Physics Motion

Question 1

Distance

Answer 1

To find distance, speed is beside time, so distance is speed multiplied by time.

Question 2

Speed

Answer 2

To find the speed, distance is over time in the triangle, so speed is distance divided by time.

Question 3

Meters

Answer 3

The Meter is the basic unit of length in the SI system of units

Question 4

Speed

Answer 4

Speed is the distance traveled per unit of time

Question 5

Magnets

Answer 5

Pieces of metal that attract other substances.

Question 6

Magnet Material

Answer 6

Materials magnets attract. For example, iron, steel, cobalt and nickel, as well as other magnets.

Question 7

Alloy

Answer 7

A mixture of two metals. Steel contains iron and cobalt

Question 8

Distance-time graph

Answer 8

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

Question 9

Current electricity

Answer 9

The steady flow of charge though wires and circuits.

Question 10

Static electricity

Answer 10

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

Question 11

Charged particles

Answer 11

Particles that have lost or gained electrons.

Question 12

Conductors

Answer 12

Particles that have lost or gained electrons.

Question 13

Insulator

Answer 13

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

Question 14

Negative

Answer 14

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

Question 15

Positive

Answer 15

An object that has lost electrons takes on a positive charge.

Question 16

Components

Answer 16

Objects in an electric circuit. The conversion of electrical energy into other forms takes place when that energy passes through these objects.

Question 17

Circuit diagram

Answer 17

An electronic circuit drawn using symbols

Question 18

Current

Answer 18

The steady flow of charge though wires and circuits.

Question 19

Potential difference

Answer 19

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 20

Voltage

Answer 20

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

Question 21

Resistance

Answer 21

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 22

Scalar

Answer 22

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

Question 23

Vector

Answer 23

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

Question 24

Displacement

Answer 24

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

Question 25

Velocity

Answer 25

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