Motion

Question 1

Distance

Answer 1

The length between two points. Unit is metres

Question 2

Speed

Answer 2

Distance travelled divided by time taken

Question 3

Time

Answer 3

How long it takes to do something

Question 4

Distance time graph

Answer 4

Graph diagram using time on x axis and distance on y axis this slope gives the slope

Question 5

Magnet

Answer 5

A piece of material that attracts other materials

Question 6

Magnetic material

Answer 6

Materials that are attracted to magnets e.g. iron

Question 7

Alloy

Answer 7

A mixture of two metals. Steel contains iron and cobalt

Question 8

Conductor

Answer 8

Particles flow through freely and conduct electricity

Question 9

Insulators

Answer 9

These do not let particles flow through them and don’t conduct electricity

Question 10

Negative

Answer 10

If an object loses neutrons it becomes negative

Question 11

Positive

Answer 11

If an object gains neutrons it becomes positive

Question 12

Changed particles

Answer 12

Under conditions static and current electricity involve the movement of changed particles

Question 13

Current electricity

Answer 13

The steady flow of change through wires and circuits

Question 14

Static electricity

Answer 14

Involves electric charge collecting in one place

Question 15

Component

Answer 15

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

Question 16

Circuit diagram

Answer 16

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

Question 17

Current:

Answer 17

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

Question 18

Current

Answer 18

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

Question 19

Antimeter

Answer 19

Ammeter: Equipment used to measure current (I).

Question 20

Potential difference

Answer 20

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 21

Voltage

Answer 21

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

Question 22

Resistance

Answer 22

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 23

Scalar

Answer 23

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

Question 24

Vector

Answer 24

A quantity that has magnitude and direction associated with them. e.g. displacement, velocity.

Question 25

Displacement

Answer 25

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

Question 26

Velocity

Answer 26

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