Moton

Question 1

Distance

Answer 1

length between two points. Unit is metres (m).

Question 2

Speed

Answer 2

Distance travelled divided by time taken (m/s).

Question 3

Time

Answer 3

How long it takes to do something (s).

Question 4

Distance-time graph

Answer 4

Graph drawn using time on x axis and distance on y axis. The slope gives the speed.

Question 5

Current electricity

Answer 5

The steady flow of charge though wires and circuits.

Question 6

Static electricity

Answer 6

When two objects come into contact, electrons can transfer between them. When this happens, both objects become charged with static electricity.

Question 7

Charges particles

Answer 7

Particles that have lost or gained electrons

Question 8

Conductors

Answer 8

A substance that allows energy, such as heat or electricity, to pass through it easily.

Question 9

Insulators

Answer 9

A substance that does not allow energy, such as heat or electricity, to pass through it easily.

Question 10

Negative

Answer 10

Electrons have a negative charge. If an object gains electrons, it becomes negatively charged.

Question 11

Positive

Answer 11

An object that has lost electrons takes on a positive charge

Question 12

Components

Answer 12

the objects in an electrical circuit e.g. bulb, speaker.

Question 13

Circuit diagram

Answer 13

A drawing using symbols to represent how a circuit is set up.

Question 14

Current

Answer 14

the rate of flow of charge per second. Symbol is (I). Measured using an ammeter.

Question 15

Ammeter

Answer 15

Equipment used to measure current (I).

Question 16

Potential difference

Answer 16

When there is a point of high electrical energy and a point of low electrical energy in a circuit, there is a difference in electrical potential energy between these points. It is called potential difference.

Question 17

Voltage

Answer 17

Another word for potential difference. Measured in Volts (V) using a voltmeter.

Question 18

Resistance

Answer 18

a measure of how difficult it is for an electric current to pass through a substance.Unit is the Ohm. Measured using an ohmmeter.

Question 19

Scalar

Answer 19

A measurement that has size (magnitude) only. They do not have direction associated with them. E.g. distance, speed, time.

Question 20

Vector

Answer 20

A measurement that has size (magnitude) only. They do not have direction associated with them. E.g. distance, speed, time.

Question 21

Displacement

Answer 21

is the distance an object travels in a certain direction. E.g. 50 metres North.

Question 22

Velocity

Answer 22

is the speed of an object in a given direction. E.g. 10 m/s south.

Question 23

Distance-time graph

Answer 23

Graph drawn using time on x axis and distance on y axis. The slope gives the speed.

Question 24

Current electricity

Answer 24

The steady flow of charge though wires and circuits.

Question 25

Static electricity

Answer 25

When two objects come into contact, electrons can transfer between them. When this happens, both objects become charged with static electricity.

Question 26

Charges particles

Answer 26

Particles that have lost or gained electrons

Question 27

Conductors

Answer 37

a measure of how difficult it is for an electric current to pass through a substance.Unit is the Ohm. Measured using an ohmmeter.

Question 38

Example of nature selection

Answer 38

peppered moth. Lighter moths survive in less polluted areas, darker ones survive in the cities. The genes for light or dark wings are passed on more often depending, on where they live.
