The 'highness' or 'lowness' of a sound is the pitch.

Physical Processes Vocabulary

Physical processes explain how forces, light, sound, and energy interact. In KS2 Science, pupils explore everyday effects like bending light, making sounds, and using electricity.

Fascinating Fact:

Refraction is when light bends as it passes through materials like glass or water.

In KS2 Science, pupils learn how physical processes shape the world around us. Concepts like reflection, refraction, forces, and sound waves help explain how energy moves and changes.

Key Terms

Refraction: The bending of light as it moves through different materials, such as air into water.
Force: A push or pull that changes how something moves, speeds up, or slows down.
Energy: The ability to make things happen, such as moving, heating, or producing sound.

Frequently Asked Questions (Click to see answers)

What are physical processes in KS2 Science?

Physical processes are natural effects like light, sound, forces, and electricity. They explain how energy moves and how objects interact in the real world.

What is the difference between reflection and refraction?

Reflection is when light bounces off a surface, like a mirror. Refraction is when light bends as it passes through materials such as glass or water.

Why are physical processes important to learn?

Learning about physical processes helps pupils understand everyday science, from how rainbows form to how electricity powers devices at home and school.

1 .

Which word means to bounce off a surface, without being absorbed?

Vibrate

Deflect

Traverse

Reflect

Mirrors reflect light

2 .

What do we call something which produces its own light?

A wave

A ray

A producer

A light source

Things like the Sun or a light bulb are light sources. The Moon and mirrors don't produce light - they merely reflect it

3 .

What do we call friction that is caused by air or water?

Newton

Temperature

Gravity

Resistance

If an object has a 'streamlined' shape it has less resistance with water or air

4 .

What do we call a push or a pull upon an object which is caused by another object?

A particle

A wave

A force

An energy

All forces are either pushes or pulls

5 .

Which force pulls everything towards the centre of the Earth?

Magnetism

Gravity

Air resistance

Friction

All large bodies, such as the Sun or the Moon, exert gravitational force

6 .

Which word describes the 'highness' or 'lowness' of a sound?

Vibration

Pitch

Transmission

Tune

Some sounds are high pitched, like a whistle. Others are low pitched, like thunder

7 .

What do we call a material which allows heat or electricity to pass through it?

An insulator

A circuit

A conductor

A thermometer

Insulators are the opposite of conductors - they stop or slow down heat and electricity

8 .

Which force is exerted by a surface when it rubs against another surface?

Friction

Gravity

Newtons

Forcemeter

Friction slows things down. It also generates heat

9 .

Which of these words means to spin on an axis?

Evolve

Rotate

Orbit

Attract

The Earth rotates on its own axis

10 .

Which force is caused by the pull of gravity on an object?

Weight

Mass

Air resistance

Volume

Weight changes if the force of gravity changes - objects do not weigh the same on the Moon as they do on Earth
