substance that can exist and still retain the properties of that substance.

Chemical energy

Energy stored in the chemical bonds of molecules (Form of Energy).

Conduction

 

The transfer of heat (or electrical) energy through a substance or from one substance to another by direct contact of atoms or molecules.

Electric circuit

Continuous path that can be followed by charged particles.

Electric current

The flow of charged particles from one place to another.

Electrical energy

Energy of electrical charges as a result of their position or motion (Form of Energy).

Electricity

A general term for the physical phenomena that arise from the interaction of electric charges.

Electromagnet

A strong magnet that can be turned on and off.

Electron

The negatively charged particle that moves around the nucleus of an atom.

Energy

The ability to cause matter to move or change (Ability to do work).

Energy transformation

When energy changes from one type to another.

Gravity

The force of gravitational attraction on or near the surface of a celestial body.

Heat energy

 

The energy of a material due to the random motion of its particles. Also called thermal energy. The word "heat" is used when energy is transferred from one substance to another (Form of Energy).

Kinetic energy

Energy of motion/Action (Form of Energy).

Law of Conservation of Energy

Energy cannot be created or destroyed - only changed from one form to another.

Magnetic domain

A region in which the magnetic fields of all atoms are lined up in the same direction.

Magnetic pole

The ends of a magnetic object, where the magnetic force is strongest.

Magnetism

The field of force produced by a magnet or an electric current.

Mechanical Energy

Energy an object has because of its motion or position (Form of Energy).

Neutron

Particle with a neutral charge located in the nucleus of an atom.

Nucleus

The core at the center of every atom.

Parallel circuit

Electrical circuit arranged so that current passes through more than one pathway simultaneously.

Potential energy

The stored energy of a body because of its position (Type of Energy).

Proton

Positively charged particle in the nucleus of an atom.

Series circuit

An electric circuit in which the current passes through only one pathway.

Short circuit

An electrical connection that allows current to take an unintended path.

Solar energy

Energy from the Sun in the form of light and heat energy.
