Concept 1 Force Fields

Question 1

Any of the various factors that causes a body to change its speed, direction or shape.

Answer 1

Force

Question 2

A region or space in which a given effect (such as magnetism) exists.

Answer 2

Force Fields

Question 3

A single force whose external effects on a rigid body are the same as the effect of several actual forces acting on the body.

Answer 3

Net force

Question 4

Forces that act between two objects that are not physically touching each other.

Answer 4

Non contact force

Question 5

A region composed of a group of atoms whose magnetic fields are aligned in the same direction.

Answer 5

Magnetic Domain

Question 6

A magnet that retains its magnetism after removal of the magnetizing force

Answer 6

Permanent Magnet

Question 7

Either of the two areas of the magnet where the magnetic field is the strongest. The North and South Poles are the strongest

Answer 7

pole

Question 8

A material of such low conductivity that the flow of current through it is negligible (usually rubber)

Answer 8

Insulator

Question 9

A substance, body, or device that readily conducts heat, electricity, sound, ect. (copper

Answer 9

Conductor

Question 10

The smallest unit of a chemical element. An atom consists of a dense central nucleus composed of protons and neutrons, surrounded by a cloud of rapidly orbiting electrons.

Answer 10

Atom

Question 11

A stable subatomic particle with a negative electric charge that is opposite to that of a proton but is equal in magnitude. (This is what gets transferred in electricity , and static electricity).

Answer 11

Electron

Question 12

An electrically neutral or no charge subatomic particle that has a mass slightly greater than that of a portion and is part of every atomic nucleus

Answer 12

Neutrons

Question 13

A stable subatomic particle that is part of the nucleus of an atom and has a positive electric charge. Its charge is opposite to that of an electron bit is equal in magnitude. The amount of protons depends on the individual element

Answer 13

protons

Question 14

Electric charge that accumulates on an object rather that flowing through it as a current.

Answer 14

Static Electricity

Question 15

`An electric motor is a device for converting electrical energy into mechanical energy in the form of rotation.

Answer 15

Electric Motor

Question 16

A device that consists of a coil of insulated wire wrapped around an iron core that becomes magnetized when and electric current flows through the wires.

Answer 16

Electromagnet

Question 17

A device that converts motion (kinetic energy) into electrical energy. A generator contains a coil wire that rotates within a magnetic field, producing an electric current in the wire.

Answer 17

Generator

Question 18

A coil of wire that acts as a magnet when and electric current passes through it.

Answer 18

Solenoid

Question 19

A device used to change the voltage of an alternating current in one circuit (the primary circuit) to a different voltage in a second circuit (the secondary circuit). A transformer consists of a frame of an easily magnetized material with two coils of wire wound around it. Each coil is connected to one of the two circuits.

Answer 19

Transformer
